Fals - Kaykhusraw II Erzurum mint

Kaykhusraw II inherited the Rum Seljuk throne in 1237 under regency, his reign defined almost immediately by the Mongol invasion that culminated at the Battle of Köse Dağ in 1243 — a catastrophic defeat that reduced the sultanate to a Mongol tributary within a decade. The Erzurum mint was geographically among the first Anatolian production centers exposed to Mongol pressure from the east, making output from this facility during the 1240s increasingly erratic as administrative control fragmented.
