C) Deva Raya I

Deva Raya I was one of the notable rulers of the Vijayanagara Empire. During his reign, he faced several military challenges, including conflicts with the Bahmani Sultanate.

One such significant event was the defeat of Deva Raya I by Firuz Shah, a Bahmani ruler. This defeat occurred during the Battle of Adoni in 1366 CE. Firuz Shah emerged victorious in this battle, which led to the Vijayanagara forces suffering a significant setback.

After his defeat, Deva Raya I had to pay a heavy indemnity to Firuz Shah. The indemnity consisted of ten lakhs huns and pearls, a considerable amount of wealth at that time. This payment was made as a tribute to the Bahmani ruler to secure peace and avoid further conflict.

Additionally, as part of the settlement, Deva Raya I also agreed to marry his daughter to Firuz Shah. This strategic alliance through marriage aimed to establish a more stable relationship between the two kingdoms and prevent future hostilities.

By agreeing to these terms, Deva Raya I sought to maintain peace and stability within his own kingdom and avoid further confrontations with the Bahmani Sultanate. This approach was crucial for the Vijayanagara Empire, as it allowed them to focus on internal development and consolidation of their power.

However, it is important to note that despite this defeat, Deva Raya I was a significant ruler who made significant contributions to the Vijayanagara Empire. He expanded the empire's territories, promoted cultural and architectural development, and implemented several administrative reforms. His reign marked a period of prosperity and growth for the Vijayanagara Empire.

In conclusion, Deva Raya I was defeated by the Bahmani ruler Firuz Shah in the Battle of Adoni. As part of the settlement, Deva Raya I had to pay ten lakhs huns and pearls as an indemnity and also married his daughter to the Bahmani Sultan.
