Suldus
The Suldus were a Mongol tribe whose households assigned to Chagatai settled around Balkh and the upper Oxus. In 1337 these groups belonged to the Chagatai Khanate.
As the khanate disintegrated, the Suldus amir Buyan and Hajji Beg of the Barlas revolted against Qara’una rule in 1359, overthrowing Abdullah ibn Qazaghan. Buyan briefly influenced Transoxiana before Tughlugh Timur of Moghulistan executed him in 1362. Other Suldus groups moved west into Azerbaijan and Iran.
