Period 1 — Major Ideas & Events (1491–1607)
MAYANS — c. 250–900 A.D. / Classic period c. 250–900
Description/Significance:
Developed a sophisticated civilization in Mesoamerica, especially the Yucatán Peninsula and present-day Guatemala and Belize.
Developed a written language, advanced mathematical system, accurate calendar, astronomy, trade networks, and impressive cities.
Their civilization was already declining by the time Europeans arrived, but Maya peoples and communities still existed.
Significance: Shows that complex civilizations existed in the Americas long before European arrival and challenges the idea that Europeans “discovered” an empty or uncivilized continent.
Brinkley emphasizes the Maya's written language, numerical system, calendar, agricultural system, and trade networks.
AZTECS / MEXICA — c. 1300–1521
Description/Significance:
The people commonly called the Aztecs called themselves Mexica.
Established Tenochtitlán around 1300 on an island in a lake in central Mexico.
Built a large empire through military conquest and tribute.
Tenochtitlán had aqueducts, schools, public buildings, an organized military, and a large population.
Significance: The Aztec/Mexica Empire was one of the major civilizations encountered by the Spanish. Its conquest demonstrates how European disease, Native alliances, and Spanish military advantages helped Europeans defeat powerful American societies.
Brinkley notes that Tenochtitlán could have had around 100,000 people by 1500 and that Mexica control depended heavily on military power and tribute.
INCAS — c. 1400s–1530s
Description/Significance:
Developed the largest empire in the Americas, centered in the Andes of western South America.
Began as a small tribe around Cuzco and expanded rapidly under Pachacuti.
Controlled territory stretching almost 2,000 miles.
Used administrative systems and a huge network of paved roads to govern their empire.
Significance: Like the Aztecs, the Incas demonstrate the complexity of pre-Columbian American civilizations. Their conquest by Pizarro shows the devastating effects of European conquest and disease.
Brinkley specifically describes the Inca Empire as the largest empire in the Americas and highlights Pachacuti's expansion and road system.
MAIZE (CORN)
Description/Significance:
One of the most important crops developed and cultivated by Native Americans.
Along with beans and squash, maize supported agricultural communities.
Farming allowed people to become more sedentary, creating permanent settlements.
Significance: Agriculture helped make larger and more complex Native American societies possible.
Brinkley states that farming required people to stay in one place and that maize was the most important crop throughout much of the Americas.
How did Native American language differ from Europeans?
Answer:
Native Americans did not share one common language.
There were many different language groups, including Algonquian, Iroquoian, and Muskogean.
Europeans often incorrectly treated Native Americans as if they were one people, calling them all “Indians.”
Significance: The enormous linguistic diversity shows that North America contained many distinct societies and cultures before European colonization.
Brinkley explains that many eastern tribes shared linguistic roots but belonged to different language groups and did not think of themselves as one civilization.
NATIVE AMERICAN REGIONS
Southwest Settlements
Description/Significance:
Included peoples such as the Pueblos.
Built permanent settlements using stone and adobe.
Developed large irrigation systems because of the dry environment.
Settlements such as Chaco Canyon became centers of trade, crafts, religion, and government.
Significance: Environment strongly influenced Native American economic and social structures.
Northwest Settlements
Description/Significance:
Rich in natural resources, especially salmon.
Many societies established permanent coastal settlements.
Fishing was a major part of their economy.
Competition sometimes occurred over access to resources.
Significance: Shows that agriculture was not necessary for permanent settlements; abundant natural resources could support complex communities.
Great Plains
Description/Significance:
Many groups practiced sedentary farming, especially growing corn and other grains.
Some groups were nomadic and hunted buffalo.
Important: Large-scale buffalo hunting did not become dominant until Europeans introduced horses in the 1700s.
Significance: The horse later dramatically changed Plains societies, demonstrating how European contact transformed Native American life.
Midwest Settlements
Description/Significance:
Included peoples associated with the Mississippi River Valley and Mississippian cultures.
Relied heavily on agriculture, particularly corn.
Developed permanent settlements and extensive trade networks.
Cahokia became a major urban and trading center.
Significance: Demonstrates that sophisticated urban societies existed in North America before Europeans arrived.
Brinkley describes Cahokia as having reached a population of about 40,000 around A.D. 1200.
Northeast Settlements
Description/Significance:
Included Woodland peoples, Algonquian-speaking groups, and Iroquoian peoples.
Had abundant forests, rivers, and other resources.
Many practiced farming, hunting, gathering, and fishing simultaneously.
The Iroquois included the Seneca, Cayuga, Onondaga, Oneida, and Mohawk.
Significance: Native societies adapted their economies to their environments and developed very different political and social structures.
Atlantic Seaboard Settlements
Description/Significance:
Included many Algonquian, Iroquoian, and Muskogean-speaking peoples.
Used a combination of agriculture, hunting, fishing, and gathering.
Coastal and river environments provided abundant resources.
Significance: These were the Native societies that later encountered English colonists, making this region especially important to the development of British North America.
Brinkley identifies Algonquian peoples as dominant along much of the Atlantic seaboard.
How did improvements in technology during the Renaissance make European expansion possible?
Answer:
Improvements in navigation and shipbuilding made long-distance ocean travel more practical.
Better ships allowed Europeans to travel farther into the Atlantic.
Improved navigation helped sailors find and follow new routes.
European monarchies became powerful enough to finance expensive voyages.
Significance: Technological developments combined with economic and political changes to make European overseas expansion possible.
Brinkley directly connects advances in navigation and shipbuilding with the growth of European exploration.
Uniting of Spain under Ferdinand and Isabella — 1469
Description/Significance:
Ferdinand of Aragon and Isabella of Castile married in 1469, linking the two major Spanish kingdoms.
Their monarchy became increasingly centralized and powerful.
They completed the conquest of Granada in 1492, ending Muslim rule in most of Spain.
They sponsored Christopher Columbus's voyage.
Significance: A stronger, unified Spain had the resources and political authority to finance overseas exploration and colonization.
Protestant Reformation — early 1500s
Description/Significance:
Began in 1517, when Martin Luther challenged Catholic practices and authority.
Led to the creation of Protestant churches and religious divisions throughout Europe.
Increased competition between Catholic and Protestant powers.
Significance: Religious competition became another motivation for European colonization, particularly as Spain sought to spread Catholicism.
Brinkley places Luther's challenge in 1517 in its timeline.
What new routes did European powers attempt to travel? Why?
Answer:
Europeans wanted a direct ocean route to Asia.
They wanted access to Asian spices, fabrics, dyes, and other valuable goods.
Overland trade routes were difficult and expensive, and European powers wanted to bypass intermediaries.
Portugal explored around Africa toward India.
Spain attempted to reach Asia by sailing west across the Atlantic.
Significance: The search for Asian trade routes accidentally led Europeans to establish permanent connections between Europe, Africa, and the Americas.
Brinkley specifically identifies the desire for a faster, safer sea route to Asia as a major motivation for exploration.
Where did the slave trade originate? Why? — 15th century
Important correction: The African slave trade did not originate in the 15th century.
According to Brinkley:
West Africans had been selling enslaved people to Mediterranean traders as early as the 8th century.
Portuguese explorers began purchasing enslaved Africans during their exploration of the African coast in the 15th century.
The trade expanded dramatically in the 16th century because of European demand for labor, especially for sugar production.
Significance: European colonization transformed an existing slave trade into a much larger Atlantic system.
Brinkley explicitly states that African slave trading existed centuries before European colonization of the Americas.
How did Africans attempt to resist slavery?
Answer:
Africans resisted through rebellion, escape, and opposition to capture and enslavement.
African states sometimes fought one another partly because Europeans created a growing demand for enslaved people.
People resisted European control in many ways, although records often make the full extent difficult to determine.
Significance: Africans were not passive victims; they actively resisted enslavement and European domination.
CHRISTOPHER COLUMBUS — 1492
Description/Significance:
Columbus sailed west from Spain in 1492 seeking a route to Asia.
He reached the Bahamas/Caribbean, believing initially that he had reached islands near Asia.
His voyages led to permanent European exploration and colonization of the Americas.
Significance: Columbus's voyages initiated sustained contact among Europe, the Americas, and Africa, beginning the enormous demographic, economic, biological, and cultural changes of the Columbian Exchange.
Brinkley emphasizes that Columbus did not actually “discover” the Americas because millions of people were already living there.
What did Columbus's voyages bring about for the first time in history?
Answer:
Sustained contact and exchange among the peoples of Europe, Africa, and the Americas.
This created the Atlantic World and produced massive exchanges of:
People
Plants
Animals
Diseases
Goods
Ideas
Cultures
Significance: This is one of the central ideas of APUSH Period 1.
Brinkley describes the Atlantic World as connecting Europe, the Americas, and Africa through migration, commerce, slavery, and religion.
COLUMBIAN EXCHANGE
Description/Significance:
Exchange of plants, animals, diseases, people, and cultures between the Old World and New World following European contact.
From Americas to Europe: maize, potatoes, other crops.
From Europe to Americas: horses, cattle, pigs, sheep, wheat, sugar, and diseases.
The most devastating part for Native Americans was the introduction of European diseases, especially smallpox.
Significance: Disease caused enormous Native population losses, while new crops and animals transformed societies on both sides of the Atlantic.
Brinkley calls European disease one of the most profound consequences of the exchange.
LINE OF DEMARCATION — 1493
Description/Significance:
A papal decree drew a dividing line through the Atlantic assigning newly claimed lands to Spain or Portugal.
Spain received lands west of the line; Portugal received lands to the east.
Significance: Demonstrates the connection between European exploration and Catholic religious authority.
Brinkley's timeline dates the papal division to 1494-era Spanish-Portuguese claims.
TREATY OF TORDESILLAS — 1494
Description/Significance:
Spain and Portugal agreed to move the dividing line established by the pope.
Portugal gained the territory that became Brazil.
Spain gained most of the rest of the Americas.
Significance: Shows how European powers attempted to divide the New World among themselves without Native Americans having any say.
Brinkley notes that Portugal received what became Brazil while Spain claimed most of the rest of the New World.
VASCO NÚÑEZ DE BALBOA — 1513
Description/Significance:
Crossed the Isthmus of Panama.
Became the first known European to see the Pacific Ocean from the Americas.
Significance: Proved that another enormous ocean existed west of the Americas and encouraged Europeans to search for a route across the Pacific to Asia.
FERDINAND MAGELLAN — 1519–1522
Description/Significance:
Portuguese explorer sailing for Spain.
Found the strait at the southern tip of South America now called the Strait of Magellan.
His expedition crossed the Pacific.
Magellan died in the Philippines, but his crew completed the first known circumnavigation of the globe in 1522.
Significance: Demonstrated the global scale of European exploration and connected the Americas to the Pacific and Asia.
HERNÁN CORTÉS — 1518–1521
Description/Significance:
Spanish conquistador who invaded the Aztec/Mexica Empire.
Arrived in Mexico with a relatively small force.
Faced resistance from the Aztecs but gained assistance from Native groups who opposed Aztec rule.
Smallpox devastated the Aztec population.
Cortés captured Tenochtitlán in 1521.
Significance: The fall of the Aztec Empire expanded Spanish power in the Americas and demonstrates how disease and Native alliances helped Spanish conquest.
FRANCISCO PIZARRO — 1532–1538
Description/Significance:
Spanish conquistador who invaded the Inca Empire in South America.
Conquered the Inca Empire by the late 1530s.
Significance: Spanish conquest destroyed another major American empire and expanded Spain's control over South America.
Brinkley dates the conquest to the 1530s, with the Inca Empire conquered by 1538.
ENCOMIENDA SYSTEM
Description/Significance:
Spanish system that gave colonists the right to demand labor and tribute from Native Americans.
Native people became a major source of labor for Spanish agriculture, mining, and other economic activities.
Often became extremely exploitative.
Significance: Shows that Spanish colonization depended heavily on Native labor and contributed to the exploitation and population decline of Native Americans.
Brinkley describes encomiendas as licenses to exact labor and tribute from Native peoples.
ASIENTO SYSTEM
Description/Significance:
A Spanish system/contract allowing merchants to supply enslaved Africans to Spanish colonies.
Helped Spain obtain the labor it needed after Native populations declined.
Significance: Connected European colonization, African slavery, and the American colonial economy.
Brinkley explains that European settlers began importing Africans as early as 1502 because disease and war had reduced the Native labor force.
JOHN CABOT — 1497
Description/Significance:
Genoese explorer sailing for England's Henry VII.
Explored the northeastern coast of North America.
England used his voyage to establish a claim in North America.
Significance: Began England's involvement in North American exploration, although serious English colonization did not begin for nearly another century.
Why did England not immediately follow up Cabot's discoveries?
Answer:
England was dealing with major internal political, religious, and economic problems.
England needed to become more politically and economically stable before undertaking major colonization.
Its economy was undergoing major changes, including the enclosure movement.
Significance: European colonization depended not only on geographic discovery but also on conditions within the European country itself.
Brinkley specifically explains that nearly a century passed before England made serious colonization efforts because England itself was undergoing major transformation.
SIR FRANCIS DRAKE — 1577–1580
Description/Significance:
English privateer/explorer.
Circumnavigated the globe.
Raided Spanish possessions and ships.
Significance: Demonstrated England's growing challenge to Spanish dominance and helped increase English interest in overseas expansion.
Brinkley's exploration map dates Drake's voyage to 1577–1580.
SIR WALTER RALEIGH & ROANOKE — 1587
Description/Significance:
Raleigh sponsored English attempts to establish colonies.
The Roanoke colony was established in 1587.
The settlers eventually disappeared, earning it the nickname “Lost Colony.”
Significance: One of England's earliest attempts at permanent colonization and a precursor to the later successful English settlements.
Brinkley dates the “Lost Colony” to 1587.
GIOVANNI DA VERRAZANO — 1524
Description/Significance:
Italian explorer sailing for France.
Explored the Atlantic coast of North America.
Searched for a route to Asia through North America.
Significance: Helped establish French claims and knowledge of the North American coastline.
Brinkley's exploration map dates Verrazano's expedition to 1524.
JACQUES CARTIER — 1534–1542
Description/Significance:
French explorer who explored the St. Lawrence River region.
Claimed territory for France.
Searched for a Northwest Passage to Asia.
Significance: His voyages laid groundwork for French colonization in Canada.
Brinkley's map places Cartier's exploration in 1534–1535.
SAMUEL DE CHAMPLAIN — 1608
Description/Significance:
French explorer and colonizer.
Founded Quebec in 1608.
Considered the “Father of New France.”
Built relationships and alliances with Native peoples.
Significance: Quebec became the foundation of France's permanent North American empire.
Brinkley's timeline identifies 1608 as the establishment of Quebec, France's first permanent settlement in America.
LOUIS JOLLIET & FATHER JACQUES MARQUETTE — 1673
Description/Significance:
Explored the Mississippi River and surrounding areas.
Their expedition increased French knowledge of the interior of North America.
Significance: Helped France expand its claims and influence into the interior of the continent.
ROBERT DE LA SALLE — 1682
Description/Significance:
Explored the Mississippi River to its mouth.
Claimed the Mississippi River basin for France, naming the territory Louisiana.
Significance: Expanded French territorial claims across the interior and strengthened France's North American empire.
HENRY HUDSON — 1609
Description/Significance:
English explorer working for the Dutch.
Explored the river that became the Hudson River.
Searched for a Northwest Passage to Asia.
His voyage helped the Dutch establish claims in the region.
Significance: Contributed to the development of New Netherland.
CALIFORNIA — 1769–1784
Description/Significance:
Spain expanded its settlements and missions into California beginning in 1769.
Spanish missionaries established a chain of missions.
Significance: Extended Spanish control farther north along the Pacific coast and expanded Catholic missionary activity.
Important: This is outside Period 1's 1491–1607 timeframe, but it is included on your teacher's sheet, so know it as a later development.
How did Spanish settlers treat Native Americans?
Answer:
Spanish settlers:
Used Native Americans as a major labor force.
Forced Native people to provide labor and tribute through systems such as the encomienda.
Attempted to convert Native Americans to Catholicism.
Seized land and exploited Native labor.
Intermarried with Native peoples more frequently than English colonists later did.
Created a racial hierarchy with Spaniards at the top and Native Americans at the bottom.
Native populations were devastated by disease, warfare, and exploitation.
However, Spanish-Native relationships were complicated. There was also trade, intermarriage, cultural exchange, and Native resistance.
BARTOLOMÉ DE LAS CASAS — 1484–1566
Description/Significance:
Spanish priest who strongly criticized the mistreatment of Native Americans.
Argued that Native Americans were rational human beings capable of understanding Christianity.
Opposed the brutal exploitation of Native peoples.
Significance: Became one of the most important critics of Spanish colonial abuses and helped force Europeans to debate the morality of conquest.
Brinkley's chapter includes Las Casas's account of Spanish treatment of Native people as a primary source.
VALLADOLID DEBATE — 1550–1551
Description/Significance:
Debate in Spain over whether Native Americans were fully human and capable of self-government and Christianity.
Bartolomé de Las Casas argued that Native Americans were rational people who should not be violently conquered.
Juan Ginés de Sepúlveda argued that Spanish conquest and domination were justified.
Significance: One of the major early European debates over the morality and justification of imperialism and treatment of Indigenous peoples.
How did English settlers treat Native Americans?
Answer:
English settlers generally sought to establish permanent European communities rather than simply rule over existing Native populations.
They were more likely than the Spanish to maintain separation between Europeans and Native Americans.
Competition over land increasingly produced conflict.
Native peoples were pushed off their lands as English settlements expanded.
Significance: This created a very different colonial model from Spanish America: the English sought to build a largely European society rather than rule a much larger Native population.
Brinkley specifically contrasts English colonization with Spanish colonization, noting that English, Dutch, and French colonies focused on permanent settlement and family life.
How did French settlers treat Native Americans?
Answer:
French colonists generally had smaller populations and focused heavily on trade, especially the fur trade.
They often formed alliances with Native American groups.
French missionaries attempted to convert Native peoples to Christianity.
French settlers were generally more willing than English colonists to live and intermarry with Native peoples.
Significance: French colonization depended more heavily on Native alliances and trade because France had fewer settlers than England.
How did Native Americans react to European settlement?
Answer:
Native Americans responded in many different ways:
Resistance: fought Europeans and resisted the loss of land and independence.
Alliances: formed partnerships with Europeans against rival Native groups.
Trade: exchanged goods and resources with Europeans.
Adaptation: adopted European technologies, animals, and crops.
Conversion: some converted to Christianity.
Migration: some moved away from areas of European settlement.
Rebellion: revolted against European control, such as the Pueblo Revolt of 1680.
Intermarriage: some Native people married Europeans and formed mixed communities.
Most important APUSH point: Native Americans were not simply passive victims. They made strategic choices, resisted, adapted, traded, allied, and sometimes fought Europeans. Brinkley emphasizes that Native peoples continued to influence European societies even after Europeans gained political control.
⭐ The BIG Period 1 connections to memorize
If your teacher tests the Key Concepts, these are the connections I would put a ⭐ next to:
1. Environment → Native American diversity
Different environments produced different economies and societies: Pueblo irrigation, Northwest fishing, Plains farming/hunting, Eastern Woodland agriculture/hunting/fishing.
2. Maize → permanent settlements → complex societies
Agriculture allowed people to settle permanently, supporting larger civilizations such as the Maya, Mexica, Inca, and Mississippian societies.
3. Europe → exploration → Columbian Exchange
European technological improvements + desire for Asian trade + stronger monarchies → exploration → sustained Atlantic contact.
4. Columbian Exchange → disease = catastrophic Native population decline
Smallpox, measles, influenza, etc. devastated Native populations that lacked immunity.
5. Spanish conquest = disease + weapons + Native alliances
Cortés did not defeat the Aztecs simply because “Spain had better weapons.” Disease and alliances with Native enemies of the Aztecs were enormously important.
6. Spain vs. England vs. France
🇪🇸 Spain: conquest + gold/silver + Catholic conversion + Native labor
🇬🇧 England: permanent settlement + families + land acquisition
🇫🇷 France: smaller settlements + fur trade + Native alliances
7. Atlantic World = Europe + Africa + Americas
The development of the Americas cannot be understood as just European vs. Native American. African peoples, slavery, commerce, migration, and culture were central to the creation of the Atlantic World.
8. Native Americans had agency.
They resisted, negotiated, traded, allied, adapted, and sometimes incorporated European practices into their societies. Their influence did not disappear with European colonization.
