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

3.1
Empires Expand
Ottoman, Safavid, Mughal, Russian, Ming/Qing all rise.GOV · TEC
What to studyFive 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 · SuleimanExam focusIdentify common patterns (gunpowder, central bureaucracy, religious legitimation) AND key differences (Sunni vs. Shia, Hindu vs. Muslim subjects).Primary sourceOgier Ghiselin de Busbecq, Turkish Letters (on the Ottoman Empire), 1555 — Fordham Internet History Sourcebooks
The Habsburg ambassador’s observations of Ottoman military and administrative organization — an outsider’s account of how Süleiman’s empire expanded and maintained control.Whose story is missing?“In the month of Ramadan of the year 899, in my twelfth year, I became king. In the first years I was left without a country, without allies, without supplies or soldiers—I had only my desire and a few hundred followers.” — Babur, Baburnama (Memoirs of Babur), written c. 1520s (translated from Chaghatai Turkish)
Babur (1483–1530) wrote the first autobiography in Muslim literature—a frank, detailed memoir of his campaigns to found the Mughal Empire. He documented conquest not as inevitable triumph but as years of failure, displacement, and improvisation. His account shows what empire-building looked like from the inside: the chaos, the contingency, and the human cost that political histories of empire expansion erase. Read the source →

Empires: Administration
How land-based empires governed diverse peoples.GOV · CDI
What to studyAll 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-farmingExam focusCompare 2–3 administrative strategies. Be specific (e.g., “the millet system” vs. “they were tolerant”).Primary sourceAbu’l-Fazl, Akbar-Nama (on Mughal administration), c. 1590 — Fordham Internet History Sourcebooks
Akbar’s court historian describes the Mughal revenue system and administrative structure — a model of how land-based empires extracted resources and governed diverse populations.Whose story is missing?“The Turks received us with kindness and hospitality. We were permitted to live according to our own laws, to worship in our synagogues, and to pursue our trades. Unlike the Christians from whose lands we had been expelled, they did not force us to change our faith.” — Joseph Ha-Kohen, Emek ha-Bacha (Vale of Tears), c. 1558 (translated from Hebrew)
Ha-Kohen (1496–c.1578) was a Jewish physician and historian who documented the expulsion of Jews from Spain (1492), France, and various Italian states—and their welcome in the Ottoman Empire. His comparative account of how different empires governed religious minorities reveals what administrative diversity meant in practice: the Ottoman millet system allowed Jewish, Armenian, and Greek communities to maintain their own courts, schools, and religious institutions in ways that Christian kingdoms did not.

Empires: Belief Systems
Religious policy and cultural patronage.CDI
What to studyReligious 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-ReformationExam focusCite specific buildings or works that illustrate religious-political ideology. Don’t generalize about “tolerance.”Primary sourceMatteo Ricci, journals (on Christianity in Ming China), c. 1609 — Fordham Internet History Sourcebooks
The Jesuit missionary’s account of accommodating Christianity to Confucian culture — illustrating how land-based empires navigated religious diversity and used it strategically.Whose story is missing?“My mind and body dissolved into you, O Lord, the moment you appeared before me. I have no shame left in the world’s eye, no fear of what they say—for I have drunk the cup of your love, and I am drunk with it.” — Mirabai, Bhakti devotional poetry, c. 1498–1547 (translated from Braj Bhasha)
Mirabai was a Rajput princess who rejected royal life and aristocratic convention to become a wandering Bhakti poet-devotee of Krishna. Her songs—sung by low-caste and high-caste women alike across centuries—challenged both caste hierarchy and the gendered constraints that confined elite women. The Bhakti movement created a religious space where women and lower-caste devotees could claim direct spiritual authority that formal religious institutions denied them. Read the source →

Comparison in Land-Based Empires
Compare administrative or cultural strategies.GOV · CDI
What to studyStrong 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 overstretchExam focusFor “compare” essays: pick TWO specific strategies and explain why each empire adopted what it did. Cause matters.Primary sourceOgier Ghiselin de Busbecq, Comparison of Ottoman and European Military, 1555 — Fordham Internet History Sourcebooks
Busbecq’s direct comparison of Ottoman discipline and European disorder is itself a comparative source — useful for analyzing what distinguished successful land-based empire-building across regions.Whose story is missing?“The Turks select from among the Christians the most capable boys, of twelve or fourteen years of age, and convert them to the Turkish faith and customs… I myself was among those who were taken in this way, and I served the Sultan as a janissary for many years.” — Konstantin Mihailović, Memoirs of a Janissary, c. 1490 (translated from Old Serbian)
Mihailović (c. 1430–c.1501) was a Serbian Christian captured by the Ottomans around 1455 during the conquest of Smederevo. He served as a janissary for over a decade before escaping to write this memoir—one of the earliest first-person accounts of the devshirme system from the inside. His comparative observations of Ottoman versus Christian military governance show what the “administration of diverse peoples” looked like for the people being administered. Read the source →
