The Anaangs have a history and reputation for fearlessness and the ability of villages and clans to bind together to fight a common enemy. This is perhaps why they were able to thrive living so close to the Aro Confederacy's center, Arochukwu with its famed Ibini Ukpabi oracle. A particular interesting war group, or "Warrior cult", was the famous Oko warriors. This war group was highly functional in the 1950s. These warriors were considered invulnerable to penetration of knives, spears, and arrows. In various instances sharp machetes were tested on the body parts of members.
