1. Krishnadeva Raya as the most successful ruler of the Vijayanagara Empire
Krishnadeva Raya (1509 CE–1530 CE) was one of the ablest and most accomplished rulers of Vijayanagara. He won a series of outstanding victories and extended the boundaries of his empire, proving himself to be a brilliant general. He was also a wise and shrewd statesman who understood the importance of overseas trade and naval power, and he encouraged foreign trade with the Portuguese, who had set up trade centres on the Malabar Coast. He was a great patron of art and architecture — he donated large sums of money to temples, built many magnificent palaces, constructed dams for irrigation and took measures to improve agriculture. A great Telugu and Sanskrit scholar, he gave the Telugu language his patronage, under which it reached its peak. During his reign, the city of Vijayanagara was at the height of its prosperity.
2. Mahmud Gawan and his achievements
Mahmud Gawan was the Prime Minister of the Bahmani ruler Muhammad Shah III, and it was during his time that the kingdom reached its zenith. He was a gifted administrator as well as a skilled general, and the kingdom expanded under his leadership. He captured Goa and Dabhol, which were of strategic importance to the Vijayanagara kingdom, and also plundered Kanchipuram. He strengthened the power of the sultan and curbed the power of the nobles, and the land revenue system improved under his supervision. He encouraged education and spent almost his entire wealth in building a college (madrasa) at Bidar. As a newcomer (Afaqi), it was difficult for him to win the confidence of the Deccani nobles, who, jealous of him, got him executed by treachery in 1481 CE.
