Answer:
Industrial Revolution
Explanation:
The Industrial Revolution destroyed the old division of society: clergy, nobility and commoners. There was a development of a bourgeoisie, a middle class who engaged in trade and other capitalist ventures. The wealthy bourgeois were factory owners, bankers, mine owners and merchants. Industrialization sharpened the distinctions between the middle class and the labouring class. Factory workers were the newest and most rapidly growing social group.
