Civil Rights Act of 1960
By the late 1950s, the Civil Rights Movement had been pressuring Congress to enact legislation to protect the constitutional civil rights of African Americans. The first major piece of civil rights legislation passed by Congress was the Civil Rights Act of 1957. While enforcing the voting rights of African Americans set out in the Fifteenth Amendment of the United States Constitution, the act had several loopholes. Southern states continued to discriminate against African Americans in application of voter registration and electoral laws, in segregation of school and public facilities, and in employment.
Presidency of Lyndon B. Johnson
Johnson signed the Civil Rights Act of 1964 into law on July 2. Legend has it that as he put down his pen Johnson told an aide, "We have lost the South for a generation", anticipating a coming backlash from Southern whites against Johnson's Democratic Party. The act banned racial segregation in public accommodations, banned employment discrimination on the basis of race or gender, and strengthened the federal government's power to investigate racial and gender employment discrimination. The law later upheld by the Supreme Court in cases such as "Heart of Atlanta Motel, Inc. v. United States".
