The War of the Golden Stool, also known as the Yaa Asantewaa War, the Third Ashanti Expedition, the Ashanti Uprising, or variations thereof, was a violent battle in the series of conflicts between the United Kingdom and the Ashanti Empire, an autonomous state in West Africa that fractiously co-existed with the British and its vassal coastal tribes.
After several prior wars with British troops, Ashanti was once again occupied by British troops in January 1896. In 1900 the Ashanti staged an uprising. The British suppressed the violence and captured the city of Kumasi. Ashanti's traditional king, the Asantehene, and his counselors were deported. The final outcome was the annexation of Ashanti by the British so that it became part of His Majesty's dominions and a British Crown Colony with its administration undertaken by a Chief Commissioner under the authority of the Governor of the Gold Coast. Ashanti was classed as a colony by conquest. The Ashanti lost their sovereignty but not the essential integrity of their socio-political system. In 1935, limited self-determination for the Ashanti was officially regularized in the formal establishment of the Ashanti Confederacy.
