Final answer:
Cesar Chavez is advocating for the use of nonviolent protest methods such as marches and civil disobedience, similar to those used in the African American Civil Rights Movement, to effect social change.
Step-by-step explanation:
When Cesar Chavez refers to using people power that vanquished injustice in Montgomery, Selma, and Birmingham, he is encouraging the use of nonviolent protest and civil disobedience. Chavez is drawing inspiration from the African American Civil Rights Movement, particularly the successful tactics of marches, boycotts, sit-ins, and rallies that were instrumental in changing unfair laws and societal norms without resorting to violence.
These strategies, exemplified by leaders like Martin Luther King Jr. and fuelled by popular sovereignty, proved essential in securing significant legislative milestones like the Civil Rights Act of 1964 and the Voting Rights Act of 1965. By citing these events, Chavez is making an inference to the effectiveness of grassroots mobilization and public demonstrations in creating social change.
