The Imo-Oka festival is a two weeks-long festival of masquerades and dances held in May at the beginning of the farming season in honour of a female deity who it is hoped would make the land fertile and yield bountiful crops.
There are four major events performed during the festival, the ede-mmuo, ogwu oghugha, egwu Opu-Eke and Egwu Imo-Oka.
