The Civil War of America started on April 12, 1861, and went on until April 9, 1865. It all started when the Confederate Army attacked Fort Sumter located in Charleston Bay in South Carolina.
Fort Sumter was then under the control of Union states who later managed to defeat the attackers. This war was brought about as a result of misunderstandings with regards to slavery, tariffs, state rights and trade.
However, it is widely believed that the war was triggered by the election of Abraham Lincoln as president, which compelled Southern states to secede. The war is estimated to have caused the deaths of 360,000 Union soldiers and 260,000 Confederate soldiers.
