APWH · Unit 3— c. 1450 — c. 1750 —

The age of gunpowder.

Ottoman, Safavid, Mughal, Russian, Ming/Qing — and the bureaucracies they ran on.

What you need to know

Five Eurasian land empires expanded between 1450 and 1750, all leaning on cannon and infantry firearms. The Ottomans took Constantinople in 1453; Safavid Persia made Twelver Shiism state religion; Mughal India ruled most of South Asia; Romanov Russia stretched from the Pacific to Poland; Ming-then-Qing China consolidated Inner Asia. They governed diverse peoples through millet-like systems, civil-service exams, and tax-farming—and all eventually faltered against industrializing rivals.

    Empires Expand

    Ottoman, Safavid, Mughal, Russian, Ming/Qing all rise.GOV · TEC
    What to study

    Five major Eurasian land empires expanded between 1450 and 1750, all relying on gunpowder weapons. The Ottoman Empire conquered Constantinople in 1453, then much of southeast Europe, the Levant, and North Africa. Safavid Persia established Twelver Shiism as state religion. Mughals ruled most of South Asia from 1526 forward. Romanov Russia expanded eastward to the Pacific and west into Poland. Ming/Qing China consolidated control over Inner Asia. Common thread: cannon and infantry firearms changed warfare and statecraft.

    Key termsGunpowder empires · Constantinople 1453 · Janissaries · Devshirme · Mehmed II · Suleiman
    Exam focusIdentify common patterns (gunpowder, central bureaucracy, religious legitimation) AND key differences (Sunni vs. Shia, Hindu vs. Muslim subjects).

    Empires: Administration

    How land-based empires governed diverse peoples.GOV · CDI
    What to study

    All five empires faced the same challenge: ruling diverse populations with limited communication technology. Their solutions varied. Ottomans used the millet system (separate religious-legal communities) and devshirme child-levy to recruit Christian boys as Janissaries and administrators. Mughals under Akbar abolished jizya, employed Hindus, and patronized syncretic art. Qing relied on the Confucian civil-service exam plus Manchu military aristocracy. Russia tied serfdom to the state and ennobled service through the Table of Ranks. All used tax-farming, with mixed success.

    Key termsMillet system · Devshirme · Mansabdari · Civil Service Exam · Cossacks · Tax-farming
    Exam focusCompare 2–3 administrative strategies. Be specific (e.g., “the millet system” vs. “they were tolerant”).

    Empires: Belief Systems

    Religious policy and cultural patronage.CDI
    What to study

    Religious policy defined imperial legitimacy. Ottomans were Sunni Muslim but tolerant of Christian and Jewish subjects via the millet system. Safavids made Twelver Shiism the state religion of Persia—creating the Sunni-Shia geopolitical divide that persists today. Mughals oscillated: Akbar created a syncretic court religion; Aurangzeb reimposed jizya and provoked Hindu Maratha resistance. Counter-Reformation Catholicism drove Spanish and Portuguese imperial culture. Each empire used art, architecture, and patronage (Taj Mahal, Süleymaniye, Forbidden City) to project sacred legitimacy.

    Key termsSunni-Shia split · Twelver Shiism · Jizya · Akbar · Aurangzeb · Sikhism · Counter-Reformation
    Exam focusCite specific buildings or works that illustrate religious-political ideology. Don’t generalize about “tolerance.”

    Comparison in Land-Based Empires

    Compare administrative or cultural strategies.GOV · CDI
    What to study

    Strong comparison FRQ topics: succession crises (Ottoman fratricide, Mughal wars of succession, Qing primogeniture); religious policy (Akbar vs. Aurangzeb; Ottoman tolerance vs. Spanish expulsions); economic foundation (timar/iqta land grants vs. mansabdari ranks vs. Manchu banner system). All five empires also had similar weaknesses: tax-farming corruption, succession instability, and a slowness to adapt military technology that left them vulnerable to industrializing rivals in Unit 5.

    Key termsTax-farming · Succession · Religious legitimation · Imperial overstretch
    Exam focusFor “compare” essays: pick TWO specific strategies and explain why each empire adopted what it did. Cause matters.
