The American Civil War started in April 1861. The south claimed the right to leave the United States, also called the union, and form its own confederacy. President Lincoln led the northern states. He was determined to stop the rebellion and keep the country united. The north had more people, more raw materials for producing war supplies, and a better railway system. The south had more experienced military leaders and better knowledge of the battlefields because most of the war was fought in the south. The war lasted four years. Tens of thousands of soldiers fought on land and sea.
