<h2>Answer: The Reconstruction
</h2>
The Reconstruction was a period that came immediately after the end of the civil war in the United States, where the 11 southern confederate states tried to separate themselves from the rest of the country because of ideological differences, but mainly because of the slavery issue. Since the Southern states wanted to maintain the slavery system, while in the Northern states there were already free African-Americans.
This war broke out during the presidency of Abraham Lincoln and lasted four years (1861-1865), leaving thousands of dead on both sides and the southern territories (including crops and architecture) destroyed.
After the end of the war a period of tension was maintained, however Abraham Lincoln devised a plan to rebuild the southern states and reform the laws to give freedom to the slaves.
Lincoln was assassinated and the new president Andrew Johnson, continued with his position to unite the north and the south. It should be noted that during this period, which lasted twelve years, those who were slaves were given freedom and they were given <u>civil rights</u>, including the <u>right to vote</u>.
