Shaykh Uways Jalayir, who at first had recognized the sovereignty of the Blue Horde, decided to take the former Chobanid lands for himself, even as a former amir of Malek Asraf’s named Akhichuq attempted to keep the region in Mongol hands. Despite a campaign that ended prematurely, as well as the brief conquest of Azerbaijan by the Muzaffarids, Uvais conquered the area in 1360. In addition to Baghdad, he could now boast Tabriz as a large city under his control.
