Like Kulottunga I who united the chola and Chalukya kingdoms, Prataparudra united the Chalukya and Kakatiya kingdoms. But unlike Kulottunga, Prataparudra was the last ruler of the two dynasties, but not originator of a fresh invigorated line of rulers. For no sons and successors of Prataparudra are heard of. Throughout his reign the Muslim invasions proved a constant menaces to the security of the kingdom and evidence is clear that Induluri Rudra and Anna, the Gonas and the Sagis in the service of Prataparudra, and many great generals of his, protected the capital and kingdom and vanquished the enemy several times during the early years. But every defeat in the hands of the Hindus, increased the Zeal of the Muslims who came in larger numbers with great resources. Finally in A.D. 1323, the kingdom of Prataparudra fell before wrath of the Muslim Armies and thus ended the Chalukya—Kakatiya kingdom, like -the kingdoms of the Yadavas and the Hoysalas, about the same time.
