There were constant conflicts between Vijayanagar and Bahmani over the control of the Raichur doab, which was the land between the rivers Krishna and Tungabhadra
The Vijayanagara Kingdom (1336–1565) and the Bahmani Kingdom (1347–1527) prospered for about two centuries.
For 200 years, they have been in war continuously and it seems that neither side won the battles, and the status quo was preserved.
Both kingdoms had strong, ambitious Kings who want to conquer and control the other's kingdom.
