What African leaders resisted the slave trade?

Several African leaders resisted the slave trade, notably King Affonso I of Kongo, who sought to limit the influence of Portuguese traders and protect his kingdom's interests in the 16th century. Another prominent figure was Queen Nzinga of Ndongo and Matamba, who fiercely opposed the Portuguese and their slave trade practices in the 17th century. Additionally, leaders like Yaa Asantewaa of the Ashanti Empire actively fought against both colonialism and the slave trade in the late 19th century. These leaders played significant roles in advocating for the rights and autonomy of their people against external exploitation.
