Question

Why did slavery continue after the revolution

Answer 1

You mean after the civil war?

Answer 2

The Founders were conflicted on what should be done. One the one hand there were people against the idea of slavery yet many of them, including Washington and Jefferson, had their fortunes built on slave labor. If slaves were recognized as full citizens then the southern states would have been in shambles economically speaking and, after 1787, would have given the south more representation in Congress. The solution was the 3/5ths Compromise, or having a slave be worth only 3/5ths of a free man.

Interesting note of fact: the word "slave" is nowhere to be found in the articles of the Constitution itself.
