Sadasiva Raya (r. 1542–1570 CE) was anEmperor of Vijayanagara who reigned from 1542 to 1570 CE.[1] When the Vijayanagara EmperorAchyuta Raya died in 1542 CE, his son,Venkata I (Venkata Raya orVenkatadri Raya), succeeded him. However, Venkata I was assassinated six months later. Sadasiva Raya, who was the nephew (sister-in-law's son) of Achyuta Raya, became the new Emperor in accordance with the Aliya succession laws prevalent among theTuluvas. Sadasiva Raya, along with his Prime MinisterRama Raya, restored the Vijayanagara empire's power, which had diminished after the reign ofKrishna Deva Raya. The strategy was to play theTurko-PersianSultanates in the Deccan against each other by first allying with one and then the other.[2]
