This former Swedish outpost on the Gold Coast was sold to the British in 1873 when, after decades of an uneasy relationship between the British and the Acing people of central Ghana, the British attacked and virtually destroyed the Asanti capital of Kumasi, and officially declared Ghana a crown colony on 24 July 1874. They then moved their administrative capital from Cape Coast Castle to Accra and their new acquisition, the Fort of Christianborg.
