Which of the following statements about the Civil War is FALSE?
a. Not all Southerners favored seceding from the Union.
b. The new Republican Party formed in the South to defeat abolitionists.
C. Southern states relied on slave labor to work large cotton plantations.
d. Protecting Galveston's port became a key task for Texans participating in the war.

b. The new Republican Party formed in the South to defeat abolitionists.

Explanation:

The American Civil War was fought between the North and the South from 1861- 1865. This civil war was fought mainly because of the abolition of the slavery system by President Abraham Lincoln. The Southern states who had seceded from the union were in support of the slavery system while the Northerners were in favor of abolishing the practice.

The one fact that is false from among the given statements is that the new Republican Party formed in the South was to defeat the abolitionists. In fact, this new party was formed by anti-slavery Whig parties on March 20, 1854, in Wisconsin which is now regarded as the founding meeting of the Republican party.
