 In the late 1800s, German explorers found them on the Serengeti plains of German East Africa now Tanzania.Archaeological evidence suggests that they were still in the Ngorongoro Highlands until around 150 years ago, before they were chased out by the Maasai, who live there to this day, still calling the area "Osupuko loo Ltatua" (Mountains of the Tatoga).The Tatoga then headed south along the eastern branch of East Africa's Great Rift Valley and eventually split into groups they call emojiga.
