Asafo are traditional warrior groups in Akan culture, based on lineal descent. The word derives from sa, meaning war, and fo, meaning people. The traditional role of the Asafo companies was defence of the state. As the result of contact with European colonial powers on the Gold Coast (present-day Ghana), the Fante, who inhabit the coastal region, developed an especially complex version of the concept in terms of its social and political organization based on martial principles, and with elaborate traditions of visual art, including flag banners with figurative scenes, and designs alluding to historical events or proverbs.
