1) Fort Sumter
The Battle of Fort Sumter was a bombing carried out between April 12 and 13, 1861, by the army of the Confederate States of America with the intention of expelling the federal troops that occupied the fortification of Fort Sumter, located at the entrance to the bay of Charleston in South Carolina. The importance of this battle, which did not cause casualties, is that it was the trigger that triggered the Civil War (1861-1865), the bloodiest conflict that occurred in the United States.
2) a larger population
the advantages in terms of population and resources of the North made it easier for him to win, but not inevitable. The Confederates did not need to invade and retain enemy territories to win, but simply to defend themselves to convince the North that the cost of victory would be too high. The North needed to conquer large enemy territories and defeat the Confederate armies to win.
3) a declaration to end slavery
In the presidential elections of 1860, the republicans, led by Abraham Lincoln, supported the prohibition of slavery in all the territories of EE. UU The southern states saw this as a violation of their constitutional rights and as the first step in a grand republican plan to finally abolish slavery.
