"Such a person may not have formal tribal or other authority (through for instance material possessions, or inheritance of rights), but can maintain recognition through skilled persuasion and wisdom. The big man has a large group of followers, both from his clan and from other clans. He provides his followers with protection and economic assistance, in return receiving support which he uses to increase his status."
