abstract:Leboku is the annual New Yam Festival celebrated in Ugep, Nigeria to honor of the earth goddess and the ancestral spirits of the land in Ugep, one of the five settlements of Yakurr. The three-week festival is the culmination of many events: the beginning of the yam harvest, a time to appease the gods and ancestors, a public parade of engaged maidens, a commemoration of events that led to the migration from the Yakurr ancestral home to the present site, and a period of holiday in the Yakurr traditional calendar (mid-August through mid-September).
