I also notice the repeated failure of folks that like to bring up Africans selling their own people to mention that not all African Countries were on board. In fact there were some that fought back
The Kingdom of Dahomey (present-day Benin): The Dahomey kingdom resisted the slave trade and even took part in capturing and enslaving other African groups to prevent them from being sold to Europeans.
The Ashanti Empire (present-day Ghana): The Ashanti Empire resisted the slave trade and even fought a series of wars against the British to prevent them from expanding their control over the region.
The Igbo people (present-day Nigeria): The Igbo people resisted slavery and often engaged in armed resistance against slave traders and European colonial powers.
The Somali people (present-day Somalia): The Somali people resisted the slave trade and often raided European ships to free enslaved Africans who were being transported across the Indian Ocean.
