What events took place that led to the civil rights movement?

the civil rights movement is the time when blacks and whits did not get along so they fought. like how martin Luther king jr. wrote i have a dream he was talking about the civil rights for black and white people. and how Rosa parks got arrested for not giving up he seat for a white man. that was worng and the whole contry knows it to but no white people stod up for this poor lady trying to live her life. everyone should know that this is not right. and if you see this happening that a white person is harasing a black or the other way around you should tell somebody and if it is really harsh call the police. that would be the right thing. we all know it is to so be nice to all colors no matter what.
