Gilder Lehrman: America Before Columbus

What Was America Like Before Columbus?

Display the question:

"What do you think North and South America looked like before Columbus arrived in 1492?"

Students individually write three ideas.

Possible responses:

• Small villages
• Large cities
• Forests and farmland
• Trading networks
• Indigenous nations

Partner Discussion (Co-Use)

Students share their ideas with a partner and compare answers.

Together, they create a list of what they believe historians know about pre-Columbian America.

Challenging Historical Assumptions

Introduce Charles C. Mann and his book 1491.

Explain that for many years, historians believed the Americas were sparsely populated before Columbus arrived.

Recent archaeological, environmental, and historical evidence suggests:

• Large populations existed.
• Extensive trade networks existed.
• Advanced agricultural systems were developed.
• Large cities and settlements flourished.

Key Vocabulary

• Indigenous
• Pre-Columbian
• Civilization
• Archaeology
• Population
• Epidemic
• Colonization

Co-Use Activity

Student A reads a vocabulary definition.

Student B explains it in everyday language.

Partners switch roles.

Video Investigation
Students watch selected excerpts from the lecture.

Viewing Questions:

1. What evidence suggests that the Americas were heavily populated?
2. What examples of advanced civilizations does Mann discuss?
3. How did disease affect Indigenous populations?
4. Why did Europeans often believe the land was mostly empty?

Co-Use Activity

Partners share a viewing guide.

• Student A records evidence presented.
• Student B records questions and observations.
• Partners compare notes after each segment.

Discussion

Create a class evidence chart.

Historical Claim                                                     Evidence Presented

Exit Ticket

Answer the following:

1. What was one new fact you learned about the Americas before Columbus?
2. What evidence supports that claim?
3. How did disease affect Indigenous populations?
4. Why is it important to reconsider historical interpretations?

Success Criteria

Students can:

✓ Describe pre-Columbian civilizations.

✓ Cite evidence from the lecture.

✓ Explain how historical interpretations can change.

Then and Now Reflection

Students respond:

"How might history be different if Indigenous civilizations had not experienced widespread disease after European contact?"

Co-Use Activity
Students discuss their responses with a partner before writing.

Partners identify one idea they agree upon and one idea they view differently.
