Zakho is known for its celebrations of Newroz.
The population of the town rose from about 30,000 in 1950 to 350,000 in 1992 due to Kurds fleeing from other areas of the country.<ref>{{Cite journal|last=Sabar|first=Y.|date=|title=Zāk̲h̲ū|url=|journal=Encyclopedia of Islam|volume=|pages=|doi=10.1163/1573-3912_islam_SIM_8099}}</ref>
The original settlement may have been on a small island in the Little Khabur river, which flows west through the modern city to form the border between Iraq and Turkey, continuing into the Tigris. Other important rivers in the area are the Zeriza and the Seerkotik.<ref>http://www.zaxo.at/index.php?page=32 {{Webarchive|url=https://web.archive.org/web/20110706095721/http://www.zaxo.at/index.php?page=32 |date=2011-07-06 }} retrieved 15 May 2011</ref>
==History== {{For timeline}} Gertrude Bell, the renowned British archaeologist and Arabist who advised British governors in the region in the closing years of the British Mandate, was convinced that Zakho was the same place as the ancient town of Hasaniyeh. She also reported that one of the first Christian missionaries to the region, the Dominican friar Poldo Soldini, was buried there in 1779. His grave was still a pilgrimage destination in the 1950s.<ref>{{cite book |title= Amurath to Amurath |publisher=Macmillan |last=Bell |first=Gertrude Lothian |year=1924 |url= https://archive.org/details/in.ernet.dli.2015.106098 |access-date=2009-09-06}}</ref><ref name="Campanile 1953">{{cite web |title= Histoire du Kurdistan |publisher=Le Kréyé|last=Campanile|first=Giuseppe|year=1953|url= https://www.institutkurde.org/publications/etude_kurdes/pdf/Campanile.pdf |access-date=2009-09-06}}</ref>
The town is also the site of Zakho castle, of which today only the tower remains, and of Qubad Pasha castle, a hexagonal structure in Zakho cemetery.
According to an oral tradition transmitted by a Jewish informant from Zakho, Me'allim Levi, Zakho was established in 1568 by Slivani tribesmen, whose territory was stretched south of the location of the town. The family of Shamdin Agha came originally from the Slivani tribe, settled in Zakho, and became the most prominent family in Zakho. From the late 19th century onwards, the family of Shamdin Agha ruled "all the Muslims, Jews and Christians of Zakho and its surroundings."<ref>Mordcechai Zaken, Jewish Subjects and their Tribal Vhieftains in Kurdistan, 2007: 33-35.</ref> Zakho was known to the ancient Greeks. In 1844, the traveller William Francis Ainsworth commented: "The appearance of Zakho in the present day coincides in a remarkable manner with what it was described to be in the time of Xenophon."
Zakho is a major marketplace with its goods and merchandise serving the Kurdish-controlled area and most of north and central Iraq. Writing in 1818, Campanile{{who|date=April 2020}} described the town as a great trading centre, famous for its gallnuts as well as rice, oil, sesame, wax, lentils and many fruits.<ref name="Campanile 1953" />
During the Crimean War, the strain on Ottoman military resources allowed Yezdanshir Beg, nephew of the Kurdish ruler Bedirkhan Beg, to launch a major rebellion in the region. In November 1854, he seized Jezira b. Omar, killed local Ottoman administrators, and extended his control toward Zakho. In early 1855, the Ottoman commander Helmy Pasha organized a relief force that included 2,000 Yazidi horsemen under the Mir Hussein Beg of the Sheikhan principality, who according to Hormuzd Rassam recognized Yezdanshir as a more dangerous enemy than the Ottoman governor who had recently deposed him. Yezdanshir was known for his openly hostile views toward Yazidis; the American missionary Henry Lobdell recorded hearing him declare that he wished to drink the blood of every Yazidi, Jew, and Christian he encountered. At Redwan, a British vice-consular source reported an eyewitness account of Yezdanshir personally killing between twenty-five and thirty Yazidis, having offered a bounty for live Yazidis to execute.<ref name=":0">{{Cite book |last=Guest |first=John S. |url=https://books.google.de/books/about/The_Yezidis.html?id=0gumEAAAQBAJ&source=kp_book_description&redir_esc=y |title=The Yezidis: A Study in Survival |date=2023-01-27 |publisher=Taylor & Francis |isbn=978-1-000-81750-8 |pages=112-114, 116 |language=en}}</ref>
Hussein Beg led his forces against the rebels outside Zakho, defeated them, and entered the town without resistance, formally capturing it "in the name of His Majesty the Sultan". For this service, Hussein Beg was received in audience by the sultan and awarded the title of ''kapi çuhadari'' (keeper of the official gate).<ref name=":0" />
=== Recent history === thumb|Joint forces headquarters in Zakho, 1993 Due to its strategic location and the abundance of job opportunities, Zakho has attracted many workers and job seekers from different parts of Iraq and even from Syria and Turkey. Trade with Turkey is now the major element of the economy.<ref>{{cite web|url=http://www.unhcr.org/refworld/topic,45a5199f2,45a519d32,4a697dee1e,0.html|title=KDP Flexes Muscles in Dohuk|date=2009-07-21|publisher=Institute for War and Peace Reporting|access-date=2009-09-06}}</ref> Oil drilling began in 2005.<ref>{{cite web|url=https://www.institutkurde.org/en/info/foreign-oil-deal-renews-debate-on-kurd-autonomy--1134220944.html|title=Foreign oil deal renews debate on Kurd autonomy|date=2005-12-09|publisher=USA Today|access-date=2009-09-06}}</ref>
====Islamic history==== In Islamic history it is perhaps best remembered as the location of the Battle of the Zab between the Umayyads and the Abbasids.
The river forms the approximate political boundary of Kurdistan Regional Government area of Iraq today. Its sister, the Little (or Lower) Zab rises in north-western part of Kurdistan province Iran, in the north of Piranshahr city and flows south-west through Iraq to join the Tigris north of the town of Baiji. The Dukan Dam straddles the Little Zab some 150 miles upstream from its confluence with the Tigris River. Constructed between 1954 and 1959, the dam has a total discharge capability of 4,300 cms. The power station, constructed in 1979, holds five water turbines and provides 400 MW of electrical energy.
In 1991, Zakho was occupied by the British and the Americans during the Gulf War in "Operation Provide Comfort", to provide support to the Kurdish rebellion against the Iraqi government. Most of the inhabitants of the city had fled to the mountains. In the following years, the city came under the control of the Kurdistan Autonomous Region and many of its Kurdish citizens began to return to the city.<ref>{{cite web|url=http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA254123&Location=U2&doc=GetTRDoc.pdf|archive-url=https://web.archive.org/web/20110604210725/http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA254123&Location=U2&doc=GetTRDoc.pdf|url-status=dead|archive-date=4 June 2011|title=Operation Provide Comfort: a model for future operations|last=Cavanaugh|first=John P.|year=1992|publisher=School of advanced military studies, Fort Leavenworth, Kansas|access-date=2009-09-06}}</ref>
The 27 February 1995 Zakho bombing killed over 50 people. When the U.S. Army closed its military base in Zakho in 1996, they evacuated several thousand Kurds who had connections to the base and who feared reprisals. Many of them were given asylum in the USA. According to David McDowall, this constituted a sudden brain drain, with Zakho losing many of its most educated citizens.<ref>{{cite book|url=https://books.google.com/books?id=dgDi9qFT41oC&q=a+modern+history+of+the+kurds|title=A modern history of the Kurds|last=McDowall|first=David|publisher=Tauris|year=2004|isbn=9781850434160|access-date=2009-09-06}}</ref>
In 2008 it was reported that the Turkish Armed Forces maintained four bases in Zakho District, under an agreement concluded with the Iraqi government in the 1990s.<ref>{{cite web|url=http://www.istockanalyst.com/article/viewiStockNews/articleid/2462785|title=Iraqi Kurdish Paper Says Turkish Military Bases Inside Kurdistan Region|date=2008-08-01|publisher=iStockAnalyst|archive-url=https://web.archive.org/web/20111004135848/http://www.istockanalyst.com/article/viewiStockNews/articleid/2462785|archive-date=2011-10-04|access-date=2009-09-06|url-status=dead}}</ref>
