The First Industrial Revolution primarily altered Western society by causing which major sociological shift?

💡 Explanation:

The Industrial Revolution's creation of factory systems and the resultant mass migration for work led to a profound demographic and social shift from rural/agrarian life to urban centers. This process established distinct social classes—primarily the industrial bourgeoisie (capital owners) and the proletariat (wage laborers)—which fundamentally reorganized society along class lines, supplanting the older feudal/estate systems.
