USA history period 1-5

European exploration in the Americas

State-backed voyages (first Spanish/Portuguese, later French/English/Dutch) that connected Europe to the Americas and initiated sustained contact, conquest, colonization, and trade.

Columbian Exchange

Post-1492 transfer of plants, animals, people, and pathogens between the Eastern and Western Hemispheres, transforming ecosystems, economies, and societies (often unevenly, especially via disease).

Reconquista (1492)

The completion of Spain’s long effort to expel Muslim rule; intensified a crusading spirit and helped link Spanish expansion to Catholic mission.

Ottoman control of land routes

Ottoman dominance over key overland trade routes to Asia, encouraging European states to seek alternative sea routes for Asian goods.

Caravel

A faster, more maneuverable ship design that helped make Atlantic crossings and ocean navigation more reliable.

Lateen sail

Triangular sail design that improved the ability to sail into the wind, supporting longer ocean voyages and return routes.

Tacking

A sailing method used to move against the wind by zigzagging, made more effective by improved sails and rigging.

Compass

Navigation tool that helped sailors determine direction during open-ocean voyages.

Astrolabe/Quadrant

Navigation instruments used to estimate latitude, improving long-distance ocean travel.

Cartography (including portolan charts)

Improved mapmaking; portolan charts helped with coastal navigation and supported more reliable voyages.

Political centralization (Spain)

A strengthened monarchy (especially after the union of major kingdoms) that could fund and organize overseas exploration and empire-building.

Ferdinand of Aragon and Isabella of Castile

Monarchs whose union helped consolidate Spanish power, enabling Spain to finance voyages and pursue overseas competition and Catholic expansion.

Christopher Columbus (1492)

Explorer backed by Spain seeking a westward route to Asia; his voyages opened sustained transatlantic contact that launched wider Spanish exploration and conquest.

A reference point used to study North America before European contact, emphasizing that Indigenous peoples already had complex, diverse societies with established political systems, economies, and diplomacy.

Human-environment interaction

The process by which people adapt to their environment (climate, geography, plants/animals) and also modify it through practices like farming, irrigation, controlled burning, and settlement.

Indigenous nations

Distinct Native political communities with sovereignty and their own identities; a term that highlights that Indigenous groups were not one single society.

Cultural and political diversity (pre-contact North America)

The reality that by 1491 North America contained many different languages, cultures, and forms of government, ranging from small bands to large confederacies and city-based societies.

Three Sisters

An intercropping system of maize (corn), beans, and squash in which the crops support one another, improving nutrition and agricultural productivity.

Controlled burning (cultural burning)

Intentional use of fire to manage landscapes—clearing underbrush, encouraging desired plants, and improving hunting conditions—showing that many environments were actively shaped by Indigenous practices.

Irrigation

A farming technique that channels water to crops, especially important in arid regions like the Southwest to support settled agriculture.

Land tenure

The way land is controlled or “owned” (e.g., communal, seasonal, or use-based systems), often differing from European private-property and deed-based ownership.

Social stratification

A social structure organized into unequal levels (such as elites, commoners, and enslaved people), which in some regions developed due to abundant, storable resources.

Seasonal rounds (seasonal mobility)

Zuni

A Southwest Indigenous people noted (in APUSH context) for settled communities supported by agriculture adapted to arid conditions, often discussed alongside pueblo life.

Mercantilism

An early modern economic theory claiming global wealth was finite and colonies should provide raw materials and markets to strengthen the home country (export more than import).

Navigation Acts

British laws meant to regulate colonial trade to benefit Britain (e.g., using British ships, channeling key goods through British markets, collecting duties, limiting trade with rivals).

Salutary neglect

A period/idea of lax or inconsistent British enforcement of trade regulations, allowing some colonial evasion because the empire remained profitable.

Middle Passage

The transoceanic leg of the transatlantic slave trade in which enslaved Africans were transported to the Americas under horrific, deadly conditions.

Tobacco cultivation

A labor-intensive Chesapeake cash crop that drove plantation expansion and strongly influenced social and political development.

Indentured servitude

A labor system in which workers signed contracts to work for a set number of years in exchange for passage, food, and shelter; common in the 1600s.

Native dependency (early colonization)

The reality that many early European colonies survived only through Native trade, agricultural knowledge, and tactical alliances.

Indigenous agency

The idea that Native nations made strategic choices—using diplomacy, trade, warfare, migration, and coalition-building—to protect their interests rather than acting as passive victims.

Epidemic disease (e.g., smallpox)

Diseases that often spread faster than Europeans themselves, weakening Native communities and reshaping regional political power.

Missionizing

European efforts to convert Native peoples to Christianity and reshape Indigenous life, often paired with pressure to adopt European social and agricultural norms.

Exclusive, permanent land ownership

An English settler land practice emphasizing fenced fields and expansion of town boundaries, often clashing with Native land-use systems.

Shared or seasonal land use

A common Indigenous approach (with regional exceptions) featuring layered rights (hunting/planting/fishing) and diplomacy-based boundaries rather than exclusive ownership.

Jamestown–Powhatan relations

A pattern of trade, uneasy cooperation, and warfare showing that early English survival depended on Native power, but later English stability increased land-driven conflict.

Pequot War (1636–1637)

A New England conflict driven by trade and territorial competition that ended in devastating violence against the Pequot and shifted regional power.
