Aliya Rama Raya's foreign policy during his time as the de facto ruler of the Vijayanagar Empire was marked by strategic alliances, diplomatic maneuvers, and military engagements with the neighboring Deccan Sultanates. His approach aimed to expand Vijayanagar's influence, manage regional conflicts, and safeguard the empire's interests. However, the consequences of his foreign policy choices, particularly his shifting alliances and conflicts with the Deccan Sultanates, ultimately led to the downfall of Vijayanagar.

1. Mediator and Diplomat: Aliya Rama Raya initially positioned himself as a mediator and diplomat between the various Deccan Sultanates. He leveraged his influence and diplomatic skills to resolve internal conflicts among the sultanates and maintain a balance of power in the region.
2. Territorial Expansion: Rama Raya sought to expand Vijayanagar's territorial control north of the Krishna River, taking advantage of the internal strife among the Deccan Sultanates. This expansionist policy aimed to strengthen Vijayanagar's strategic position and control key trade routes.
3. Alliances and Betrayals: One of the notable aspects of Aliya Rama Raya's foreign policy was his willingness to forge alliances with different sultanates based on short-term strategic gains. He supported various factions in their conflicts against rival sultanates, constantly shifting alliances to suit Vijayanagar's interests.
4. Effects and Consequences:
   • Strengths and Short-Term Gains: Initially, Aliya Rama Raya's foreign policy appeared to yield positive outcomes. He managed to extend Vijayanagar's influence, gain territorial control, and play a significant role in regional affairs.
   • Alliance Breakdown and Conflict: However, his constant switching of alliances and betrayal of former allies eroded trust and stability in the region. This led to the formation of a unified front by the Deccan Sultanates against Vijayanagar, culminating in the Battle of Talikota in 1565.
   • Battle of Talikota and Downfall: The Battle of Talikota proved to be disastrous for Vijayanagar. Aliya Rama Raya's foreign policy of constantly changing sides and manipulating conflicts backfired, as the united Deccan Sultanates decisively defeated Vijayanagar, leading to widespread destruction and the decline of the empire.

In summary, Aliya Rama Raya's foreign policy was characterized by opportunistic alliances, territorial ambitions, and diplomatic maneuvers. While initially successful in expanding Vijayanagar's influence, his policy of constantly shifting alliances and betraying former allies ultimately contributed to the empire's downfall and the end of its golden age.
