The late 1950s and 1960s marked a massive period of social upheaval, and no change was more prominent than those brought about by the US Civil Rights Movement. In 1964, thanks to activists like Rosa Parks and Dr Martin Luther King, African-American citizens were given similar rights to those of their white counterparts, and racial segregation and major institutional discrimination were outlawed.
