I've only ever heard of African American activists and their involvement in the Civil Rights Movement, such as Martin Luther King Jr., Malcom X, etc. Were there any other prominent figures representing other minorities in this time, or were they not as involved as the African American population?
Rabbi Abraham Joshua Heschel was a prominent figure in the civil rights movement and a close friend of MLK Jr., and read a psalm at MLK's funeral. Theres this famous picture of them both together at the Voting Rights March in Selma in 1965
Sixteen Jewish leaders were arrested in St. Augustine, FL in 1964, and that same summer two Jewish activists along with one Black activist were killed in Mississippi, during a time period known as the Freedom Summer. Although the relationship between Blacks and Jews has usually been rocky, it is undeniable that there are similarities between the struggles of the two peoples.
