Answer:
1. It was in December 1860, that South Carolina seceded from the Union. The reason for the secession was because the elected president, Abraham Lincoln called for the abolition of slavery, and promoted equality and civil rights for African Americans. South Carolina (and majority of the South) advocated for slavery, because their economy relied heavily on slavery.
2. The secession did not become effective due to it being actively resisted by pro-Union state governments, this resulted in the American civil war between the two states. The North claimed that the secession was unconstitutional, thus illegal. the secession was thus unsuccessful due to the civil war which ended in April 9 1865.
3. The seceding of South Carolina was not justified because it was based on racist reasons. They even used the bible to justify slavery and how the Whit man is superior.
