Ambadeva

Amba-deva was a 13th-century chief who carved out an independent principality in present-day Andhra Pradesh in southern India. He was a member of the Kayastha family, whose members were vassals to the Kakatiya monarchs. Amba-deva succeeded his elder brother Tripurari as the Kayastha chief in 1272, and soon gave up allegiance to the Kakatiya queen Rudrama. He defeated several Kakatiya subordinates, and also fought against the neighbouring Pandyas and their vassals to carve out an independent principality with its capital at Valluru-pattana. A Kakatiya force sent by Rudrama's successor Prataparudra defeated him in mid-1291.
