Somesvara IV (r. 1183–1200) is the last king of the Western Chalukya empire.

He makes a brief attempt to revive the Chalukya kingdom by defeating the waning Kalachuri kingdom.

He manages to capture Basavakalyana but fails to prevent the other feudatories, the Seuna, Hoysala and the Kakatiya dynasty from completely overwhelming the Chalukya empire.

In the end, the three feudatories divide the vast area between the Kaveri River and Narmada River among themselves.
