How did freedom summer differ from earlier voter registration drives?

 One of the elements that helped to separate the Freedom Summer from other voter registration drive was the people who worked on this campaign. This campaign, aimed at increasing African-American voter registration in the state of Mississippi, resulted in thousands of volunteers helping. These volunteers included white citizens who were from out-of state. This ability to bring individuals from around the country to help with this voter registration project is a unique feature that few other registration drives had in this point in history.
