Candarids

The Candarid beylik was a Turkic principality centred on Kastamonu. In 1337 Süleyman I ruled Kastamonu and Sinop, having previously acknowledged Ilkhanid overlordship.

His sons fought over the succession, and the beylik was repeatedly divided between the two towns. In 1391 Süleyman II died defending Kastamonu against Bayezid I. İsfendiyar became an Ottoman vassal, but Timur confirmed his rule after defeating Bayezid in 1402. The dynasty retained Sinop until Mehmed II captured it and annexed the beylik in 1461.
