Fals - Kaykhusraw II

Kaykhusraw II inherited the Seljuk throne of Rûm in 1237 under a regency, his reign defined almost immediately by the Mongol invasion that culminated in the catastrophic Seljuk defeat at Köse Dağ in 1243. After that battle, the sultanate became a Mongol vassal, paying tribute to the Ilkhanate and losing effective independence — a political collapse that makes any copper issue from this reign a relic of a state in the process of being absorbed. Copper fals of this period circulated in Anatolian markets still functioning under Seljuk administrative forms, even as the political reality above them had fundamentally changed.
