Lincoln inspired by the principles of equality defended in the Declaration of Independence of the country, declared the end of the war based on the concept that the country was born to be a country of free people and owners of their own lives, the end of the war allowed freedom be offered to everyone, as the founding fathers wanted and fought for it.
