Garayusuf, the second ruler of the Garagoýunlys, was defeated and expelled by Timur (Tamerlane) a couple of times but he managed to return. After the death of Timur, Garayusuf recaptured in 1405 (807) all the lands he had formerly ruled. He took the Jelayirs under his rule in 1411. However, in 1469 (874) the Garagoýunly Turkmens accepted the rule and sovereignty of the Akgoýunly Turkmens, whose leader was then Uzun Hasan. 

(139.) 

Kara Yusuf’s era was the most marvelous period of the Garagoýunlys. By the death of Teymir, Garagoýunlys had became the most powerful state in the region. Kara Yusuf captured Mardin in 1409 and ended the Artykly dynasty. The Garagoýunly state became a great state after the conquests of Erzincan in 1410 and Soltaniye in Azerbaijan in 1415.
