This document discusses class and caste systems in ancient China, India, and Rome. In China, society was divided into elite officials, landlords, peasants, and merchants. The civil service was open to all males but favored the wealthy. In India, the rigid caste system divided society into hereditary social groups based on occupation. The system justified social inequality through Hindu concepts. In Rome, slavery was widespread and the backbone of the economy, with slaves making up over 30% of the population in some areas. Resistance was generally nonviolent but the rebellion led by Spartacus showed the potential for open revolt. Overall, the document examines how different societies organized and stratified social class and hierarchies.
