The Spaniards were the first Europeans to establish a permanent settlement in what is now United States territory. The first settlement in modern-day United States territory was San Juan, Puerto Rico, founded in 1521 by Spanish explorer Juan Ponce de León. 35 years later, Spanish admiral Pedro Menéndez de Avilés founded the city of St. Augustine, Spanish Florida (the earliest settlement in the continental United States), which became a small outpost that never grew very large. More permanent, much larger territories were established in New Mexico and California, with a few in Texas and Arizona, forming part of the colonial history of the United States. Although the Spanish elements in the history of the United States were mostly ignored by American historians in the decades after independence, the concept of the "Spanish borderlands" in the American Southwest was developed by American historians in the 20th century, which integrated Spain into U.S. history.<ref>{{Cite journal|last=Weber|first=David J.|date=2005|title=The Spanish Borderlands, Historiography Redux|journal=The History Teacher|volume=39|issue=1|pages=43–56|doi=10.2307/30036743|jstor=30036743|issn=0018-2745}}</ref>

Spain provided indirect support to the new United States by fighting against Great Britain during the American Revolutionary War. Madrid tacitly recognised the independence of the United States in 1783.<ref>{{cite web | title=U.S. Relations with Spain | date=September 2025 | url=https://es.usembassy.gov/u-s-relations-with-spain/ }}</ref> The purchase of the underdeveloped Spanish Florida by the US was made effective in 1821. The U.S. gave diplomatic support to the breakaway Spanish viceroyalties as they secured their independence around 1820. American diplomatic offers to buy Cuba in the 1850s failed. When Cuba revolted in the late 19th century American opinion became strongly hostile to Spanish rule over Cuba. The Spanish–American War erupted in 1898. The Spanish defeat in the conflict entailed the loss of the last Spanish overseas territories outside north Africa, notably Cuba, Puerto Rico, Guam and the Philippines.

When the Spanish Civil War erupted in 1936, Washington was neutral and banned arms sales to either side; oil sales were allowed. Congress endorsed the embargo by a near-unanimous vote. President Franklin Roosevelt quietly favored the left-wing Republican (or "Loyalist") government, but intense pressure by American Catholics forced him to maintain a policy of neutrality. Spain was carefully neutral in World War II, despite its ties with Nazi Germany.

As the Cold War deepened after 1950, Washington threw a lifeline to the Francoist dictatorship that included financial aid and military bases. Membership in NATO came in 1982, after Francisco Franco's death and the Spanish transition to democracy.<ref>{{Cite book|url=https://books.google.com/books?id=i6YuAgAAQBAJ&pg=PA481|title=The Age of the Dictators: A Study of the European Dictatorships, 1918–53|last=Williamson|first=D.

==18th century== ===Spain and the American Revolution=== {{main|Spain and the American Revolutionary War}} [[File:Cuadro por españa y por el rey, Galvez en America.jpg|thumb|right|Painting of Gálvez at the Siege of Pensacola by Augusto Ferrer-Dalmau]] Spain declared war on Great Britain as an ally of the Kingdom of France, and provided supplies and munitions to the Continental Army. However Spain was not an ally of the Patriots. It was reluctant to recognize the independence of the United States, because it distrusted revolutionaries. Historian Thomas A. Bailey says of Spain: :Although she was attracted by the prospect of a war [against Britain] for restitution and revenge, she was repelled by the specter of an independent and powerful American republic. Such a new state might reach over the Alleghenies into the Mississippi Valley and grasp territory that Spain wanted for herself.<ref>Even worse, i (10th ed. 1980) pp 32–33.</ref>

Among the most notable Spaniards warriors was Bernardo de Gálvez y Madrid, Count of Gálvez, who defeated the British at Manchac, Baton Rouge, and Natchez in 1779, clearing the lower Mississippi Valley of British forces and relieved the threat to the capital of Spanish Louisiana, New Orleans. In 1780, he recaptured Mobile and in 1781 took by land and by sea Pensacola, leaving the British with no bases in the Gulf of Mexico. In recognition for his actions to the American cause, George Washington took him to his right in the parade of July 4 and the American Confederation Congress cited Gálvez for his aid during the Revolution.<ref>Eliga Gould, "Bernardo de Gálvez: Spanish Hero of the American Revolution by Gonzalo M. Quintero Saravia." ''William and Mary Quarterly'' 76.3 (2019): 597–600 [https://muse.jhu.edu/article/730595 online].</ref>

Floridablanca instructed the Count of Aranda to sign a Treaty with the United States on March 17, 1783, thus making Spain tacitly recognise then the independence of the US.{{Sfn|Hernández Franco|1991|p=185}}

Another notable contributor was Diego de Gardoqui, who was appointed as Spain's first minister to the United States of America in 1784. Gardoqui became well acquainted with Washington, and also marched in President Washington's inaugural parade. King Charles III of Spain continued communications with Washington, sending him gifts such as blooded livestock from Spain that Washington had requested for his farm at Mount Vernon.<ref>{{cite book | title=Spain and the Independence of the United States: An Intrinsic Gift | publisher=University of New Mexico Press | author=Chávez, Thomas E | year=2002 | location=Albuquerque | pages=12 | isbn=082632794X}}</ref>

===Spain and the United States in the late 18th century=== {{Main|Confederation period}} The United States' first ambassador to Spain was John Jay (but was not formally received at court). Jay's successor, William Carmichael, married a Spanish woman and is buried in the Catholic cemetery in Madrid. Some friendly ties were established: George Washington had established the American mule-raising industry with high-quality large donkeys sent to him by the King of Spain (as well as Lafayette).<ref>Paul Johnson, ''A History of the American People'' (New York: HarperCollins, 1997), 362.</ref>

[[File:John Jay at National Portrait Gallery IMG 4446.JPG|thumb|right|John Jay served as minister to Spain, and was Secretary of Foreign Affairs from 1784 to 1789]]

Spain fought the British as an ally of France during the Revolutionary War, but it distrusted republicanism and was not officially an ally of the United States. After the war, the main relationships dealt with trade, with access to the Mississippi River, and with Spanish maneuvers with Native Americans to block American expansion.<ref>Samuel Flagg Bemis, ''The Diplomacy of the American Revolution'' (1935, 1957) pp 95–102. [https://archive.org/details/TheDiplomacyOfTheAmericanRevolution online]</ref> Spain controlled the territories of Florida and Louisiana, positioned to the south and west of the United States. Americans had long recognized the importance of navigation rights on the Mississippi River, as it was the only realistic outlet for many settlers in the trans-Appalachian lands to ship their products to other markets, including the Eastern Seaboard of the United States.<ref>John Ferling, ''A Leap in the Dark: The Struggle to Create the American Republic'' (2003), pp. 211–212</ref> Despite having fought a common enemy in the Revolutionary War, Spain saw U.S. expansionism as a threat to its empire. Seeking to stop the American settlement of the Old Southwest, Spain denied the U.S. navigation rights on the Mississippi River, provided arms to Native Americans, and recruited friendly American settlers to the sparsely populated territories of Florida and Louisiana.<ref>Alan Taylor. ''American Revolutions A Continental History, 1750–1804'' (2016), pp. 345–346</ref> Additionally, Spain disputed the Southern and Western borders of the United States. The most important border dispute centered on the border between Georgia and West Florida, as Spain and the United States both claimed parts of present-day Alabama and Mississippi. Spain paid cash to American General James Wilkinson for a plot to make much of the region secede, but nothing came of it.<ref>George Herring, ''From Colony to Superpower: U.S. Foreign Relations Since 1776'' (2008), pp. 46–47</ref> Meanwhile, Spain worked on the goal of stopping American expansion by setting up an Indian buffer state in the South. They worked with Alexander McGillivray (1750–1793), who was born to a Scottish trader and his French-Indian wife, and he had become a leader of the Creek tribe as well as an agent for British merchants. In 1784–1785, treaties were signed with Creeks, the Chickasaws, and the Choctaws to make peace among themselves, and ally with Spain. While the Indian leaders were receptive, Yankee merchants were much better suppliers of necessities than Spain, and the pan-Indian coalition proved unstable.<ref>Lawrence S. Kaplan, ''Colonies into Nation: American Diplomacy 1763–1801'' (1972) pp 168–71.</ref><ref>Jane M. Berry, "The Indian Policy of Spain in the Southwest 1783–1795."

Spanish merchants welcomed trade with the new nation, which had been impossible when it was a British colony. it therefore encourage the United States to set up consulates in Spain's New World colonies<ref>Roy F.

John Jay negotiated a treaty with Spain to resolve these disputes and expand commerce. Spain also tried direct diplomacy offering access to the Spanish market, but the cost of closing the Mississippi to Western farmers for 25 years and blocking southern expansionists. The resulting Jay–Gardoqui Treaty was rejected by a coalition of Southerners led by James Madison and James Monroe of Virginia, who complained that it would hurt their people and instead favored Northeastern commercial interests. The treaty was defeated.<ref>Kaplan, 166–174.</ref><ref>{{cite book|author=Stuart Leibiger|title=A Companion to James Madison and James Monroe|url=https://books.google.com/books?id=eSftIw3YSTQC&pg=PT569|year=2012|pages=569–570|publisher=John Wiley & Sons |isbn=978-1118281437}}</ref>

Pinckney's Treaty, also known as the ''Treaty of San Lorenzo'' or the ''Treaty of Madrid'', was signed in San Lorenzo de El Escorial on October 27, 1795, and established intentions of friendship between the United States and Spain. It also defined the boundaries of the United States with the Spanish colonies and guaranteed the United States navigation rights on the Mississippi River. Both sides remained distrustful. Secretary of State Timothy Pickering feared that Spain might turn over Louisiana to her much more powerful associate France. Spain, by early 1797, was stalling the fulfillment of the 1795 treaty. Finally in 1798 Madrid backed down and relations improved.<ref>Gerald H. Clarfield, "Victory in the West: A Study of the Role of Timothy Pickering in the Successful Consummation of Pinckney's Treaty" ''Essex Institute Historical Collections'' (1965) 101#4 pp 333–353.</ref>

==19th century== ===Early 19th century=== Spanish–American relations declined during the 19th century, as both countries competed for territory and concessions in the New World. "Culturally, they misunderstood and distrusted each other", James W. Cortada has written. "Political conflicts and cultural differences colored relations between the two nations throughout the nineteenth century, creating a tradition of conflict of a generally unfriendly nature. By 1855, a heritage of problems, hostile images, and suspicions existed which profoundly influenced their relations."<ref>James W. Cortada, "Spain and the American Civil War: Relations at Mid-century, 1855–1868" (American Philosophical Society, 1980), 3.</ref>

During the Peninsular War, when Spain had two rival Kings – the overthrown Bourbon Fernando VII and Napoleon's brother, Joseph Bonaparte, enthroned as José I of Spain – the United States officially maintained a neutral position between them. Ambassador Luis de Onís who arrived in New York in 1809, representing Fernando VII's government, was refused an audience to present his credentials to President James Madison. He was only recognized officially by the US government in 1815, following Napoleon's defeat – though in the meantime he had established himself in Philadelphia and unofficially conducted extensive diplomatic activity.

The two countries found themselves on opposite sides during the War of 1812. By 1812 the continued existence of Spanish colonies east of the Mississippi River caused resentment in the United States. Escaped slaves went there and armed themselves. Spain stopped returning escapees in 1794.<ref>Richard K. Murdoch, "The Return of Runaway Slaves, 1790–1794." ''Florida Historical Quarterly'' 38.2 (1959): 96–113 [https://www.jstor.org/stable/30139019 online].</ref> With clandestine support from Washington, American settlers in the Floridas revolted against Spanish rule and Spain lost West Florida. Between 1806 and 1821, the area known as the "Sabine Free State" was an area between Spanish Texas and the U.S. Louisiana Territory that both sides agreed to maintain as neutral due to disputes over the area.<ref>James G. Cusick, "Some Thoughts on Spanish East and West Florida as Borderlands." ''Florida Historical Quarterly'' 90.2 (2011): 133–156 [https://www.jstor.org/stable/23035927 online].</ref><ref>James G. Cusick, ''The Other War of 1812: The Patriot War and the American Invasion of Spanish East Florida'';; (U of Georgia Press, 2007).</ref>

The Adams–Onís Treaty between the two countries was signed in 1819. The treaty was the result of increasing tensions between the U.S. and Spain regarding territorial rights at a time of weakened Spanish power in the New World. In addition to granting Florida to the United States, the treaty settled a boundary dispute along the Sabine River in Texas and firmly established the boundary of U.S. territory and claims through the Rocky Mountains and west to the Pacific Ocean in exchange for the U.S. paying residents' claims against the Spanish government up to a total of $5,000,000 and relinquishing its own claims on parts of Texas west of the Sabine River and other Spanish areas.

By the mid-1820s, Spaniards believed that the United States wanted to control the entire New World at Spain's expense, considering the independence movements in Latin America as proof of this.<ref>James W. Cortada, "Spain and the American Civil War: Relations at Mid-century, 1855–1868" (American Philosophical Society, 1980), 6.</ref> In 1821, a Spaniard wrote that Americans "consider themselves superior to all the nations of Europe."<ref>Quoted in James W. Cortada, "Spain and the American Civil War: Relations at Mid-century, 1855–1868" (American Philosophical Society, 1980), 9.</ref> In the United States, Spain was viewed as permanently condemned by the Black Legend, and as a backward, crude, and despotic country that opposed the Monroe Doctrine and Manifest destiny.<ref name="Cortada_9">James W. Cortada, "Spain and the American Civil War: Relations at Mid-century, 1855–1868" (American Philosophical Society, 1980), 9.</ref> Nevertheless, travel literature on Spain sold well in the US, and the writings of Washington Irving, who had served as U.S. Minister to Spain, generated some friendly spirit in the United States towards Spain.<ref name="Cortada_9"/>

===Mid-19th century=== Tensions continued throughout the 19th century. Queen Isabella II, who reigned from 1833 to 1868, became a dominant figure in Spanish-American relations. In 1839 she became involved in the ''Amistad'' affair, over the fate of the schooner ''La Amistad'' and the 53 slaves she carried. Isabella was one of several claimants to their ownership, and even after its resolution in 1841, following a U.S. Supreme Court decision, the Spanish government continued to press for compensation. She involved her country in the Chincha Islands War (1864–1866), which pitted Spain against her former possessions of Peru and Chile. The American Minister to Chile, Hugh Judson Kilpatrick, was involved in an attempt to arbitrate between the combatants of the Chincha Islands War. The attempt failed, and Kilpatrick asked the American naval commander Commander Rodgers to defend the port and attack the Spanish fleet. Admiral Casto Méndez Núñez famously responded with, ''"I will be forced to sink [the US ships], because even if I have one ship left I will proceed with the bombardment. Spain, the Queen and I prefer honor without ships than ships without honor."'' ("''España prefiere honra sin barcos a barcos sin honra''".) During the Chincha Islands War, Spanish Admiral Pareja imposed a blockade of Chile's main ports. The blockade of the port of Valparaíso, however, caused such great economic damage to Chilean and foreign interests, that the British and American governments lodged a formal protest.

During the mid-nineteenth century, one American diplomat declared:

{{Blockquote|You must treat Spain as you would a pretty woman with a bad temper. Firm and constant and unyielding in your purpose, but flexible and always flattering in form – watching her moods – taking advantages of her prejudices and passions to modify her conduct towards you... logic and sound policy will not guide her unless you take good care of the region of her sentiments first.|Horatio J. Perry<ref>Quoted in James W. Cortada, "Spain and the American Civil War: Relations at Mid-century, 1855–1868," ''Transactions of the American Philosophical Society'' (1980) Volume 70, Part 4, p. 105.</ref>}}

The romantic historian Washington Irving (1783–1859) was appointed minister by President John Tyler in 1842–1846. The history, customs, and pageantry of Spain seduced Irving. He admired the de facto head of state, regent Baldomero Espartero, then locked in a power struggle with the Spanish Cortes. Irving's official reports on the ensuing civil war and revolution expressed his romantic fascination with the regent as young Queen Isabella's knight protector, He wrote with an anti-republican, undiplomatic bias. Though Espartero, ousted in July 1843, remained a fallen hero in his eyes, Irving began to view Spanish affairs more realistically.<ref>Mary Duarte, and Ronald E. Coons, "Washington Irving, American Ambassador to Spain, 1842–1846." ''Consortium on Revolutionary Europe 1750–1850: Proceedings'' (1992), Vol. 21, pp. 350–360.</ref>

==== Cuba ==== But it was the issue of Cuba that dominated relations between Spain and the United States during this period. At the same time that the United States wished to expand its trade and investments in Cuba during this period, Spanish officials enforced a series of commercial regulations designed to discourage trade relations between Cuba and the U.S. Spain believed that American economic encroachment would result in physical annexation of the island; the kingdom fashioned its colonial policies accordingly.<ref name="Cortada_7">Cortada, "Spain and the American Civil War'' p. 7.''</ref>

In a letter to Hugh Nelson, U.S. Minister to Spain, Secretary of State John Quincy Adams described the likelihood of U.S. "annexation of Cuba" within half a century despite obstacles: "But there are laws of political as well as of physical gravitation; and if an apple severed by the tempest from its native tree cannot choose but fall to the ground, Cuba, forcibly disjoined from its own unnatural connection with Spain, and incapable of self support, can gravitate only towards the North American Union, which by the same law of nature cannot cast her off from its bosom."<ref name="Franklin">[http://ourworld.compuserve.com/homepages/jbfranklins/Cuba.htm Cuba and the United States : A chronological History] {{webarchive|url=https://web.archive.org/web/20071229093211/http://ourworld.compuserve.com/homepages/JBFranklins/Cuba.htm|date=December 29, 2007}} Jane Franklin</ref>

In 1850, John A. Quitman, Governor of Mississippi, was approached by the filibuster Narciso López to lead his filibuster expedition of 1850 to Cuba. Quitman turned down the offer because of his desire to serve out his term as governor, but did offer assistance to López in obtaining men and material for the expedition.

In 1854 a secret proposal known as the Ostend Manifesto was devised by American diplomats to purchase Cuba from Spain for $130&nbsp;million, thereby opening new slave territory. The manifesto was rejected due to vehement objections from abolitionist activists when the plans became public.<ref>J. Preston Moore, "Pierre Soulé: Southern Expansionist and Promoter." ''Journal of Southern History'' 21.2 (1955): 203–223 [https://www.latinamericanstudies.org/filibusters/Pierre-Soule.pdf online].</ref> When President James Buchanan addressed Congress on December 6, 1858, he listed several complaints against Spain, which included the treatment of Americans in Cuba, lack of direct diplomatic communication with the captain general of Cuba, maritime incidents, and commercial barriers to the Cuban market. "The truth is that Cuba", Buchanan stated, "in its existing colonial condition, is a constant source of injury and annoyance to the American people." Buchanan went on to hint that the US may be forced to purchase Cuba and stated that Cuba's value to Spain "is comparatively unimportant." The speech shocked Spanish officials.<ref>Quotes from Cortada, "Spain and the American Civil War" pp 26, 28.</ref>

==== Santo Domingo ==== Another source of conflict and rivalry was the Captaincy General of Santo Domingo, recreated when Spain annexed the independent Dominican Republic at the request of President Pedro Santana in 1861.<ref>Millery Polyné, "Expansion now!: Haiti," Santo Domingo," and Frederick Douglass at the intersection of US and Caribbean Pan-Americanism." ''Caribbean Studies'' (2006): 3–45 [https://www.redalyc.org/pdf/392/39211853001.pdf online].</ref> The U.S. and Spain had competed with one another for influence in Hispaniola in the 1850s and 1860s; the U.S. was worried about a possible military expansion by Spain in the Caribbean and the Gulf of Mexico (which would make it harder to acquire Cuba).<ref>Cortada, "Spain and the American Civil War" p. 30.</ref>

===Spain and the American Civil War and after=== {{main|Spain and the American Civil War}} thumb|right|Carl Schurz, Minister to Spain during the U.S. Civil War At the outbreak of the American Civil War, the Union was concerned about possible European aid to the Confederacy as well as official diplomatic recognition of the breakaway republic. In response to possible intervention from Spain, President Abraham Lincoln sent Carl Schurz, who he felt was able and energetic, as minister to Spain. Schurz's chief duty was to block Spanish recognition of, and aid to, the Confederacy. Part of the Union strategy in Spain was to remind the Spanish court that it had been ''Southerners'', now Confederates, who had pressed for annexation of Cuba.<ref name="Cortada_53_54">James W.

Horatio Perry was Secretary of the U.S. Legation in Madrid. His Spanish wife, Carolina Coronado (1820–1911), one of the most well-known poets writing in mid-19th-century Spain, played a role. She both negotiated with the Spanish royal family in private and, through a series of widely published poems, promoted the aims of the Lincoln administration, especially abolition. At a time when women were not invited to public political conversations, Coronado succeeded in persuasively arguing against Spain's imperial legacy and urging support to rectify her nation's past colonial blunders, especially the introduction of slavery to the Americas.<ref>Lisa Surwillo, "Poetic Diplomacy: Carolina Coronado and the American Civil War."

Grant took a keen interest; he clearly favored independence from Spain. He proposed American meditation, but Spain refused and the revolt slowly petered out.

Hostilities halted in August of that year, and the Treaty of Paris was signed in December.

American diplomats were responsive to the business community's demands for overseas expansion. Minister Hannis Taylor (1893–97) tried to support American business regarding Cuba. He was largely ignored, and he blamed Madrid's ineptitude.<ref>Tennant S. McWilliams, [https://www.jstor.org/stable/24909944 "Procrastination Diplomacy: Hannis Taylor and the Cuban Business Disputes, 1893–97.”] ''Diplomatic History'' 2#1 (1978), pp. 63–80</ref> In June 1897, President William McKinley appointed Stewart L. Woodford to the post of Envoy Extraordinary and Minister Plenipotentiary to Spain, in a last attempt to convince the Spanish government to sell its colonies. Spain refused and severed diplomatic relations with the U.S. on April 21, 1898.

The War was the first conflict in which military action was precipitated by media involvement. The war grew out of U.S. interest in a fight for revolution between the Spanish military and citizens of their Cuban colony. American yellow press fanned the flames of interest in the war by fabricating atrocities during the Cuban War of Independence, to justify intervention in a number of Spanish colonies worldwide, like Puerto Rico, the Philippines, Guam and the Caroline Islands.<ref>{{cite web |url=http://americanhistory.si.edu/militaryhistory/printable/section.asp?id=7 |title=The Price of Freedom: Americans at War – Spanish–American War |publisher=National Museum of American History |year=2005}}</ref>

Many stories were either elaborated, misrepresented or completely fabricated by journalists to enhance their dramatic effect. Theodore Roosevelt, who was the Assistant Secretary of the Navy at this time, wanted to use the conflict both to help heal the wounds still fresh from the American Civil War, and to increase the strength of the US Navy, while simultaneously establishing America as a presence on the world stage. Roosevelt put pressure on the United States Congress to come to the aid of the Cuban people. He emphasized Cuban weakness and femininity to justify America's military intervention.

Riots in Havana by pro-Spanish "Voluntarios" gave the United States the perfect excuse to send in the warship {{USS|Maine|1889|6}}. After the unexplained explosion of the ''Maine'', tension among the American people was raised by the anti-Spanish campaign that accused Spain of extensive atrocities, agitating American public opinion.

The war ended after decisive naval victories for the United States in the Philippines and Cuba, only 109 days after the outbreak of war. The Treaty of Paris, which ended the conflict, gave the United States ownership of the former Spanish colonies of Puerto Rico, the Philippines and Guam.

Spain had appealed to the common heritage shared by her and the Cubans. On March 5, 1898, Ramón Blanco y Erenas, Spanish governor of Cuba, proposed to Máximo Gómez that the Cuban generalissimo and troops join him and the Spanish army in repelling the United States in the face of the Spanish–American War. Blanco appealed to the shared heritage of the Cubans and Spanish, and promised the island autonomy if the Cubans would help fight the Americans. Blanco had declared: "As Spaniards and Cubans we find ourselves opposed to foreigners of a different race, who are of a grasping nature. ... The supreme moment has come in which we should forget past differences and, with Spaniards and Cubans united for the sake of their own defense, repel the invader.

In spite of having been proven false, many of the lies and negative connotations against Spain and the Spanish people, product of the American propaganda of the Spanish–American War, lingered for a long time after the end of the war itself, and contributed largely to a new recreation of the myth of the Black Legend against Spain.<ref>{{Cite web|url=http://link.galegroup.com/apps/doc/A11075070/LitRC?sid=googlescholar|title=The Black Legend: Spaniards hope to put an end next year to a propaganda campaign against their country that began half a millenium ago|last1=Duncan|first1=David Ewing|date=1991-08-01|website=Atlantic|language=en|access-date=2019-12-11}}</ref>

The article in ''El Sol'' also expressed the opinion that "the United States is a nation of realities, declaring that Spain in its foreign policy does not possess that quality."

In 1921, Luis Araquistáin wrote a book called ''El Peligro Yanqui'' ("The Yankee Peril"), in which he condemned American nationalism, mechanization, anti-socialism ("socialism is a social heresy there") and architecture, finding particular fault with the country's skyscrapers, which he felt diminished individuality and increased anonymity.

While in the United States, Federico García Lorca had stayed, among other places, in New York City, where he studied briefly at Columbia University School of General Studies.

===Spanish Civil War 1936–1939=== President Franklin D. Roosevelt named his favorite historian Claude Bowers (1878–1958) as ambassador to Spain from 1933 to 1939. Bowers prophesied that Washington's unwillingness to take action during the Spanish Civil War would make wider war inevitable. His influence was minimal in Washington.<ref>Little, Douglas.

When the Spanish Civil War erupted in 1936, the United States remained neutral and banned arms sales to either side. This was in line with both American neutrality policies, and with a Europe-wide agreement to not sell arms for use in the Spanish war lest it escalate into a world war. Congress endorsed the embargo by a near-unanimous vote. Only armaments were embargoed; American companies could sell oil and supplies to both sides. Roosevelt quietly favored the left-wing Republican (or "Loyalist") government, but intense pressure by American Catholics forced him to maintain a policy of neutrality. The Catholics insisted that lifting the embargo in favor of the Republican government "could only be the act of a hypocrite or a sucker" because, according to them, priests and nuns weren't given proper burials and were immolated by the anarchist elements of the Loyalist coalition. This successful pressure on Roosevelt was one of the handful of foreign policy successes notched by Catholic pressures on the White House in the 20th century.<ref>J.

The Nationalists, led by Francisco Franco, received important support from some elements of American business. The American-owned Vacuum Oil Company in Tangier, for example, refused to sell to Republican ships and at the outbreak of the war, the Texas Oil Company rerouted oil tankers headed for the Republic to the Nationalist-controlled port of Tenerife,<ref name="autogenerated3">Beevor, p.138</ref> and supplied tons of gasoline on credit to Franco until the war's end. American automakers Ford, Studebaker, and General Motors provided a total of 12,000 trucks to the Nationalists.

===World War II=== {{See also|Spain during World War II|Military history of the United States during World War II|Wolfram Crisis}} Francoist Spain sympathized with the Axis powers during World War II. While officially neutral, General Franco's government sold considerable material, especially tungsten, to both sides, including Germany. Thousands volunteered in the Blue Division, which fought for the Axis. As Germany weakened, Spain cut back its sales. Ambassador Alexander W. Weddell (1939–1942) managed to resolve a dispute over the National Telephone Company, the American owned (ITT) company that ran Spain's telephone system. He and Foreign Minister Ramón Serrano Suñer deeply disliked each other. Much more successful was historian Carlton J. H. Hayes who served as ambassador from 1942 to 1945.<ref>Charles R.

Instead he was "a tough critic of the caudillo's 'fascism'". Hayes played a central role in rescuing 40,000 refugees – French, British, Jews and others from Hitler. He helped them cross the Pyrenees into Spain and onward to North Africa. He made Spain "a haven from Hitler." In retirement, Kennedy finds, Hayes advocated patient diplomacy, rather than ostracism or subversion of Franco's Spain; this was the policy adopted by President Dwight D. Eisenhower as Franco led Spain into an alliance with the United States in the 1950s.<ref>[http://web.b.ebscohost.com/ehost/pdfviewer/pdfviewer?sid=8b5d43f8-c3b0-4f35-b494-3c3e2fbf9ce9%40sessionmgr110&vid=1&hid=114 Emmet Kennedy, "Ambassador Carlton J.

===Franco and the Cold War=== [[File:Franco eisenhower 1959 madrid.jpg|thumb|Francisco Franco and United States President Dwight D. Eisenhower in Madrid in 1959]] With the end of World War II, Spain suffered from the economic consequences of its isolation from the international community. Spain was blocked from joining the United Nations, primarily by the large Communist element in France. By contrast the American officials in 1946 "praised the favorable 'transformation' that was occurring in US–Spanish relations."<ref>{{cite book|author1=Matthew Paul Berg|author2=Maria Mesner|title=After Fascism: European Case Studies in Politics, Society, and Identity Since 1945|url=https://books.google.com/books?id=TP4WV3WTotoC&pg=PA52|year=2009|page=52|publisher=LIT Verlag Münster |isbn=978-3643500182}}</ref> United States needed Spain as a strategically located ally in the Cold War against the Soviet Union after 1947. Unlike the case of other European countries (where the United States' image was identified with a "liberating" function in World War II and a role as "generous" investors in the Marshall Plan) and not unlike the case of some Latin American countries, the image of the United States in Spain was thus constructed by and large upon the American cooperation with the Francoist dictatorship.<ref>{{Cite journal|journal=Cuadernos de Historia Contemporánea|year=2003|volume=25|url=https://revistas.ucm.es/index.php/CHCO/article/view/7743|location=Madrid|publisher=Ediciones Complutense|title=50 años de relaciones entre España y Estados Unidos|first=Antonio|last=Niño|page=29|issn=0214-400X}}</ref>

President Harry S. Truman was a very strong opponent of Franco, calling him an evil anti-Protestant dictator comparable to Hitler, Mussolini, and Hirohito. Truman withdrew the American ambassador (but diplomatic relations were not formally broken), kept Spain out of the UN, and rejected any Marshall Aid to Spain. However, as the Cold War escalated, support for Spain sharply increased in the Pentagon, Congress, the business community and other influential elements especially Catholics and cotton growers. Liberal opposition to Spain faded after the left-wing Henry A. Wallace element broke with the Democratic Party in the 1948 presidential election; the Congress of Industrial Organizations dropped its strong opposition and became passive on the issue. As Secretary of State Dean Acheson increased his pressure on Truman, the president, stood alone in his administration as his own top appointees wanted to normalize relations. When China entered the Korean War and pushed American forces back, the argument for allies became irresistible. Admitting that he was "overruled and worn down," Truman relented and sent an ambassador and made loans available in late 1950.<ref>Mark S. Byrnes,"'Overruled and Worn Down': Truman Sends an Ambassador to Spain." ''Presidential Studies Quarterly'' 29.2 (1999): 263–279.</ref>

In the context of the Arab–Israeli conflict, Spain played the role of mediator between the Arab countries (such as the Nasser's United Arab Republic) and the United States.

Torrejón passed under Spanish control in 1988; Rota has been in use since the 1950s. Crucial to Cold War strategy, the base did have nuclear weapons stationed on it for some time, and at its peak size in the early 1980s was home to 16,000 sailors and their families. The presence of these bases in Spain was very unpopular among the Spanish people (according to a 1976 poll by Louis Harris International, only 1 out of 10 Spaniards supported the American presence in the country);{{Sfn|Powell|2007|p=251}} there were occasional protests against them, including a demonstration during President Ronald Reagan's 1985 visit to Spain.<ref name=autogenerated2 />

During the Francoist dictatorship and later transition, Kissinger, related to the realist school, would support the notion of an orderly regime change for Spain, thus preserving access to the military bases as well as facilitating the full incorporation of Spain to the Western sphere, depending on Juan Carlos I.{{Sfn|Powell|2007|pp=227–229, 250}}

There was a brief strain in relations after the 1981 Spanish coup d'état attempt by neo-Francoist elements in the Civil Guard and Spanish Army, which Secretary of State Alexander Haig referred to as an "internal affair." A month after the coup was suppressed Haig visited Madrid to mend relations with the King, Prime Minister Leopoldo Calvo-Sotelo, and Leader of the Opposition Felipe González to prevent it from interfering with Spain's entry into NATO.

After the 2004 Spanish general election, in which the Spanish Socialist Workers' Party received more votes than expected as a result, besides other issues, of the government's handling of the 2004 Madrid train bombings, José Luis Rodríguez Zapatero succeeded Aznar as Prime Minister. Before being elected, Zapatero had opposed the American policy in regard to Iraq pursued by Aznar. During the electoral campaign Zapatero had promised to withdraw the troops if control in Iraq was not passed to the United Nations after June 30 (the ending date of the initial Spanish military agreement with the multinational coalition that had overthrown Saddam Hussein). On April 19, 2004, Zapatero announced the withdrawal of the 1300 Spanish troops in Iraq.<ref>{{Cite web|url=https://www.elmundo.es/elmundo/2004/04/18/espana/1082303152.html|title=Zapatero anuncia la retirada inmediata de las tropas de Irak|website=www.elmundo.es}}</ref>

The decision aroused international support worldwide, though the American Government claimed that the terrorists could perceive it as "a victory obtained due to 11 March 2004 Madrid train bombings". John Kerry, the Democratic candidate for the American Presidency, asked Zapatero not to withdraw the Spanish soldiers. Some months after withdrawing the troops, the Zapatero government agreed to increase the number of Spanish soldiers in the War in Afghanistan and to send troops to Haiti to show the Spanish Government's willingness to spend resources on international missions approved by the UN.

Spain under Zapatero turned its focus to Europe from the United States, pursuing a middle road in dealing with tensions between Western powers and Islamic populations.<ref name=autogenerated6 /> In a May 2007 interview with ''El País'', Daniel Fried, Assistant Secretary for European and Eurasian Affairs, commenting on the overall relationship between Spain and the United States, stated: "We work together very well on some issues.

==== Cuba ==== In 2007, Condoleezza Rice criticized Spain for not doing more to support dissidents in communist Cuba.<ref name=autogenerated5 /> American officials were irked by the fact that Miguel Ángel Moratinos, Minister of Foreign Affairs, chose not to meet with Cuban dissidents during a visit to the United States in April 2007.<ref name=autogenerated6 /> "There is no secret that we have had differences with Spain on a number of issues, but we have also had very good cooperation with Spain on a number of issues", Rice remarked.<ref name=autogenerated5 /> Moratinos defended his decision, believing it better to engage with the Cuban regime than by isolating it. "The U.S. established its embargo", he remarked. "We don't agree with it but we respect it. What we hope is that they respect our policy", Moratinos remarked. "What Spain is not prepared to do is be absent from Cuba. And what the U.S. has to understand is that, given they have no relations with Cuba, they should trust in a faithful, solid ally like Spain."<ref name=autogenerated6 />

==== Venezuela and Bolivia ==== thumb|right|Ibero-American Summit, 2007: Juan Carlos, Zapatero and Chávez are seated on the right. In addition to policy differences towards Cuba, the United States and Spain have been at variance in their dealings with Venezuela under Hugo Chávez and Bolivia under Evo Morales, both of them socialists.<ref name=autogenerated6 /> Spain under Zapatero was initially friendly to both regimes. However, Morales’ plan to nationalize the gas sector of Bolivia caused tension with Spain, as Repsol, a Spanish company, has major interests in that South American country.<ref name="autogenerated6" /> In regards to Venezuela, Zapatero also took issue with Chávez's elected socialist government. Spain's relations with Venezuela were further worsened by the November 10, 2007, incident at the Ibero-American Summit in Santiago, Chile, in which King Juan Carlos told Chávez to "shut up".

Despite its waning support for Chávez, Spain stated in May 2007 that it would pursue a €1.7&nbsp;billion, or $2.3&nbsp;billion, contract to sell unarmed aircraft and boats to Venezuela.<ref name=autogenerated6 /> In 2006, over 200,000 workers were employed by over 600 American firms operating in Spain. They were attracted by that country's low taxes, privatized state-owned companies, and liberalized economy. Furthermore, some 200 Spanish companies operated in the U.S., especially in construction and banking.<ref>Kurt Volker, "America and Spain: renewing a strategic partnership."

== Cultural relations == [[File:Spanish spoken at home in the United States 2019.svg|thumb|Spanish language in the US (2019)]] Spain-US relations have been seen as one of "love and hate".<ref name="autogenerated7" /> The groundwork was laid by the conquest of parts of the Americas by Spain before 1700. There are numerous influences from the Spanish colonial empire in the United States, parts of which were transferred to the US with the annexation of Florida and northwestern Mexico. Spanish influences have been preserved here in architecture, cuisine, and culture. In addition to the ethnically mixed group of Hispanics, there is also a group of Hispanos in the US who are direct descendants of Spanish settlers in New Mexico. Almost 60 million people in the US speak Spanish, just under a fifth of the population. In some regions of the country, Spanish has an informal status as a second official language. In the US territory of Puerto Rico, it is the official language alongside English. Spain is the third most popular country for foreign students from the US.<ref>{{Cite web |date=2025-01-30 |title=U.S. Relations with Spain |url=https://es.usembassy.gov/u-s-relations-with-spain/ |access-date=2025-09-09 |website=U.S. Embassy & Consulate in Spain and Andorra |language=en-US}}</ref> However, cultural relations have remained ambivalent. According to a study by the German Marshall Fund, feelings toward the United States in Spain are among the least positive in Europe. Reasons for this include memories of the Spanish-American War, support for Francisco Franco's dictatorship, and US interventions in Spanish-speaking Latin America. This sentiment is not limited to the left; anti-Americanism is also widespread among the right. During World War II, overt right-wing anti-Americanism, led by the Church, the armed forces, and the Falange, led Falange members to become advocates of a worldview shaped by Hispanidad, which was at odds with the Monroe Doctrine.<ref>William Chinslett: [https://core.ac.uk/download/pdf/42965626.pdf El antiamericanismo en España: el peso de la historia]</ref><ref>{{Cite journal |last=Fernández |first=Daniel |date=2006 |title=El antiamericanismo en la España del primer franquismo (1939-1953): el Ejército, la Iglesia y Falange frente a Estados Unidos |url=https://dialnet.unirioja.es/servlet/articulo?codigo=2010077 |journal=Ayer |issue=62 |pages=257–282 |issn=2255-5838}}</ref>
