The main significance of the Industrial Revolution for urban life was the rapid urbanization and transformation of society. As industries grew, people flocked to cities for work, leading to the expansion of urban populations. This major shift resulted in the decline of agrarian lifestyles, altering family structures, and creating new social classes such as the industrial working class and the bourgeoisie. While the Revolution brought economic progress and innovation, it also introduced challenges, including overcrowding, poor living conditions, and labor exploitation, sparking social movements that sought to address these issues and improve the quality of urban life.
