PERIOD 1: 1491–1607
Native Societies & European Exploration
Big Picture
Before European contact, Native American societies were diverse, complex, and
well-established. European exploration was driven by economic gain, religious goals, and
competition between nations. Contact between the Old World and the New World reshaped
societies on both sides of the Atlantic.
Native American Societies (Pre-1491)
● Northeast: Farming, permanent villages, political alliances (Iroquois Confederacy)
● Great Plains: Nomadic lifestyle, buffalo-centered economies
● Southwest: Irrigation systems, pueblos, agriculture
● Mississippi River Valley: Large cities such as Cahokia
, Key idea: Native societies adapted to their environments.
European Motives for Exploration
● Economic: Search for gold, silver, and trade routes
● Religious: Spread of Christianity
● Political: Competition for global power
Columbian Exchange
From the Americas to Europe: corn, potatoes, tomatoes
From Europe/Africa to the Americas: horses, cattle, sugar, smallpox
⚠️ Exam Tip: Disease caused the largest population decline among Native Americans.
PERIOD 2: 1607–1754

economies and cultures. These differences shaped labor systems, social structures, and
relationships with Native Americans.
