The Hauka movement is a religious movement which arose in French colonial Africa. It consists of ceremonies, including mimicry and dancing, in which the participants perform the elaborate military ceremonies of their colonial occupiers. It was depicted in the 1955 short film Les maîtres fous directed by Jean Rouch, a well-known French film director and ethnologist. Hauka was popular in the late colonial and early post-colonial era, but the practice has since dwindled. However, as of the late 2010s, ceremonies continue to be practiced in certain circles in Niamey.
