Simsir

Simsir was a medieval polity in the eastern North Caucasus, associated with the mountain and foothill country of Chechnya and its neighbors. Its rulers held lands at the meeting of the highlands and the plains, where local communities encountered the powers of the steppe. In 1395 Timur's campaign against the Golden Horde reached Simsir, whose ruler Gayur Khan resisted the invader. Timur defeated him and placed his son Makhama in a subordinate position, drawing the region into the turmoil of his war with Tokhtamysh.
