The Vijayanagara Empire, also called the Karnata Kingdom, was based in the Deccan Plateau region of South India. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty, members of a pastoralist cowherd community that claimed Yadava lineage. The empire rose to prominence as a culmination of attempts by the southern powers to ward off Turkic Islamic invasions by the end of the 13th century. At its peak, it subjugated almost all of South India's ruling families and pushed the sultans of the Deccan beyond the Tungabhadra-Krishna river doab region, in addition to annexing modern day Odisha (ancient Kalinga) from the Gajapati Kingdom thus becoming a notable power. It lasted until 1646, although its power declined after a major military defeat in the Battle of Talikota in 1565 by the combined armies of the Deccan sultanates. The empire is named after its capital city of Vijayanagara, whose ruins surround present day Hampi, now a World Heritage Site in Karnataka, India. The wealth and fame of the empire inspired visits by and writings of medieval European travelers such as Domingo Paes, Fernão Nunes, and Niccolò de' Conti. These travelogues, contemporary literature and epigraphy in the local languages and modern archeological excavations at Vijayanagara has provided ample information about the history and power of the empire.
The empire's legacy includes monuments spread over South India, the best known of which is the group at Hampi. Different temple building traditions in South and Central India were merged into the Vijayanagara architecture style. This synthesis inspired architectural innovations in the construction of Hindu temples. Efficient administration and vigorous overseas trade brought new technologies to the region such as water management systems for irrigation. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit with topics such as astronomy, mathematics, medicine, fiction, musicology, historiography and theater gaining popularity. The classical music of Southern India, Carnatic music, evolved into its current form. The Vijayanagara Empire created an epoch in the history of Southern India that transcended regionalism by promoting Hinduism as a unifying factor.
