There are people whose role in the history of the mankind cannot be underestimated. There are people to whom we are grateful for the way the world we live in looks like. One of those people is Rosa Parks. She is notable for an action which led to the racial equality nowadays. This action seems ordinary nowadays, but at that time, in 1955, it was an act of disobedience to the laws of that time, that were unfair from her point of view. It all happened on December 1, 1955 in Montgomery, Alabama. At that time, the first four seats were reserved for white people, and when they were all occupied, a black person from the seats behind the first four had to give up their seat to a white passenger. What Rosa Parks did was to refuse to give up her seat to a white man saying she thought she was not obliged to do that. As a result, she was arrested afterwards.
