Gona Dynasty 
During the Kakatiya dynasty (995-1323), Gona Budda Reddy ruled a kingdom in Mahbubnagar district from Vardhamaanapuram (currently known as Nandi Vaddemaan) and Khilla Ghanpur (Fort Ghanpur) in modern-day Ghanpur, Mahbubnagar district. He and his family, the Gona dynasty, was mostly loyal to the Kakatiya dynasty. When he died, his brother Gona Lakuma Reddy took over the kingdom and rebelled against the Kakatiya, but his son Gona Ganna Reddy remained loyal to them in Vardamanapuram, (1262-1296 AD) indirectly supporting the rule of Kakatiya Queen Rudrama Devi against opposition to female rule.
