What are the "buses in Montgomery, the hoses in Birmingham, a bridge in Selma, and the song called 'We Shall Overcome'"?

 

She was there for the buses in Montgomery, the hoses in Birmingham, a bridge in Selma, and a preacher from Atlanta who told a people that "We Shall Overcome." Yes we can.

From wikipedia,
