Abstract

The 20th century witnessed profound transformations in global social movements, driven by diverse factors such as political upheaval, economic inequalities, and cultural shifts. This paper offers a historical analysis of collective action, tracing the evolution of social movements from the early part of the century to the contemporary period. It examines the key phases in the development of social movements, including the rise of labor movements, civil rights struggles, feminist movements, anti-colonial resistance, and environmental activism. The paper explores the interplay between global events and local contexts, emphasizing the role of technological innovations, communication strategies, and mobilization techniques that reshaped how collective action was organized and executed. By focusing on case studies from different regions, the paper highlights the mechanisms of solidarity and the strategic uses of media in shaping public opinion and political outcomes. It further examines how social movements were often catalysts for significant policy changes and social reforms. Despite differing ideologies and goals, a common theme that emerges from these movements is the drive for social justice and the quest for equality. The paper concludes by considering the future trajectory of social movements in the 21st century, especially in light of the increasing role of digital technologies in organizing collective action. The ongoing challenges faced by contemporary movements—such as global inequality, environmental crises, and political polarization—suggest that the evolution of social movements remains a crucial area for ongoing academic inquiry.
