What Was the Cause of the Missouri Compromise?

The Missouri Compromise was made between Southern pro-slavery states and Northern anti-slavery states in order to keep the opposing states evenly numbered. The compromise helped keep balance between the two sides.

Passed in 1820, the Missouri Compromise was made between pro-slavery and anti-slavery states in the United States. It prohibited slavery in what was formerly the Louisiana Territory, minus the boundaries of the state of Missouri. Slaveholding states did not want to become outnumbered as they would lose the power to protect their interests. The Missouri Compromise would prove to be a temporary solution to the slavery crisis.

After passing the House on February 26, 1821, the conflict between the North and South intensified. It showed the Northern states that the Southern states had no intention for slavery to end. In 1853, the Kansas-Nebraska Act of 1854 repealed the dividing line in the Louisiana Purchase area for slavery.

In 1861, after a lot of tension between pro-slavery and anti-slavery states over the previous forty years, the American Civil War, also known as the War Between States, was waged. It was fought after seven Southern slave states formed the Confederate States of America, also referred to as the Confederacy. The war was the first true industrial wars and resulted in the deaths of an estimated 750,000 soldiers. Of these soldiers, 10 percent of Northern casualties were between 20-45 years old, and 30 percent of Southern casualties were between 18-40 years old.
