mississippi was the first state to secede from the union
Mississippi in the American Civil War Mississippi was the second southern state to declare its secession from the United States of America, on January 9, 1861. It joined with six other southern slave-holding states to form the Confederacy on February 4, 1861. Mississippi's location along the lengthy Mississippi River made it strategically important to both the Union and the Confederacy; dozens of battles were fought in the state as armies repeatedly clashed near key towns and transportation nodes.
51st state Voters in Washington, D.C. and Puerto Rico have both voted for statehood in referendums.[2][3] As statehood candidates, their admission to the Union requires Congressional approval with the President's signature.[4]
Confederate States of America The Confederacy was established in the Montgomery Convention in February 1861 (before Lincoln's inauguration in March) and was disintegrated in April and May 1865. It was formed by delegations from seven Southern slave states that had proclaimed their secession from the Union. After the fighting began in April, four additional slave states seceded and were admitted. Later, two states (Missouri and Kentucky) and two territories were given seats in the Confederate Congress.
American Civil War The American Civil War (also known by other names) was fought in the United States from 1861 to 1865. As a result of the long-standing controversy over slavery, war broke out in April 1861, when Confederate forces attacked Fort Sumter in South Carolina, shortly after U.S. President Abraham Lincoln was inaugurated. The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States, who advocated for states' rights to expand slavery.
