King Tutu I decided to pursue the Akyems across River Pra against the advice of Okomfo Anokye. While crossing the river with his army, he was shot by the Akyems in an ambush. He was killed and fell into the river. The Ashantis say "Meka Yawada" which means "I swear by Thursday" because the day the king died was on Thursday and the Akyems were known as "Abuakwanfo" or "Abuakwafo" (guerrilla fighters). The Ashantis retreated and this defeat created a taboo preventing any Ashanti King up to the time of Nana Prempeh I (in 1900) to cross the Pra to the south.

After his death, his nephew King Opoku Ware I became the king of the Ashanti Empire and vowed to avenge his uncle's death. He restarted the war against the Akyems. The Akyems, knowing that the Ashantis would invade again, migrated southeastwards. Because of the travel, most of the Kotokus and some others settled in the present-day Ashanti Akyem region. The majority traveled until they met Akwamus, a powerful nation inhabiting and ruling the tribes from Asamankese to Nyanawase, which was then their capital and part of Akwapim. The Abuakwas fought the Akwamus and settled in the area of the Akwamus. The Abukawas made temporary capitals in several areas, including Praso, before settling at Pameng. In the reign of King Ofori Panin the capital was moved to Kyebirie. The Abuakwas fought few battles with their rival tribes and were an independent state until in 1852, the Abuakwas surrendered to the British Empire and they became a British administrative region.
