Final answer:
During the 1960s, sit-ins, freedom rides, boycotts, protest marches, and civil disobedience were popular forms of nonviolent protest that contributed significantly to the advancement of the civil rights movement and helped lead to the passing of the Civil Rights Act of 1964.
Step-by-step explanation:
The 1960s were a pivotal decade in American history, particularly with respect to the African American civil rights movement. Popular forms of protest during this time included a variety of nonviolent tactics such as sit-ins, carried out famously by students in Greensboro, North Carolina to desegregate lunch counters; freedom rides, which were organized to enforce desegregation in interstate transportation; and boycotts, like the Montgomery Bus Boycott sparked by Rosa Parks' refusal to give up her seat. Other methods of engagement included protest marches and the act of civil disobedience, which were instrumental in driving legislative changes, like the Civil Rights Act of 1964 which banned discrimination based on race and other characteristics. The collective action of these various forms of protest made a significant impact on the fight for civil rights.
