Unlike his brother, Mahadeva seems to have ruled the, chalukya kingdom from Nidadavole. Perhaps while Virabhadra was at Warangal, he succeeded Indusekhara on the throne. None of his records are available, though some important events of -the reign are known from the inscriptions of his children. The lower limit of his reign may have been A.D. 1306—the last date for Indusekhara, whereas the upper limit may have been either so long as he lived or so long the Kakatiyas kingdom lasted whichever happened sooner.
His Political Relations
Mahadeva II contracted alliances of marrige with the Kona Haihayas of Konamandala. For he married his daughter Oda-yamanadevi or Pina Gdayamabadevi to Kona Ganapatideva(A.D. 1254-1300) Prataparudradeva, son of Mahadeva II by Mummadamba succeeded Rudramadevi on the Kakatiya throne in A.D. 1296. Evidently on the death of Mahadeva II, Prataparudra inherited the chalukya kingdom of Vengi which got merged into the Kakatiya kingdom. So Mahadeva ohakravarti was the last of this line of the Chalukyas who ruled from Nidadavole.
Besides Annaya of the Induluri family, who was the co-brother-in-law of Mahadeva II. Ballepreggada and his son Nagamantri of the family of the guru Nukunaradhya were in the service of the Chalukyas of Nidadavole as ministers.
