Phi Sigma Alpha traces its origins to several organizations including Phi Lambda Alpha. Phi Lambda Alpha fraternity was founded at the University of California, Berkeley, in 1919. The fraternity was the result of a merger of three societies: Pi Delta Phi Fraternity at Massachusetts Institute of Technology (MIT), founded in 1916; Phi Lambda Alpha Fraternity, founded in 1919 at the University of California, Berkeley;<ref>{{cite book | year=1922 | title=University of California Berkeley Blue & Gold Yearbook | publisher=University of California Berkeley | location=Berkeley, California | page= 600 }}</ref><ref>{{cite web| url=http://www.ic.sunysb.edu/clubs/phiota/fraternal_history.html| title=Beta Chapter Phi Iota Alpha Fraternity: Fraternal history| publisher=Stony Brook University| access-date=2008-01-03}}</ref> and the Unión Hispano Americana, founded in 1898, at Rensselaer Polytechnic Institute, Troy, New York. This last one was the first Latin-American student society formed in the USA;<ref name="Ricketts" /> A group of Latin American students organized the Unión Hispano Americana (UHA) as a cultural and intellectual secret society based on the ideology of Pan-Americanism.<ref>{{cite journal | title = Universities and world affairs | journal = Carnegie Endowment for International Peace | year = 1952 |issn = 0502-6393 }}</ref>
After '''{{lang|grc|ΦΛΑ}}''' was organized, other societies joined it: the Club Latino-Americano, founded in 1919 at Colorado School of Mines; the Federación Latino-Americana, founded in 1926 at Columbia University and which joined in 1928; the "Club Hispania" of Cornell University, founded in 1929, and which joined in 1931; the Club Hispano-Americano of Tri-State College in Angola, Indiana, founded in 1921, and which joined in 1929, and the Alfa Tenoxtitlan Militant chapter (founded in 1929) whose members had come from the former '''{{lang|grc|ΦΛΑ}}''' society in Mexico City, Mexico.<ref name="Sigma History">{{cite web|title=Sigma History |url=http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=23&Itemid=44 |access-date=2008-05-01 |language=es |url-status=dead |archive-url=https://web.archive.org/web/20110723022408/http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=23&Itemid=44 |archive-date=2011-07-23 }}</ref>
Sigma Iota fraternity was founded in Baton Rouge, Louisiana, on March 2, 1912, previously known as the Sociedad Hispano Americana, which was founded in the University of Louisiana in 1904. Between 1912 and 1925, Sigma Iota expanded rapidly in the United States, South America, and Europe. As a result of this, Sigma Iota became the first international Latin American-based fraternity.<ref name=Bairds91>{{Bairds20|page=VIII–22}}</ref>

Originally the name Kappa Delta Alpha was considered but it was quickly changed to Sigma Delta Alpha. By December 5, 1928, they established their chapter house where they began holding meetings.<ref name="Sigma History" />
For many years, Sigma Delta Alpha enjoyed a certain amount of notoriety not enjoyed by other student organizations at the university. Its membership included four of the most important student leadership positions at the university: the Yearbook editor, the senior class president, the Athletic Society president, and the ROTC Battalion Commander. Every activity sponsored by the school administration was consulted with the Sigma Delta Alpha chapter president at the university in Río Piedras.<ref name="Sigma History"/> In 1929, the ''Beta chapter'' at the Colegio de Mayagüez (University of Puerto Rico at Mayagüez) was established;<ref>{{Citation| last = | first = | language = Spanish| title = Se Constituye en El Colegio de Agricultura de Mayagüez el Consejo Beta de la sociedad universitaria Sigma Delta Alpha| newspaper = El Mundo (Puerto Rico)| pages = 13| date = October 24, 1929| url = https://gpa.eastview.com/crl/elmundo/?a=d&d=mndo19291024-01.1.13&srpos=1&e=------192-en-25--1--img-txIN-%22Sigma+Delta+Alpha%22---------| access-date = June 13, 2023}}</ref> thus the original chapter came to be known as ''Alpha chapter''.<ref>{{cite web | title=Beta Activo History| url=https://betafsaactivo.tripod.com//id1.html | access-date=2009-07-21 |language=es }}</ref>
===The union 1934–1939=== {{Main|Union Latino Americana}}
Phi Sigma Alpha had its first reorganization with the merger between the Alpha Boriquen Militant chapter of Phi Iota Alpha and Sigma Delta Alpha of the University of Puerto Rico in 1934. The Puerto Rican zone formed when the Alpha Boriquen Militant Chapter was founded in San Juan, Puerto Rico, on March 4, 1934, by former members of Phi Iota Alpha.<ref>{{cite web| url=http://www2.uic.edu/stud_orgs/greek/pia/FIAx/History.htm| title=FIA History| publisher=Fi Iota Alfa: Fraternidad Latino Americana| language=es| access-date=2009-07-21| archive-url=https://web.archive.org/web/20100718102746/http://www2.uic.edu/stud_orgs/greek/pia/FIAx/History.htm| archive-date=2010-07-18| url-status=dead}}</ref>
Under the conditions stated above, a movement came about to unite Sigma Delta Alpha with the Alpha Boriquen Militant Chapter of Phi Iota Alpha. It was not an easy task since many of the Sigma Delta Alpha members did not want the change or to alter their history. But the decision was made and thus the Phi Sigma Alpha Zone of the Union Latino Americana came to be.<ref name=Bairds49/><ref>{{cite book | last= Johnson | first=Clyde Sanfred | year=1972 | title=Fraternities in our colleges. | publisher=National Interfraternity Foundation | location=New York, New York | pages=42–43 }}</ref> A Zone Directive was created and a constitution was drafted, since there was no central body to control the fraternity.
By 1937, the ULA had several well-established and functional zones including:<ref name=Bairds49>{{Bairds15|page=315 }}</ref>
* Phi Iota Alpha in the United States * Phi Kappa Alpha in Cuba<ref>{{Bairds14|page=260 }}</ref> * Phi Sigma Alpha in Puerto Rico * Phi Tau Alpha in Mexico
ULA held its last Convention from January 7 to 8, 1938.<ref name="Sigma History"/> Delegates from the United States, Cuba, and the Puerto Rico zones were present. At the convention, agreement could not be reached over the ideals of the fraternity. After the convention, each zone considered the matter independently. The USA zone decided that the ideals of the ULA ought to be Pan-Americanism (the unification of Latin America by a system of confederacy) and led its members towards a position of pro-independence as it related to Puerto Rico, while the Cuban zone did not reach a decision on their own and ultimately decide to go along with the ideals conceptualized by the USA zone.<ref name="Sigma History"/>
The Puerto Rico zone rejected this decision because it considered the introduction of political issues to be detrimental to the fraternity. Thus on September 25, 1938, the Phi Sigma Alpha Zone withdrew from the Union Latino Americana.<ref>{{cite web| url=http://www.phiota.org/fraternalhist_sp.php| title=Historia Fraternal| publisher=Fi Iota Alfa: Fraternidad Latino Americana| language=es| access-date=2008-01-04| archive-url=https://web.archive.org/web/20071214195039/http://www.phiota.org/fraternalhist_sp.php| archive-date=2007-12-14| url-status=dead}}</ref> The ULA dissolved shortly after.
===The era of growth 1939–1964===
Like the members of the Sigma, a majority of the members (including two undergraduates, Ramon Garcia and Antonio A. Verrissimo) of the chapter of Phi Iota Alpha of the University of Louisiana disillusioned with the character given to their brotherhood, withdrew from the fraternity and formed Sigma Iota Alpha in April 1939.<ref name="Sigma History"/><ref>[https://repository.lsu.edu/cgi/viewcontent.cgi?article=1038&context=gumbo ''Gumbo (yearbook)'']. Louisiana State University, 1939.</ref><ref>''[https://repository.lsu.edu/cgi/viewcontent.cgi?article=1039&context=gumbo Gumbo (yearbook)]''. Louisiana State University, 1940.</ref> Sigma Iota Alpha was a fraternity composed of Latin students of that university. This new fraternity was received with distrust by the other Latin fraternal organizations at the university. Since Phi Sigma Alpha was organized in Puerto Rico with ideals similar to those of the Sigma Iota Alpha in Louisiana, negotiations were started to merge the two fraternities. This was decided in a convention celebrated on September 10, 1939, at the University of Puerto Rico, organizing themselves as {{Lang|es|Fraternidad Sigma}} (Sigma Fraternity) with two ramifications: Phi Sigma Alpha Zone in Puerto Rico and Sigma Iota Alpha Zone in Louisiana. Later the USA Zone's name was changed to Phi Sigma Beta Zone and came to include other universities in north Louisiana.<ref name="Sigma History"/>
The Phi Sigma Alpha Zone was organized by a board of directors of the zone, the Militant chapter Alpha Boriquén of San Juan, and two university chapters, one at U.P.R.-Río Piedras and another one at the U.P.R.-Mayagüez (then known as the Colegio de Agricultura y Artes Mecanicas de Mayagüez (CAAM)). Years later, the militant chapters of Ponce and Mayagüez were also organized.<ref>{{cite web | title=Sigma History | url=http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=5&Itemid=6 | access-date=2009-06-27 | language=es | url-status=dead | archive-url=https://web.archive.org/web/20090506181354/http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=5&Itemid=6 | archive-date=2009-05-06 }}</ref>
The Sigma Iota Alpha Zone (Phi Sigma Beta) consisted of the ''Alpha chapter'' at the University of Louisiana. In 1941, the ''Beta chapter'' in Baltimore, Maryland, was organized. It was composed of students from various nearby universities, including Georgetown, University of Maryland, University of Baltimore, Johns Hopkins, and George Washington University.<ref name="Sigma History"/> In November 1957, together with Phi Eta Mu and Phi Eta Mu. they founded a Greek letter umbrella organization Concilio Interfraternitario de Puerto Rico.<ref>{{cite news |last= |first= |date=November 22, 1957 |title=Fundan Concilio 3 Fraternidades |url=https://gpa.eastview.com/crl/elmundo/?a=d&d=mndo19571122-01.1.11&srpos=1&e=------195-en-25--1--img-txIN---------- |access-date=December 11, 2024 |newspaper=El Mundo (Puerto Rico) |publisher= |location=San Juan, Puerto Rico |pages=11 |language=Spanish}}</ref>
With time it became increasingly more difficult to sustain a fully functional zone in the United States, while pretending it worked as well as zone one in Puerto Rico. A reformist movement arose abroad and culminated in 1964 with the establishment of the Phi Sigma Alpha Fraternity composed of active and militant chapters in Puerto Rico, the United States, and abroad. Therefore, the model based on zones was abolished and eliminated.<ref name="Sigma History" />
===The era of progress and adaptations (1964) === {{Phi Sigma Alpha articles|right}}
Puerto Rico felt the economic boom of the post-Second World War years, and this boom was also evident in its universities. Puerto Rican youth registered in Puerto Rican universities in record numbers, and the Fraternity, which acted as the supplier of the union between its young people and an escape from arduous studies, also offered student housing. During the next two decades, Sigma enjoyed extensive enrollment in the original chapters as well as the new ones that were beginning to develop. While the baby boom effect declined dramatically in the late 1970s /early 1980s, it resurged at the end of the 1980s and continued until the beginning of the 1990s.<ref name="Sigma History"/>
{{Quote_box|width=30%|align=left|quote= "Un Sigma es ante todo un caballero"|source= Phi Sigma Alpha Creed}}
The 1990s brought an era of mandated accountability of fraternities, partly resulting from the deaths of two young cadets of the quasi-fraternal group the "Panthers" of the ROTC in the CAAM,<ref>{{cite web| url=http://www.zonai.com/noticia_mainm.asp?ZONAI:71311&pos=m&title=NOTICIAS&catid=61| title=Una tradición bélica| publisher=ZONAi| author=Firuzeh Shokooh Valle| date=2005-03-07| access-date=2008-01-04| archive-url=https://web.archive.org/web/20080415043156/http://www.zonai.com/noticia_mainm.asp?ZONAI:71311&pos=m&title=NOTICIAS&catid=61| archive-date=2008-04-15| url-status=dead}}</ref> and also a damages lawsuit perpetrated against another island fraternity. This brought forth a law, which can be found in Article 125 of the New Puerto Rico Penal Code, to control the initiation processes or "hazing" and to protect candidates.<ref>{{cite web| url=http://www.tribunalpr.org/CodigoPenal/acrobat/57a-Anejo-1-Camara.pdf| title=ANEJO 1, Informe de la Cámara| author=House of Representatives of Puerto Rico| publisher= Rama Judicial del Estado Libre Asociado de Puerto Rico| date=2004-04-27| access-date=2008-01-03}}</ref> The Sigma Brotherhood, which since 1959 had prohibited in its processes the use of the "Pledge Paddle", achieved another "first" from its prohibition of acts against the physical and mental dignity of the neophyte even before Article 125 was enacted.
The Sigma has continued its emphasis throughout the years on the areas of community and social work by its active and militant chapters which regularly take part in blood drives and fund-raising activities for different organizations. The "Beca Sigma" (Sigma Scholarship) program has been re-established and promises to offer young Puerto Ricans of scarce resources the opportunity to receive a university education.<ref name= Valle />
==Symbols and traditions== The fraternity's colors are Azure, Gules, and Or. Its motto is {{Lang|es|Caballeros Ante Todo}}. Brothers in active chapters are called {{Lang|es|activos}} and alumni Brothers are called {{Lang|es|militantes}}. Brothers also call each other Sigmas.
==Governance== The fraternity's highest administrative body is the {{Lang|es|Junta de Directores}} or Board of Directors. This body is composed of two groups. The first is the {{Lang|es|Comité Ejecutivo Central}} (Central Executive Committee) which includes the fraternity president, vice president, and others. The second group is composed of the regional presidents, and the presidents and secretaries of all the fraternity chapters, alumni, and active members.<ref name=Junta>{{Cite web | title = Junta de Directores | publisher = Fraternidad Fi Sigma Alfa | date = 2 January 2009 | url = http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=16&Itemid=38 | language = es | access-date = January 4, 2011 | archive-url = https://web.archive.org/web/20110723022355/http://www.fisigmaalfa.org/joomla/index.php?option=com_content&task=view&id=16&Itemid=38 | archive-date = 23 July 2011 | url-status = dead }}</ref> All members have an equal vote. The board of directors meets several times a year, as convened by the fraternity president.

== Club houses == Through its history the fraternity did have multiple chapter houses for most of its chapters. Nevertheless the practice became less and less common by the late 1990s in the Puerto Rico fraternity movement. Since then Phi Sigma Alpha has focused on nonresidential club houses.
Phi Sigma Alpha's main headquarters are located at the corner of Calle Mejico and Calle Chile in Hato Rey, Puerto Rico.<ref name="Valle" /> The offices are located in the ''Alpha Boriquen chapter's'' clubhouse, known as Casa Club Sigma.
