In this tradition, the kingdom ruled vast territories from modern Wolaita up to the central and northern areas of the country.Its territories diminished to the present area because of different factors among which the Oromo expansion and challenges from rival people and states were the main ones.The new king Tona Gaga then set about raising an army personally loyal to him from "deposed castes and royal slaves."Menelik later marched south, calling on the king to pay tribute and spare his kingdom after reaching the border of Wolaita.Expertly dug defensive trenches and mounds crippled the initial assault, but encircling sweeps by Menelik's forces drove Tona Gaga onto the slopes of Mount Damota and he was soon caught between the Ethiopians and Oromo auxiliaries led by Ras Wolde Gyorgis, having been captured by a soldier of Negus Mikael.
