They establish a market at Abonse, a few miles north-east of Akra. By doing so, the Ga succeed in confining the Akim and Akwamu traders at this market to trade only with them, and prevent them from coming into direct trading contact with the Europeans on the coast. The Akim Chiefdom essentially becomes a vassal of the Ga Chiefdom.
