adama ɓii ardo hassana (1786 – 1847), more commonly known as modibbo 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 fombina (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.
