prevent the disintegration of the empire and established the Tuluva dynasty of the Vijayanagara Empire. He was married to Srirangapatna's princess Tirumala Devi and a famous and his royal dancer from Kodagu, Chinna Devi. He was father to Tirumalamba (from Tirumala Devi), Vengalamba (from Chinna Devi) and Tirumala Raya (from Tirumala Devi). His daughters were married to Prince Aliya Rama Raya of Vijayanagara and his brother Prince Tirumala Deva Raya. Military career His main enemies were the Bahamani Sultans (who, though divided into five small kingdoms, remained a constant threat), the Gajapatis of Odisha, who had been involved in constant conflict since the rule of Saluva Narasimha Deva Raya, and Portugal, a rising maritime power which controlled much of the sea trade. Success in Deccan The raid and plunder of Vijayanagar towns and villages by the Deccan sultans came to an end during the Raya's rule. In 1509, Krishnadevaraya's armies clashed with them and Sultan Mahmud was severely injured and defeated. Yusuf Adil Shah was killed and the Raichur Doab was annexed. Taking advantage of the victory, the Raya reunited Bidar, Gulbarga, and Bijapur into Vijayanagar and earned the title "establisher of the Yavana kingdom" when he released Sultan Mahmud and made him de facto ruler. The Sultan of Golconda Sultan Quli Qutb Shah was defeated by Timmarusu, the prime minister of Sri Krishnadevaraya. War with Kalinga The Gajapatis of Odisha ruled a vast land comprising Bengal, Andhra region and Odisha. Krishna Deva Raya's success at Ummatur provided the necessary impetus to carry his campaign into Coastal Andhra region which was in control of the Gajapati Raja Prataparudra Deva. The Vijayanagar army laid siege to the Udayagiri fort in 1512. The campaign lasted for a year before the Gajapati army disintegrated due to starvation. Krishna Deva Raya offered prayers at Tirupati thereafter, along with his wives Tirumala Devi and Chinnama Devi. The Gajapati army was then met at Kondaveedu, where the armies of Vijayanagara, after establishing a siege for a few months, began to retreat due to heavy casualties. Then Timmarusu discovered a secret entrance to the unguarded eastern gate of the fort and launched a night attack that culminated with the capture of the fort and the imprisonment of Prince Virabhadra, the son of Prataparudra Deva. Vasireddy Mallikharjuna Nayak took over as governor of Kondaveedu thereafter. Krishnadevaraya planned an invasion of Kalinga, but Prataparudra, learned of this plan and
