Children want their freeom
Martin Luther king JR. and other people wanted the children to march so they can have their freedom. People will pay more attention to the kids in the march. The kids are doing the march together and not only 2 or 1 children. Kids had rights and couldn't be abused with either adults or other children in 1963.
Many black adults were to scared to march because they were scared that they might lose their jobs. So they might not take care of their money. Kids will go to jail and they will get hurt with water hoses and many more. Police officers let dogs go and attack the peaceful protesters and they also shoot high- pressure water hoses at them.
Children Crusade was a group of children(a lot) marching for their freedom to go to the same school and do what ever they want.
