American Civil War, also known as the
War Between the States or simply the
Civil War, was a civil war fought from 1861 to 1865, after seven Southern slave states declared their secession and formed the Confederate States of America. The states that remained in the Union were known as the "Union" or the "North". The war had its origin in the fractious issue of slavery, especially the extension of slavery into the western territories. Foreign powers did not intervene.
