The Idoani Confederacy or Ido-ani confederation was a traditional state based in the town of Idoani in the Ose Local Government Area of Ondo State, Nigeria. The origins of the state date back to 1880 in the Kiriji/Ekiti Parapo war theatre at the height of the Yoruba Civil Wars when six separate villages/communities around the Ose river came together for the purpose of mutual protection from powerful warlords like Aduloju of Ado Ekiti and Ogedengbe of Ilesha encroaching and raiding the area while uprooting Ibadan hegemonic influences.
