The regatta festival started about 200 years ago as a display of naval strength of the Gungu people, where the Gungu warriors annually attacked dangerous hippopotamus that were destroying farmlands. Warriors would board various sizes of canoes with different types of weapons to attack the animal on the River Niger. This required expertise in canoe paddling and naval warfare. It also served as training exercise for upcoming Gungu warriors. (Photo by Toyin Adedokun/AFP Photo)
