The Sultanate of Bale was a Somali Muslim sultanate founded in the Bale Mountains of the southern Ethiopian Highlands and Horn of Africa. It corresponds roughly to the modern Bale Zone of the Oromia Region in Ethiopia.
History
Bale was the largest and most "wild" of the medieval sultanates of Ethiopia. Like most of the Islamic sultanates of Medieval Ethiopia, Bale was conquered by Amde Seyon in the 1320s, and would remain under Abyssinian occupation until Ahmeduddin Badlay's victory over Emperor Yeshaq I in 1429.
