The Ashanti (or Asante) Empire (or Confederacy), also Asanteman (1701–1957), was a West Africa sovereign state of the ethnic Akan people of Ashanti, Brong-Ahafo, Central region, Eastern region, Greater Accra region and Western region, currently South Ghana. The Ashanti (or Asantefo) are of Akan origin. They are a martial and highly disciplined society of West Africa inhabiting an area known as "Akanland". They used their military power, which came from effective strategy and an early adoption of European firearms, to create an empire that stretched from central Ghana to present-day Benin and Ivory Coast, bordered by the Dagomba kingdom to the north and Dahomey to the east. Due to the empire's military prowess, wealth, architecture, sophisticated hierarchy and culture, the Ashanti empire was studied and had one of the largest historiographies by European, primarily British, sources of any indigenous Sub-Saharan African political entity.
