The Montgomery Bus Boycott

I read about this when I was in high school and I remember that a black woman would not give up her bus seat for a white man which got her arrested, and that led to a move by black people to stop riding the bus for a while which led to a huge loss of money by the company. I think that Rosa Parks not giving up her seat took a lot of courage for that day and age when there was white dominance. 25,000 black people rode buses at that time, and like everyone they had to pay to ride, losing thousands of customers was a wake up call that was effective by eliminating the rule that blacks must give up their seats for whites.  I believe this was the first step of how the Civil Rights movement began.
