Explanation
* Krishnadeva Raya, the ruler of the Vijayanagara Empire (1509-1529), maintained friendly relations with the Portuguese. In 1510, with his permission, Alphonso de Albuquerque, the Portuguese governor, constructed a fort at Bhatkal, located in the Uttara Kannada district of Karnataka.
* Narasimha Saluva (**reigned 1491–1505) was a ruler of the Saluva dynasty, which briefly controlled the Vijayanagara Empire. The Portuguese presence in India was only beginning to take root during his reign, and their focus was primarily on establishing trade rather than fortifications.
* Muhammad Shah III (reigned 1463–1482) was a ruler of the Bahmani Sultanate, a medieval kingdom in the Deccan region. By the time of his reign, the Portuguese had not yet arrived in India (their arrival occurred in 1498).
* Yusuf Adil Shah: He was the founder of the Adil Shahi dynasty of Bijapur and ruled from 1489 to 1510. His engagements with the Portuguese were more conflictual, particularly over the control of Goa.
