The Republican Party was formed because of the desire of many to abolish slavery.

Explanation:

The Republican Party was founded on February 28, 1854 in Ripon, Wisconsin, by uniting the Free Soil Party and former members of the Whig Party. It was created as an association of opponents of slavery and supporters of the expansion of the authority of the central government, reflecting the interests of the industrialists of the North, opposed to the Democratic Party, which had a great support in the pro-slavery South.
