Answer:
The National Association for the Advancement of Colored People (aka the NAACP)
Step-by-step explanation:
The NAACP is a national organization that still exists today. This organization was founded by African American citizens with the goal of achieving social, legal, and economic equality. This organization was a fundamental part of the Civil Rights movement during the 1950's and 1960's.
For example, the NAACP was the organization that supplied the Brown family legal representation in the famous Brown vs. Board of Education case. The lawyers from the NAACP, like Thurgood Marshall, helped to end school segregation in the US by winning the case in Brown vs. Board of Education.
