To what purpose was the new republican party dedicated?

The Republicans rapidly gained supporters in the North, and in 1856 their first presidential candidate, John C. Fremont, won 11 of the 16 Northern states. By 1860, the majority of the Southern slave states were publicly threatening secession if the Republicans won the presidency. In November 1860, Republican Abraham Lincoln was elected president over a divided Democratic Party, and six weeks later South Carolina formally seceded from the Union. Within six more weeks, five other Southern states had followed South Carolina’s lead, and in April 1861 the Civil War began when Confederate shore batteries under General P.G.T. Beauregard opened fire on Fort Sumter in South Carolina’s Charleston Bay.
