The Asante Kingdom developed in 1670s Ghana through the military conquests of Osei Tutu. He unified surrounding Akan chiefdoms and established Kumasi as the capital. Osei Tutu introduced the Golden Stool as a symbol of his divine authority over the Asante people. Under Osei Tutu and his successor Opoku Ware, the Asante Kingdom grew to control much of present-day Ghana through the gold trade and slave raiding of neighboring groups. The Asante remained a powerful kingdom into the 19th century before falling to European colonizers.
