With the election of 1860, the republicans under Abraham Lincoln vowed to prevent the expansion of slavery, and they also demanded secession, that is the action to withdrawal formally from membership of a political state, among other federations or bodies.  South Carolina seceded from the union in December of the same year, and in February 1861 it joined the new Confederate States of America.

in february 1787, congress decided that a convention should be convened to revise the articles of confederation, the nation’s first constitution. in may, 55 delegates came to philadelphia, and the constitutional convention began. debates erupted over representation in congress, over slavery, and over the new executive branch. the debates continued through four hot and muggy months. but eventually the delegates reached compromises, and on september 17, they produced the u.s. constitution, replacing the articles with the governing document that has functioned effectively for more than 200 years.
