The American experiment was never a question of whether or not we would have slavery, it was always a discussion of how we would get rid of this deeply ingrained and sinful practice that had been around for thousands of years, and still exists in parts of the world today. But America managed to abolish the practice entirely within the 76 years between the First Constitutional Convention and the Civil War.
Slavery was a global institution. Thus, many states had laws designed to keep it intact — whether by mortgages, inheritance, or laws for buying, selling, and freeing slaves and severe penalties if you broke them. Vermont, for example, had no vested interest in slavery, and ended it in 1777, while states like South Carolina literally went down with the ship to keep it in 1865. The process was tedious and arduous, but America abolished slavery in the length of one lifetime — through Federalism, federal legislation, and Civil War.
So here is a timeline of slavery in America drawn primarily from the official website associated with 2005's four-part PBS documentary Slavery and the Making of America:
1776
The British colonies send the most epic break up letter in the history of the universe to Britain and we start the clock.
In Philadelphia, the Quakers forbid its members from holding slaves.
Delaware bans the importation of African slaves.
1777

1778
Virginia prohibits the importation of slaves.
1780

According to the Northwest Ordinance of 1787: "There shall be neither slavery nor involuntary servitude in the said territory," referring to all states northwest of the Ohio River.
See, while the North had already began abolishing slavery in several states, the South, which depended on slavery for their economy, argued that slaves were their property. However, they were also trying to count them as part of the population for census purposes.
Why was that important? If the south could successfully exploit the number of slaves for census purposes, that would mean they could acquire more representation and electoral votes to push forward their goals regarding keeping slavery legal and their own westward expansion. The northern delegates said absolutely not. After some debate, between 0/0 and 5/5 representation, they landed on 3/5s, which would ultimately leave the South short of the extra members of the House of Representatives and the electoral votes they needed.

“All Men Are Created Equal” has been an ever present purpose since the birth of America; a purpose fought and sacrificed for by imperfect men. No other country has tirelessly pursued a moral good like the United States of America and we should be proud of our integrity, our history, and the courage it took ordinary men to achieve extraordinary feats.
