$MASKS

Traditional African Masks
Part 1
Traditional African masks are worn in ceremonies and rituals across West, Central, and Southern Africa. They are used in events such as harvest celebrations, funerals, rites of passage, weddings, and coronations. Some societies also use masks to resolve disputes and conflicts.
For example, members of the masquerade cult and Uma-Ada fraternity facilitate social justice and reconciliation processes among Igbo communities in Eastern Nigeria through masquerade performances.
Mende and Vai women of the Sande society in Sierra Leone don the Sowei mask during rites of passage, specifically initiation ceremonies for young girls. 
The Plank Mask (Nwantantay) among the Bobo, Bwa, and Mossi people of Burkina Faso makes an appearance during public events such as funerals and agricultural festivals.
