According to some historians, the Battle of Fort Sumter marks the beginning of the Civil War.

Explanation:

The Civil War was a war (although Congress never issued a declaration of war) waged in the United States from 1861 to 1865. As a result of a historical controversy over slavery, war broke out in April 1861, when the forces of the Confederate States of America attacked Fort Sumter in South Carolina, shortly after President Abraham Lincoln took office. In response to the election of Abraham Lincoln as President of the United States, 11 states in the South, in which slavery was still legal, broke out of the United States and formed the Confederate States of America ("Southern States"). The other 25 states ("the North") supported the United States federal government. After four years of war, mostly fought on the territory of the Confederate States, the Confederation surrendered and slavery was banned throughout the nation.
