Adama ɓii Ardo Hassana (c. 1771 – c. 1848), more commonly known as Modibo Adama, was a Fulani scholar and holy warrior, who hailed from the Ba'en clan of Fulbe. He led a jihad into the region of Fumbina (in modern-day Cameroon and Nigeria), opening the region for Fulani colonisation. As a result of Adama's constant warring, the Fulani today make up the largest ethnic group in Northern Cameroon (at more than 60% of the region's entire population, which considering the fact that they weren't from the area, is a remarkable feat), and Islam is the dominant religion. The wars also forced many peoples south into the forest region.
