Why do you think the Civil Rights Movement of the 60's and 70's referred to as the "Second Reconstruction?" (The first of course being Reconstruction following the Civil War.)

For abolishing Jim Crows segregation.

Explanation:

This movement abolished segregation in the south of the united states, which is why the change is called "Second Reconstruction." The first reconstruction involves the abolition of the slave system in the south of the country. The Second Reconstruction Movement provided civil rights to African Americans throughout the country.
