ウズン・ハサン
With the death of Ilkhan Abu Said Bahatur in 1335, Mongol rule faltered and Persia fell into political anarchy. In 1381, Timur invaded Iran and became the founder of the Timurid Empire. His successors, the Timurids, maintained a hold on most of Iran until they had to submit to the "White Sheep" Turkmen confederation under Uzun Hassan in 1468; Uzun Hasan and his successors were the masters of Iran until the rise of the Safavids.
