Answer:
The Civil War was an armed confrontation that took place between 1861 and 1865, between the states of the North, abolitionists and members of the Union; and the states of the South, slavers and grouped in the Confederation. During this conflict, more than 600,000 Americans died, which constituted the most lethal war that took place in the United States. Ultimately, the Union was victorious, and slavery was abolished throughout the country.
This war forever changed the concept of freedom in the country, as from this event began to be included within this concept to the entire population of the nation, and not just whites. In addition, it was a kind of continuity of the American Revolution, as it extended the natural rights of life, liberty and the pursuit of happiness to members of society who until then did not enjoy those rights.
