Republican Philadelphia


Resolved: That the Constitution confers upon Congress sovereign powers over the Territories of the United States for their government; and that in the exercise of this power, it is both the right and the imperative duty of Congress to prohibit in the Territories those twin relics of barbarism - Polygamy, and Slavery.

The year is 1856. The issue of slavery divides the nation and threatens to tear it apart. As the country expands, tensions between slave-states and free states flare. Opponents of slavery are determined to halt the spread of the abominable practice into the new territories, eventually ending it altogether. A new political party, the Republican party, is formed to meet this ambitious goal

The Republicans called for the exercise of federal authority to halt the expansion of slavery, while the southern slave states defended their "peculiar institution" on the principle of state's rights.

The new party held its first convention in Philadelphia, the City of Brotherly Love. Philadelphia has gone on to host the convention a total of six times, most recently in 2000.
