Answer: The Salvation Army
Explanation: (It was part of The Social Gospel Movement.)
It increased the amount of war and infighting in west Africa and depleted African resources.
During the ensuing decades, the abolitionist movement grew in Northern states, and Congress regulated the expansion of slavery as new states were admitted to the Union. Britain banned the importation of African slaves in its colonies in 1807 and abolished slavery in the British Empire in 1833.
The Haitian people eventually gained independence from France and became the first nation established by former slaves as a result of their struggle. The excesses of that despicable treatment were the very reason for the success of the Haitian Revolution: the treatment of slaves and Mulattoes in Haiti was so terrible that it prompted the most violent and eventually victorious slave insurgency in history. The Haitian Revolution was the first and only slave rebellion that resulted in the creation of a free state governed by non-whites and former slaves, free of slavery. This achievement needs to be remembered as one of history's major transformations in today's culture.
