How did the Civil Rights Activist work to chieve equality for african americans during the 1950's and 1960s?

Answer 1

boycotts, sit-ins, and other protests

Answer 2

I think you need to read one of the hundreds of books on this topic. The tactics ranged from sit ins to freedom riders and busses full of white northern college kids being bussed into the south..

It's a very extensive subject and, if you really want an answer other than a one sentance line you can use at school, then YOU need to do some research.
