Kubad
The Kubadids were a small Turkmen emirate of the Canik group on Anatolia's Black Sea coast, with their capital at Lâdik. Their founder Tâceddin Altunbaş was a son of the Seljuk sultan Mesud II of Rûm; from about 1318 he ruled independently from Lâdik.
His son Keykubad kept the seat as a vassal of the Kutluşah rulers of Amasya, and Keykubad's son Ali was the first to bear the name Kubadoğlu. The family fought the neighbouring Taceddinoğulları for Samsun, which Ali and his son Cüneyd held with Bafra.
Bayezid I annexed Samsun in 1398 but left the Kubadids as Ottoman vassals. Timur's victory at Ankara in 1402 allowed a brief restoration, but Ottoman reconquest followed; Cüneyd was killed and after Hüseyin Bey's final attempt in 1422 the emirate disappeared. Its surviving line was said to have migrated to the Caucasus.
