The Battle of Gur Amba was fought on 27 September 1852 between the forces of the Ethiopian regent, Ras Ali II, and the rebel forces of Kassa Hailu. Kassa was victorious, and Goshu Zewde of Gojjam, the commander of the regent's forces, was killed. This was the first of a series of four victories which led to Kassa becoming Emperor Tewodros II of Ethiopia.This battle followed three years of peace between Kassa and Ras Ali, which ended in 1852 when Kassa refused to respond to Ras summons.
