Explanation: The National Association for the Advancement of Colored People (NAACP) has been fighting for civil rights in America since 1909.
The organization's mission statement is "to ensure the political, educational, social and economic equality of minority group citizens of the United States." To this end, they have fought against lynching, segregation, and discrimination of various kinds.
In 1917, the NAACP led a legal challenge to segregated schools in Topeka, Kansas. The case was ultimately decided by the Supreme Court in 1954.
The NAACP also pushed for an anti-lynching bill in 1922; it passed but was blocked from being enforced by President Calvin Coolidge.
In 1940s, the NAACP worked against housing discrimination in Chicago and Detroit.
In 1954, Thurgood Marshall led an important case challenging segregation at public schools in South Carolina.
