Answer:
In some places, the slave trade increased the power of the African monarchy and led to economic strength. However, in places where there was competition between slave traders, the slave trade undermined the African monarchy, led to constant chaos/war, destroyed political unity, and disrupted African society. The slave trade also impacted demographics of Africa. Millions of people were lost to the slave trade. Also, in certain parts of African, certain genders were taken as slaves more than others. This disrupted marriage and the sexual distribution of labor in Africa.
