Oro Festival is an event celebrated by towns and settlements of Yoruba Origin. It is an annual traditional festival that is of patriarchal nature, as it is only celebrated by Male descendants who are paternal natives to the specific locations where the particular event is taking place. During the festival, females and non indigenes stay indoors as oral history has it that Oro must not be seen by women and non-participating people. The ceremonies surrounding the celebration of Oro differs from town to town, and one is often called after the death of a monarch.
