What did Martin Luther King Jr do that changed society?
Dr. Martin Luther King, Jr. stood up for what he believed was right. he stood up for african americans and other small minorties that were being discriminated against. he helped to change how we live by giving african americans the same opportunities that we(being caucasions) have. they no longer have to sit in the back of the bus, go to a different school, or even work a certain job. they have the freedom to do everything that we can do.
