Dirham - Kayka'us II Konya mint

Kayka'us II ruled the Sultanate of Rûm under increasingly impossible conditions — the Mongol victory at Köse Dağ in 1243 had reduced the sultanate to a tributary vassal of the Ilkhanate before his reign even began. He spent much of his rule either in open defiance of Mongol authority or in flight from it, eventually seeking refuge at the Byzantine court of Michael VIII after being deposed by his brother. Coins struck at Konya under his name thus span a politically fractured decade in which the mint's nominal issuing authority changed hands more than once.
