When the framers designed the US Constitution they did not give the Federal government much power so power was balanced between States and Central Government. But the Federal government has gained more and more power over time. At the same time, the States were restricted over the years, when the Framers did not imagine doing so.

The American Civil War was an armed conflict that ran from 1861 to 1865 in the United States of America. In this conflict, American citizens were polarized on two fronts, that of the Union, which brought together the northern states of the country, and that of the Confederate States, which brought together southern states. This war, which resulted in more than 600,000 deaths, was the bloodiest in the history of the United States and the American continent.
