Hungarian authority fell over Bosnia in 1102, though it was ruled through a Ban, who became more independent as the century progressed. In the 1150s, Ban Borić, the first Bosnian ban known in historiography by name, led the Bosnian troops to aid Hungary against the Byzantines in Belgrade, as an ally. By 1180, Bosnia was functionally fully independent, though Hungarians seldom missed to lay the claim on it.
