On 6 March 1957 at midnight, the Gold Coast, Ashanti, the Northern Territories and British Togoland were unified as one single independent dominion within the British Commonwealth under the name Ghana. This was done under the Ghana Independence Act 1957. The current flag of Ghana, consisting of the colours red, gold, green, and a black star, dates back to this unification. It was designed by Theodosia Salome Okoh; the red represents the blood that was shed towards independence, the gold represents the industrial minerals wealth of Ghana, the green symbolises the rich grasslands of Ghana, and the black star is the symbol of the Ghanaian people and African emancipation.
