American Civil War

The American Civil War was fought in the United States between states that supported the Union and southern states that seceded and formed the Confederate States of America. Slavery's status, particularly its extension into newly acquired area following the Mexican–American War, was the primary cause of the war. 

From April 12, 1861, until May 9, 1865, More lives were lost than any other American war. 

Slavery in the United States was a major political problem in the nineteenth century, with decades of political instability leading up to the conflict. After Abraham Lincoln won the 1860 presidential election on an anti-slavery platform, the country fell apart. The Confederacy was formed when seven Southern slave states declared their secession from the United States.

Slavery in the United States was a major political problem in the nineteenth century, with periods of continuous instability leading up to the conflict. After Abraham Lincoln won the 1860 presidential election on an anti-slavery agenda, the country fell apart. 

The Confederacy was formed when seven Southern slave states declared their independence from the United States. The proposed Crittenden Compromise crumbled after Confederate soldiers occupied multiple federal forts inside territory they disputed, and both sides prepared to fight.

In April 1861, just over a month after Abraham Lincoln's initial inauguration, the Confederate army launched the Battle of Fort Sumter in South Carolina. The Confederacy gained control of at least a majority of territory in eleven states, and claimed two more. 

The Union was made up of states that stayed faithful to the federal government. Large volunteer and conscription armies had been raised. Four years of intense combat, mainly concentrated in the South, began.

The Civil War is among the most researched and written-about periods in American history, and it continues to be a source of cultural and historical dispute. The concept of the Confederacy's "Lost Cause" is particularly fascinating. 

One of the first wars to use industrial combat was the American Civil War. Railroads, telegraphs, steamships, ironclad warships, and mass-produced armaments were all heavily deployed. The war claimed the lives of between 620,000 and 750,000 troops, as well as an unknown number of civilians. Only five days after Lee's surrendering, President Abraham Lincoln was assassinated.

Until the Vietnam War, the Civil War was the bloodiest military conflict in American history, with more American combat casualties than all other wars combined. I Civilian factories, mines, shipyards, banking, transportation, and food supplies were all mobilized ahead of the impact of modernization in World Wars I and II, as well as potential conflict.
