AP World Unit 4 Review: 1450-1750

European transoceanic voyaging was made possible by a combination of borrowed and adapted technologies. The compass came from China via the Islamic world; the lateen sail came from Arab and Indian Ocean sailors; astronomical charts drew on classical and Islamic astronomy. Europeans combined these with new ship designs to cross open oceans.

• Caravel: A small, maneuverable Portuguese ship with lateen sails that could sail against the wind and navigate shallow coastal waters, ideal for exploring African coastlines.
• Carrack: A larger, sturdier ship capable of carrying heavy cargo across open oceans, used by Portuguese and Spanish for long-distance trade voyages.
• Fluyt: A Dutch cargo ship with a large hold and small crew requirement, which lowered shipping costs and gave the Dutch a commercial advantage in the 17th century.
• Lateen sail: A triangular sail borrowed from Indian Ocean and Arab sailors that allowed ships to sail at angles to the wind, enabling more flexible ocean navigation.
• Cross-cultural diffusion: The process by which knowledge and technology from Classical, Islamic, and Asian sources spread to Europe and enabled new maritime capabilities.

European states sponsored transoceanic voyages primarily for economic reasons: to access Asian spices and goods directly without paying Muslim or Italian intermediaries. Religious motives, including spreading Christianity, and political rivalry between states also drove expansion. Each major European power pursued a distinct strategy.

• Portuguese trading-post empire: Portugal established a network of fortified ports along African and Asian coastlines to control Indian Ocean trade rather than colonizing large territories.
• Spanish Atlantic expansion: Spain sponsored Columbus in 1492 and subsequent voyages, leading to colonization of the Americas and eventually the Pacific crossing by Magellan's expedition.
• Northern Atlantic crossings: England, France, and the Dutch sponsored voyages across the northern Atlantic, often seeking alternative routes to Asia, leading to colonization of North America.
• State sponsorship: Monarchs funded and authorized voyages in exchange for a share of profits and new territories, making exploration a state enterprise rather than a purely private one.

The Columbian Exchange was the transfer of plants, animals, diseases, and people between the Eastern and Western Hemispheres after 1492. Its effects were asymmetric: new food crops like maize and potatoes boosted populations in Afro-Eurasia over time, while Old World diseases like smallpox and measles caused catastrophic population loss among Indigenous peoples in the Americas.

• Disease transfer: Smallpox, measles, and malaria, along with disease vectors like mosquitoes and rats, moved from the Eastern Hemisphere to the Americas, where Indigenous populations had no immunity, causing massive demographic collapse.
• American food crops: Maize, potatoes, and other American crops became staple foods in Europe, Africa, and Asia, supporting population growth in those regions over the following centuries.
• Afro-Eurasian crops and animals: Europeans brought wheat, sugar, horses, and cattle to the Americas, transforming American agriculture and enabling plantation economies.
• Plantation economy: Cash crops like sugar were grown on large plantations in the Americas using coerced labor, primarily enslaved Africans, and exported to European and Middle Eastern markets.
• African Diaspora: The forced movement of millions of enslaved Africans to the Americas through the Atlantic slave trade created African-descended communities across the Western Hemisphere.

Between 1450 and 1750, European states built maritime empires by establishing trading posts in Africa and Asia and colonies in the Americas. These empires introduced new labor systems in the Americas while disrupting and reshaping existing trade networks. African states like the Asante and Kongo grew in influence through participation in Atlantic trade, though the slave trade ultimately destabilized many African societies.

• Encomienda system: A Spanish colonial labor system granting settlers the right to extract labor and tribute from Indigenous peoples in exchange for supposed protection and religious instruction.
• Chattel slavery: A form of slavery in which enslaved people are treated as permanent, inheritable property, introduced in the Americas to supply labor for plantations after Indigenous populations declined.
• Incan mit'a: An existing Andean labor obligation system that Spanish colonizers adapted and intensified to extract labor for silver mines like Potosi.
• Isolationist trade policies: Ming China and Tokugawa Japan restricted European trade to limit cultural and economic disruption, with Japan confining Dutch traders to the island of Dejima.
• Asante and Kongo: West and Central African states that grew in political influence through participation in Atlantic trade networks, though the slave trade eventually caused demographic and political damage.

European rulers used mercantilist policies and joint-stock companies to finance, expand, and control their maritime empires. The global flow of silver, especially from Spanish American mines at Potosi, connected the Atlantic and Asian economies. The Atlantic trading system moved goods, silver, and enslaved people, while the mixing of African, American, and European peoples produced cultural synthesis and syncretic religious practices.

• Mercantilism: An economic theory holding that national wealth depends on accumulating gold and silver through a favorable balance of trade, used by European rulers to justify colonial extraction and trade monopolies.
• Joint-stock companies: Business entities like the Dutch East India Company (VOC) and British East India Company (EIC) that pooled investor capital to fund expensive overseas trade and colonization, spreading financial risk.
• Global silver trade: Silver mined in Spanish America flowed across the Atlantic to Europe and then to Asia, especially China, which demanded silver for tax payments, linking the world's economies.
• Atlantic trading system: The network connecting Europe, Africa, and the Americas through the movement of manufactured goods to Africa, enslaved people to the Americas, and raw materials and cash crops back to Europe.
• Cultural synthesis: The blending of African, Indigenous American, and European cultural elements in the Americas, visible in syncretic religions, languages, and social practices.

As states expanded and centralized power, they faced resistance from a wide range of groups: Indigenous peoples, peasants, nobles, and enslaved people. Resistance took many forms, from armed revolt to the establishment of independent communities. The AP exam expects you to distinguish internal challenges (from within a state) from external ones (from outside or subject peoples).

• Pueblo Revolt (1680): An uprising by Pueblo peoples in present-day New Mexico against Spanish colonial rule, temporarily driving Spanish settlers out of the region.
• Maroon societies: Communities of escaped enslaved people in the Caribbean and Brazil who established independent settlements and resisted recapture, representing organized collective resistance to slavery.
• Fronde: A series of civil wars in 17th-century France in which nobles and the Paris parlement resisted royal centralization under Cardinal Mazarin and the young Louis XIV.
• Ana Nzinga: Ruler of Ndongo and Matamba in Central Africa who organized military resistance against Portuguese colonial expansion and the slave trade in the 17th century.
• Metacom's War: Also called King Philip's War, a conflict from 1675 to 1678 in which a coalition of Indigenous peoples in New England fought against English colonial expansion.

Global trade and imperial conquest reshaped social hierarchies worldwide. Some empires like the Mughals and Ottomans accommodated ethnic and religious diversity to strengthen their rule. Others, like Spain in the Americas, created rigid racial hierarchies. New elites emerged, and existing elites like Russian boyars and European nobility faced challenges from increasingly powerful monarchs.

• Casta system: A racial hierarchy established in colonial Spanish America that categorized people by ancestry, including peninsulares, creoles, mestizos, mulattoes, and Indigenous and African peoples, determining legal rights and social status.
• Qing Dynasty transition: The Manchu conquest of China and establishment of the Qing Dynasty created new political elites while requiring Han Chinese to adopt certain Manchu practices, reshaping social hierarchies.
• Mughal and Ottoman accommodation: Both empires incorporated diverse ethnic and religious groups into administrative and military roles, using diversity as a source of strength rather than suppressing it entirely.
• Expulsion of Jews from Spain: In 1492, Spain expelled its Jewish population, exemplifying how some states suppressed religious minorities rather than accommodating them, in contrast to the Mughal and Ottoman approaches.
• Boyar class: Russian nobles whose power fluctuated as tsars like Ivan the Terrible and later Peter the Great sought to centralize authority and limit aristocratic independence.

Topic 4.8 asks you to synthesize the whole unit by identifying what changed and what stayed the same. Agriculture remained the foundation of most economies, but where it was practiced, who performed the labor, and what crops were grown all shifted dramatically. Coerced labor persisted and intensified. New social elites emerged alongside old ones. The demand for raw materials and finished goods drove environmental change and labor intensification across the globe.

• Continuity in agriculture: Despite major disruptions, agriculture remained the primary economic activity worldwide through 1750, with most people still working as peasants or farmers.
• Intensification of coerced labor: Growing global demand for cash crops and raw materials increased the use of enslaved and coerced labor, expanding the Atlantic slave trade and colonial labor systems.
• New social hierarchies: Imperial conquest and global trade created new elites in the Americas, China, and elsewhere, while also producing new subordinated groups defined by race and colonial status.
• Environmental change: The introduction of new crops, animals, and farming practices transformed landscapes in the Americas and elsewhere, with plantation agriculture clearing forests and altering ecosystems.
