While white American slavery of an African labor force was abolished in the mid-nineteenth century, the scars from this long period of enslavement and forced labor have not healed, and hinder the growth and development of modern democracy to this day.

It becomes the first republic in the New World to be governed by a majority Black population1803: Denmark-Norway’s abolition of the slave trade, passed in 1792, takes effect. The impact on the slave trade is minimal, though, as Danish traders account for just over 1.5 percent of the trade by that date.1808: U.S. and British abolition takes effect. Britain was a major participant in the slave trade, and an immediate impact is seen. The British and Americans also begin trying to police the trade, arresting ships of any nationality that they find transporting slaves, but it is difficult to stop. Portuguese, Spanish, and French ships continue to trade legally according to the laws of their countries.1811: Spain abolishes slavery in its colonies, but Cuba opposes the policy and it is not enforced for many years. Spanish ships can also still legally participate in the slave trade.1814: The Netherlands abolishes slave trading.1817: France abolishes slave trading, but the law does not go into effect until 1826. 1819: Portugal agrees to abolish slave trading, but only north of the equator, which means that Brazil, the largest importer of slaves, could continue to participate in the slave trade.1820: Spain abolishes the slave trade.

It declines in 1830, but Brazil's enforcement of the law is weak and slave trade continues.1833: Britain passes a law banning slavery in its colonies. Slaves are to be released over a period of years, with the final release scheduled for 1840.1850: Brazil begins enforcing its anti-slave trade laws. The trans-Atlantic trade drops precipitously.1865: America passes the 13th Amendment abolishing slavery.1867: Last trans-Atlantic slave voyage.1888: Brazil abolishes slavery.
