Depends on how you look at it. Vermont was the first territory in 1777 to abolish slavery. In 1780 Pennsylvania was the first state to enact a law beginning abolition of slavery, freeing future children of slaves. Massachusetts was the first state to abolish slavery outright in 1783.
Massachusetts became the first colony to legalize slavery in the year 1641. Slavery is declared illegal in the Americas' Northwest Territory, or now known as the Midwest in 1787. And Abraham Lincoln issues the Emancipation Proclamation in 1863, or in other words, he stopped slavery trade among the Americans.
In the United States, slavery happened from the arrival of the first non-native Europeans until 1865. The Civil War turned into a war for the eradication of slavery. The end of slavery was made law via the 13th Amendment.
They did not like it because they, too, were sometimes forced into slavery.
There was multiple Presidents of American during slavery since slavery began around the start of the country as slaves were brought into American. In fact, the first President, George Washington, was in office with slavery occurring. Slavery then lasted up until Abraham Lincoln was the President who ended slavery as a result of the Civil War, but blacks, Native Americans, and immigrants would still be discriminated against until the later Civil Rights movement.
