The modern American civil rights movement, which began with the Montgomery bus boycott in 1955, was aimed at regaining the ground that had been achieved in the aftermath of the Civil War, such as through the enactment of the Fourteenth and Fifteenth amendments to the U.S. Constitution and of civil rights laws in 1866 and 1875, and moving toward the complete elimination of racial inequality in all its forms. Civil rights organizations pursued a variety of tactics, including lawsuits, boycotts, lobbying, sit-ins, freedom rides, street demonstrations, and marches, in attempts to demand freedom, equality, jobs, dignity, and an end to racial segregation, disfranchisement, and second-class citizenship.
