Assertion (A): The Bahmani Sultanate, established in the Deccan by Ala-ud-din Bahman Shah, frequently engaged in prolonged military conflicts with the Vijayanagara Empire over the fertile Raichur Doab region. Reason (R): The Raichur Doab situated between the Krishna and Tungabhadra rivers possessed immense agricultural wealth, lucrative diamond mines, and control over crucial trade routes connecting the peninsula.

💡 Solution & Explanation

The strategic geopolitical struggle between the Bahmani Sultanate and the Vijayanagara Empire centered primarily on acquiring the fertile Raichur Doab because of its rich agricultural productivity and economic resources. The control of river basins guaranteed revenue collection and sustained military campaigns for both regional powers. This perpetual hostility defined medieval Deccan political history until the disintegration of the Bahmani kingdom.
