Which explain why African slavery was introduced to the Americas early on?

African slavery was introduced to the Americans early on because of the needs of the country for laborers (for their farms). During these times, countries like France and Great Britain are in the country running different plantations. Americans are fighting them off, and some who they got caught in the warring times and some Africans whom they kidnapped from their homes were pushed to work for them in exchange for foods and accommodations. African slavery started in the 17th centuries and ended in 1863 when Abraham Lincoln made a proclamation of freeing all slaves in United States.
