Final answer:
The tactics used by civil rights groups in promoting civil rights included legal action in the courts for desegregation, youth-led sit-ins at universities, and long occupations that attracted media attention.
Step-by-step explanation:
The tactic of legal action in the courts for desegregation was used by African American civil rights activists in the 1950s and 1960s. They filed lawsuits challenging racial segregation in schools, transportation, and other public facilities. This tactic was successful in several landmark cases, such as Brown v. Board of Education.
The tactic of youth-led sit-ins at universities was another strategy used by civil rights activists. African American students would peacefully occupy segregated spaces, such as lunch counters, in places like Greensboro, North Carolina, in order to protest and challenge racial segregation.
The tactic of long occupation that attracted media attention was employed by civil rights activists to draw public attention to their cause. This strategy involved occupying a public space for an extended period of time, such as the Montgomery bus boycott or the Occupy Wall Street movement.
