The significance of the Industrial Revolution in social structure was profound, as it transformed societies from agrarian economies to industrialized, urban ones. Beginning in the late 18th century, advancements in technology and machinery revolutionized production processes. This shift led to the rise of factory work and mass production, contributing to urbanization as people moved to cities for jobs. Social hierarchies changed, with the emergence of a distinct working class alongside a more affluent industrial capitalist class, reshaping labor dynamics and contributing to the development of labor rights movements.
