By the end of the Ilkhanid period in the mid-14th century, the Oghuz tribes that comprised the Aq Qoyunlu confederation roamed the summer pastures in Armenia, in particular, the upper reaches of the Tigris river and winter pastures between the towns of Diyarbakır and Sivas. Since the end of the 14th century, Aq Qoyunlu waged constant wars with another tribal confederation of the Oghuz tribes, the Qara Qoyunlu. The leading Aq Qoyunlu tribe was the Bayandur tribe.
