Battle of the Kondurcha River

Timur had previously assisted Tokhtamysh in taking the throne of the White Horde in 1378. In the following years both men grew in power, with Tokhtamysh taking full control of the Golden Horde while Timur expanded his power all over the Middle East. However Timur took Azerbaijan, which Tokhtamysh believed was rightfully Golden Horde territory. He invaded Timurid territory, briefly besieging Samarkand before being chased off by Timur. Timur pursued Tokhtamysh until the latter turned to fight him next to the Kondurcha River.
