Question

What was the basis for forming the Republican Party?

Answer 1

One of the major reasons for forming the Republican Party was "c. uniting several Northern antislavery coalitions," since the Republicans were highly anti-slavery. 

Answer 2

The correct answer is C.

In the year 1854, the Whig Party was disintegrated, for the founding of the Republican Party on March 20 of that same year.

The groups that joined to form the new party belonged to the powerful anti-slavery or abolitionist movement, which grouped all white-skinned people in the northern states of the United States.
