Oman–Zanzibar war

The Oman–Zanzibar war (حرب عمان - زنجبار; Vita vya Oman-Zanzibar) was a 1784 conflict between the Omani Empire 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 Sultan Ahmad bin Said al-Busaidi.
