History 

The West began ties with the Jaff tribe during World War I, when Ely Bannister Soane established contact. After the war, the tribe opposed Sheikh Mahmud Barzanji, as well as Great Britain's failure to grant Kurdish autonomy in Iraq. At the beginning of the 20th century, the tribe controlled one ninth of Iraq and controlled the communication system of the country. In 1933, about 100,000 rifles were in the hands of the tribe, contrary to the only 15,000 by the newly established Iraq. During this period, the tribe sedentarized.
