Founding of a Key Civil Rights Organization

The Civil Rights Movement was not just limited to the 1960s; it included earlier efforts and set the stage for future activism.

While various organizations emerged during this time, one pivotal development was the founding of a key civil rights group that would later play a major role in desegregation efforts and voter registration campaigns. This group's emphasis on nonviolent resistance and grassroots mobilization helped shape the movement's strategies well into the 1960s.
