The Vijayanagara Empire, founded in the 14th century by Harihara and Bukka, was a significant South Indian kingdom known for its cultural and architectural achievements. Key figures like Krishnadeva Raya expanded the empire and promoted arts and literature, while its military faced challenges from rival sultanates, culminating in its decline after the Battle of Talikota in 1565. The capital city, Hampi, featured advanced water management and fortifications that incorporated agricultural lands, reflecting its strategic importance.
