I would say that one of the most profound elements from the anti- slavery movement during the time period would be the groundswell that would lay the groundwork for the initial rejection of slavery. Abolition and anti- slavery movements fought for slavery to be banned in Pennsylvania, the first state to do so. This continued in the newly established Northwest Territory, which also extended the banning of slavery in territories north of the Ohio River and the Mason- Dixon Line. The anti- slavery movements during the late 18th and early 19th Centuries in America helped to establish the sentiment that one half of the nation would stand against slavery while others would not. The impact of anti- slavery movements and organizations sought to make their social issue a political one, and one that could be seen in legislative formats. This is another example of how the impact of anti- slavery movements can be seen in America of the time. In the end, the largest effect of the anti- slavery movements was to bring social awareness to the slavery condition in America, for the Constitution had not offered to speak to the issue. In this, the largest impact of the anti- slavery movements were felt.
