Final answer:
Freedom Summer workers established freedom schools for voter education and formed the Mississippi Freedom Democratic Party to protest racial exclusion from politics. Despite facing violence and insufficient federal protection, these institutions were central to the Civil Rights Movement's efforts to combat disenfranchisement in the South.
Step-by-step explanation:
The Freedom Summer workers started several important institutions as part of their efforts in 1964. Most notably, they established freedom schools, which were informal schools aimed at educating African American citizens in various subjects, including reading skills necessary to pass literacy tests used to disenfranchise voters. The Freedom Summer workers were also instrumental in organizing the Mississippi Freedom Democratic Party (MFDP), which was formed to challenge the exclusion of African Americans from the state's all-white Democratic Party. Despite facing significant violence, harassment, and resistance, including the tragic murders of three civil rights workers, the Freedom Summer was a pivotal moment in the Civil Rights Movement. It highlighted the systemic racism and dangers faced by activists, although federal protection and intervention were woefully inadequate.
