An Abolitionist (practice called abolitionism) is a term given to people or a group of people who opposed the trading and possession of slaves and regarding the African and Native American slaves as less than a normal human being (such as being less than one of British ancestry or heritage).
In the new developing cluster of colonies, the Thirteen Colonies, a movement against slave labor and trade began in the later 18th century. One of the biggest groups of abolitionists, the Quakers, questioned the moral righteousness of slavery; from this point onward more movements began and ultimately marked the ending period of extensive slave labor and trading.
