With the end of the rainy season, Wodaabe nomads gather in the southern Sahel to celebrate one of their most anticipated traditions throughout the year, the gerewol festival. The men compete with each other by dancing, singing and performing for several days hoping that the young women will choose a husband for the marriage. Wodaabe men put on makeup and dress in their finest ornaments, reaching an almost trance-like state to impress women. South Sahel, Chad.
