Why is rosa parks considered a hero?

Rosa Parks is considered a hero because she encouraged people to end slavery. You might be thinking how she did that

On a day, Parks got on a bus. Of-coarse, later, a white man wanted her seat. They made they whites go at the front of the bus, and the others at the back. Parks did not like this rule. She wanted everyone to be free. She wanted freedom and rights. 

The man told her to get off the seat. She refused! Then, they all got mad. She would not give up her seat. It is said that they even physically tried to remove her from that seat!

Later, she was taken to Jail. She then encouraged African-Americans to boycott white buses, which made a HUGE difference in the white buses' pay. 

That made her a hero was that her story changed many things. She was a civil rights activist, which means she wanted rights for all. 

Here is one of her quotes that I thought was awesome:- "Have you ever been hurt and the place tries to heal a bit, and you just pull the scar off of it over and over again."
