In fact, the new American Government would maintain legalized chattel slavery (primarily of blacks) until the Emancipation Proclamation during the American Civil War. The movie however, implied at several points that the revolution also aimed to free blacks. And though some of the writers of the constitution favored abolition of slavery, most did not. The original compromise for determining population was the notorious policy of the three fifths clause which proclaimed that each slave counted as 3/5 of a person under the law, for the purposes of proportioning representation at the federal level.
