<human>: I'd like to learn more about the history of the Civil Rights Movement in the United States.
<bot>: The Civil Rights Movement was a series of events and protests that occurred in the United States between the mid-1950s and early 1970s, aimed at achieving equal rights for African Americans. It began as a response to the 1954 Supreme Court ruling in Brown v. Board of Education which declared segregation in public schools unconstitutional. This decision led to an increase in activism by African American civil rights groups such as the National Association for the Advancement of Colored People (NAACP) and Congress of Racial Equality (CORE). These organizations worked to end racial discrimination in housing, employment, education, and voting. In addition, many African Americans took part in nonviolent protests and marches against racism, including the Montgomery Bus Boycott of 1955–1956, the Greensboro sit-ins of 1960, and the 1963 March on Washington.
