Yaa Asantewaa I was the Queen Mother of Ejisu in the Ashanti Empire, now part of modern-day Ghana. She was appointed by her brother Nana Akwasi Afrane Okese, the Edwesuhene, or ruler, of Edwesu. In 1900, she led the Ashanti war also known as the War of the Golden Stool, or the Yaa Asantewaa War of Independence, against the British Empire.

Queen mother is a term used to describe certain female traditional rulers in African cultures. Though there is no general description of a "queen mother", as their roles have varied by society, political context, and culture, they generally play an important role in local government and "wield social power and influence."
