Answer 2

The American Civil War (also known by other names) was a war fought in the United Statesfrom 1861 to 1865.[c] The Civil War is the most studied and written about episode in U.S. history.[16] Primarily as a result of the long-standing controversy over the enslavement of black people, war broke out in April 1861 when secessionist forces attacked Fort Sumter in South Carolina shortly after Abraham Lincoln had been inaugurated as the President of the United States. The loyalists of the Union in the North proclaimed support for the Constitution. They faced secessionists of the Confederate States in the South, who advocated for states' rights to uphold slavery.

Among the 34 U.S. states in February 1861, secessionist partisans in seven Southern slave states declared state secessions from the country and unveiled their defiant formation of a Confederate States of America in rebellion against the U.S. Constitutional government. The Confederacy grew to control over half the territory in eleven states, and it claimed the additional states of Kentucky and Missouri by assertions from exiled native secessionists without territory or population.
