Osei Kofi Tutu I was one of the co-founders of the Empire of Ashanti, the other being Okomfo Anokye, his chief priest. The Ashanti were a powerful, warlike, and highly disciplined people of West Africa. Osei Tutu led an alliance of Ashanti states against the regional hegemon, the Denkyira, completely defeating them. Then, through force of arms and diplomacy, he induced the rulers of the other Ashanti city-states to declare allegiance to Kumasi, his capital. Throughout his career he was politically advised by Anokye, a cleric whose spiritual authority over the people aided in his founding of the empire.
The Empire of Ashanti was officially formed in 1701 and Osei Tutu was crowned Asantehene (King of all Ashanti). He would hold that position until his death in 1717 in a battle against the Akyem. Osei Tutu was the fourth ruler in Asante royal history, succeeding his uncle Obiri Yeboa. The Asante comprise the largest contingent of the Akan Twi-speaking peoples. Akan societies are matrilineal, with a person belonging to the abusua of his mother. Inheritance, succession and status are lineally determined. Osei Tutu belonged to the Oyoko Abusua.
Osei Kofi is a retired Ghanaian footballer. He played for Asante Kotoko F.C. and the Ghana national football team. He was a joint top scorer in the 1965 Africa Cup of Nations tournament held in Tunis, Tunisia leading to Ghana winning the tournament for a second time. He was the third highest scorer in the 1968 Africa Cup of Nations. Osei Kofi was called the 'wizard dribbler' because of his ball dribbling skills.
Osei Kofi apparently turned down a financial incentive to play in Europe at his prime in 1969. He later became a priest.
He has also worked as the National Coordinator for National Games.
