 The musical also deviates from history in its portrayal of attitudes about slavery.In "1776", after a dramatic debate over slavery, the southern delegates walk out in protest of the Declaration's denunciation of the slave trade, and only support independence when that language was removed from the Declaration.The walkout is fictional, as the debate over the wording of the declaration took place after the vote for independence on July 2, and apparently most delegates, northern and southern, supported the deletion of the clause.
