When the Ilkhanate collapsed into rival Mongol tribes namely the Chopanids, Jalayirids, Muzaffarids and Injuids, their internal conflicts coupled with external invasions had rendered them weak and ideal targets for an invasion by Timur the Lame in 1393. He overran Iran, Iraq, Azerbaijan, Armenia, Georgia, and sacked portions of eastern Anatolia then returned to Samarkand by 1396. In this campaign he extinguished the Muzaffarids of Iran.
