What was the most important song of civil right movement?

The most important civil rights movement was "We Shall Overcome". It was written in 1945, and was sung by the labor union workers for the first time. It was only popularized by the civil right movement by the 1960s. The protest song has become a hallmark of the civil rights movement, and has been sung at rallies and protests around the world. It is a potent reminder of the movement's dedication to nonviolence and its determination to overcome segregation, racism, and other injustices.
