Prior to the year 1856, the succession to the stool of Cape Coast (Oguaa) was patrilineal, that is, from father to son of a previous ruler. Egyir Ansah, Chief of Cape Coast, was succeeded from the male line by Burupu. Upon his death, he was also succeeded from the male line by Kofi Amissa.
He quickly developed a reputation as a cruel leader. As a result, a bloody riot or revolution took place on Wednesday, 23rd January 1856 involving two factions, Chief Kofi Amissa supported by No. 4 Asafo Company on one side and the other Asafo Companies on the other side. Chief Kofi Amissa and his allies were defeated and he was destooled on the 28th January, 1856. This event resulted the institution of the great Oath “Oguaa Wukudaa” since it occurred on a Wednesday.
In March 1856, the Oman and the Asafo Companies (the King Makers) as the victors of the upheaval, discontinued the patrilineal ascension to the stool. A change to matrilineal succession, in conformity with general Akan norms was instituted and the Birempong Kojo Ebiradzie Family (stool) was adopted the new Royal Stool of Cape Coast. Kweku Atta who was then, the Head of Birempong Kojo Ebiradze Family, Fikessim, Cape Coast, was the first Chief of Cape Coast from matrilineal line on the 12th March, 1856.
After the death of Omanhen Kweku Atta on the 20th February, 1856, he was succeeded by Kweku Enu, who enstooled on March 16, 1856 as the Second Omanhen from the matrilineal line. He died on 3rd February 1868. Upon his the death, he was succeeded by Omanhen Kwesi Atta, who also died in January, 1887. This is how matrilineal succession was restored to the Cape Coast Royal House.
