The Sultanate of Arababni (also known as Arbabni or Arabini) was a small Muslim sultanate located in what is now the Arsi Zone of Ethiopia.
[1] The Sultanate of Arababni was conquered by the Ethiopian Empire and made part of Fatagar.
Fatagar, and thus, Arbabni is the region southeast of the modern capital Addis Ababa, essentially corresponding to the modern West Shewa Zone and Arsi Zone.
The Fatagar region, being one of the former independent Muslim states in the region, was a primary target of the jihad of Ahmad ibn Ibrahim al-Ghazi, Imam of the Adal Sultanate.
During the reign of Emperor Amde Tsiyon I, Arbabni was conquered and annexed by Ethiopia and became part of the Fatagar province.
