Social movements are significant in political change as they mobilize public support around specific issues, pushing for reform and justice. They can challenge existing power structures and raise awareness of social inequalities or injustices, leading to legislative or cultural shifts. Movements like civil rights, feminism, and climate activism showcase how grassroots efforts can influence public policy and perception. Furthermore, they often utilize modern communication methods to spread their message, gaining traction quickly and connecting with a broader audience, thereby amplifying their impact on political discourse.
