How to Compare Civilizations on the AP World Exam | 2025 Guide

• Mongols vs Islamic Caliphates → Trade + tolerance.
• China vs Japan → Isolation vs adaptation.
• Aztec vs Inca → Agriculture + empire-building.
• British vs French colonies → Different economic + political structures.
• Industrial Britain vs Meiji Japan → Both industrialized, different timing.

Step 4: Using SPICE-T for Comparison

Always tie your comparisons to SPICE-T themes:

• Social: Gender roles, classes, family structure.
• Political: Leadership, government systems.
• Interaction: Geography, trade, migration.
• Cultural: Religion, art, ideas.
• Economic: Agriculture, industry, trade.
• Technology: Innovations, military power.

Step 5: Essay Strategy for Comparisons

LEQ Example

Prompt: “Compare the causes of empire expansion in TWO regions from 1450–1750.”

• Thesis: Both the Ottoman Empire and Spanish Empire expanded due to military technology, but while Ottomans sought regional dominance, Spain pursued overseas wealth.

DBQ Example

Prompt: “Evaluate the extent to which imperialism in Africa and Asia was similar in the 19th century.”

• Compare documents → both exploited resources, but differed in methods of control.

SAQ Example

Prompt: Identify one similarity and one difference between the Mongol and Islamic empires.

Step 6: Sample Comparisons

Mongols vs Islamic Caliphates

• Similarity: Both supported long-distance trade.
• Difference: Mongols were nomadic conquerors; Caliphates were urban religious states.

China vs Japan (1450–1750)

• Similarity: Both influenced by Confucianism.
• Difference: China remained under Ming/Qing dynasties, while Japan (Tokugawa) isolated.

Aztec vs Inca

• Similarity: Both built tribute-based empires.
• Difference: Aztec = floating gardens (chinampas); Inca = terraced farming.

Step 7: Common Pitfalls in Comparison

• Listing facts without analysis.
• Forgetting reasons for similarities/differences.
• Over-generalizing (e.g., “Both were powerful”).
• Ignoring geography as a key factor.

Always ask: Why were they similar/different?

Step 8: Practice Activity

Take two civilizations and practice:

1. Write one similarity.
2. Write one difference.
3. Explain the reason.

Example: Industrial Britain vs Meiji Japan

• Similarity: Both industrialized rapidly.
• Difference: Britain industrialized first due to coal; Japan borrowed tech after Meiji Restoration.
• Reason: Geography + timing.
