Abolition of slavery in the United States. The slave trade was abolished in the United States from 1 January 1808. However, some slaving continued on an illegal basis for the next fifty years. One popular subterfuge was to use whaling ships. The campaign to end slavery itself in the United States was long and bitter.
However in other areas it is still practiced to some degree. In the US, slavery supposedly ended in 1863 with the Emancipation Proclamation signed by Abraham Lincoln, and with the passage of the 13th Amendment in 1865. But slavery still exists in several forms throughout the country, like sex trading.
