Martin Luther King Jr was a man in action, wanting the caucasian and african american communities to come together, giving over 2500 speeches, his biggest speech I had a dream. He wanted peace between the two races because this was around the time where african americans could not go to white schools, eat in white resurants, go to white public bathrooms, or sit by white people on the buses. African Americans had seperate areas and Martin believed it wasn't fair or right.
I hope this helps you :)
