What took the lead in organizing resistance to injustice during the 1960s?

During the 1960s, the Civil Rights Movement emerged as a leading force in organizing resistance to injustice, particularly against racial discrimination and segregation in the United States. Grassroots organizations like the Student Nonviolent Coordinating Committee (SNCC) and the Southern Christian Leadership Conference (SCLC) mobilized protests, sit-ins, and marches, with influential leaders such as Martin Luther King Jr. advocating for nonviolent resistance. This period also saw the rise of other social movements, including those advocating for women's rights and anti-war sentiments, contributing to a broader struggle for justice and equality.
