Answer:
Ā Ā Ā The end of the Civil War was won by the Union and, therefore, Lincoln decreed the abolition of slavery, a measure that came into force in 1865. In the same year, the president was assassinated by a southern fanatic. The southern states were devastated by the war and thus became economically and politically weakened.
Ā By abolishing slavery and serving the interests of the North, these states managed to bring great economic development to the country, turning the United States into a great capitalist power. On the other hand, freed blacks were not supported by any government program to integrate into society.
