, 1. Unit Overview & The Big Picture
Unit 1 covers the shortest timespan of any APUSH unit (1491–1607) but sets up ideas that show up on the exam all
year. If you remember one thing, remember this:
Contact between Europeans, Native Americans, and Africans permanently transformed all three groups —
this is called the Columbian Exchange, and it is the single most important idea in Unit 1.
This unit is typically tested through a handful of multiple-choice questions and occasionally shows up in a Short
Answer Question (SAQ) — it rarely anchors a full DBQ or LEQ on its own, but examples from Unit 1 (like the
encomienda system or the Columbian Exchange) are useful evidence for later essay prompts about colonization, labor
systems, and slavery.
The 3 Things Your Teacher Wants You to Walk Away Knowing:
• Native societies before 1492 were diverse and complex — not a blank slate waiting for Europeans.
• Contact triggered massive, two-way change (Columbian Exchange) — but the impact was wildly unequal, with
Native populations suffering catastrophic losses.
• European colonization was driven by competing empires (Spain first and biggest) with different goals, methods,
and relationships to Native peoples.
2. Key Concepts (Official College Board Framework)
The College Board organizes every period around 2–3 'Key Concepts.' These are the literal blueprint for what can
appear on your exam — memorize the ideas, not just the vocab.
Key Concept 1.1
As Native populations migrated and settled across North America over time, they developed distinct and increasingly
complex societies by adapting to and transforming their diverse environments.
• Environment shaped society: farming (maize) supported dense, complex settlements (Cahokia, Pueblo); arid/plains
regions produced smaller, more mobile groups.
• Native societies were NOT uniform or 'primitive' — they ranged from small kinship bands to large confederacies
with sophisticated political and trade systems.
• Trade networks connected distant Native groups long before Europeans arrived (e.g., goods moving between the
Great Lakes and the Gulf of Mexico).
Key Concept 1.2
Contact among Europeans, Native Americans, and Africans resulted in the Columbian Exchange and significant social,
cultural, and political changes on both sides of the Atlantic Ocean.
• Spain built an empire through conquest (Cortés, Pizarro), extraction of resources (silver, gold), and forced labor
(encomienda system).
• Disease was the single biggest driver of change — demographic collapse of Native populations reshaped power
dynamics across the Americas.
• Competing European justifications for colonization: religious (spreading Christianity, especially post-
Reformation), economic (mercantilism, resource extraction), and political (national prestige, rivalry between
empires).
• The beginnings of racialized slavery and the Atlantic slave trade emerge in this period as Spanish and Portuguese
colonizers turned to enslaved Africans for labor, especially as Native populations collapsed.
