Oman–Zanzibar war
The Oman-Zanzibar war was a 1784 conflict between Oman and Zanzibar. It was the first time they had fought since 1779. Zanzibar, a colony of Oman, rebelled with the support of African forces from Mombasa and Pemba Island. Oman had to retake Zanzibar by force, capturing it in a short war. The Omani force was dispatched by Hilal bin Ahmad, eldest son of Ahmad bin Said al-Busaidi.
