Campaign to End Racial Segregation in Louisville. The full-scale assault on racial segregation in Louisville began in Feb. 1961, when local high school students staged non-violent demonstrations. Under leadership of the NAACP & CORE, they demanded passage of laws to end public racial discrimination. Fourth St. was hub of community activity where many protests and arrests occurred. (Reverse) Negotiations with city officials, demonstrations, an economic boycott, voter registration, and issue oriented voting led to the passage, on May 14, 1963, of a law making it unlawful for anyone to be refused service in a public place because of race, color, religion, or national origin.
