Chalukya–Hoysala Wars

Timeline

1. 1121–1125Dangalur–Belur line · KarnatakaIn the final years of the long-lived Chalukya emperor Vikramaditya VI, Hoysala forces had broken past the traditional vassal relationship, repeatedly clashing with Chalukya border troops toward Dangalur and Belur, and cracks appeared in the Chalukya western vassal system.
2. 1126–1127Kalyani (Bagalkot) · KarnatakaAfter Vikramaditya VI's death, the Chalukya court fell into succession disputes and central military power was dispersed. The Hoysala seized the opportunity to advance, further weakening Chalukya practical control over Karnataka's core region.
3. 1128–1130Hoysala Kingdom (Halebidu–Belur) · KarnatakaBy around 1130 the Hoysala had established independent rule over large parts of Karnataka; though the Chalukya remained nominally a great Deccan power, their control over western and southern vassals was far weaker than before, laying the foundation for the later Hoysala zenith.
