Ap us history question:
although the 1960s are usually considered the decade of greatest achievement for black civil rights, the 1940s and 1950s were periods of equally important gains. assess the validity of this statement.

This statement is in general valid, since it points to the fact that although the 40s and 50s didn't produce as many tangible changes to Civil Rights as the 60s (with documents such as the Civil Rights Act), there were large-scale grassroots movements taking place during this time.
