During the 13th century, when the gold mines in modern-day Mali started to dry up, Bonoman and later other Akan states began to rise to prominence as the major players in the gold trade.
I løbet af 1200-tallet, da guldminerne i nutidens Mali begyndte at svinde ind, begyndte Bonoman og senere andre Bonostater at vokse frem og blive betydelige aktører i guldhandelen.
