Mandara

Mandara was a kingdom in the Mandara Mountains of present-day Cameroon. Its rulers conquered Dulo around 1580 and made it their capital.

In 1614 Bornu's ruler Idris Alaoma installed Aldawa Nanda on the throne, extending Bornu's influence. Around 1715 Mai Bukar Aji converted to Islam and made Mandara a sultanate. The Fulani leader Modibo Adama briefly captured Dulo in 1809, but a Mandara counterattack drove his forces out.
