The World Turns West

Lesson 4.1 · Unit Launch, Framing the Age of Exploration

For centuries, the Silk Road carried goods, ideas, and disease across Eurasia by land. Then, in 1453, the Ottomans took Constantinople, and Europe's overland route to the riches of Asia closed. What happened next reshaped the entire planet. Welcome to Unit 4.

Learning Targets

Learning Targets and Success Criteria

Build the vocabulary and evidence needed to meet standard 6.2.CE.

Targets

What I will learn

  • I can explain why the closing of overland routes to Asia pushed European nations toward the Atlantic.
  • I can state this unit's overarching inquiry question in my own words.
  • I can preview the major topics this unit will cover: exploration, conquest, exchange, and the Atlantic slave trade.
  • I can identify at least one turning point that will recur across this unit's lessons.
Success Criteria

What success looks like

  • I explain the fall of Constantinople as a turning point using the word catalyst.
  • I restate the overarching inquiry question: did increased global exchange further unite or further divide people?
  • I name at least three topics this unit will study.
  • My exit ticket predicts one way this unit's events might unite people and one way they might divide people.
Standard 6.2.CE

Explain the impact of global exchanges among world civilizations.

Analyze historical turning points to determine long- and short-term causes and effects.
Vocabulary

Pulling twenty lessons into one argument.

These terms will be used throughout the mini-lesson, evidence lab, hands-on activity, journal, and exit challenge.

01 · Concept

Catalyst

An event or development that triggers a much larger chain of change, without which the later events might not have happened.

02 · Question

Overarching Inquiry Question

The central question guiding this unit's study: did increased global exchange further unite or further divide people?

03 · Place

The Atlantic World

The network of connections, trade, conquest, and exchange that linked Europe, West Africa, and the Americas beginning in the late 1400s.

04 · Skill

Turning Point

A moment in history after which the direction of events changes significantly and permanently.

College & Career Connections

Where this shows up in the real world.

History is not just something that happened. It is training for how you will read evidence, weigh sources, and make decisions in a career.

Global Logistics

Mapping Supply Chains

Supply-chain analysts trace how the closing of one trade route forces entire economies to find new paths, precisely the kind of cause-and-effect thinking that opens this unit.

World History Education

Framing a Year of Study

Curriculum designers and teachers build units around a single driving question, the same structure this unit's overarching inquiry question gives your own learning.

Mini-Lesson

Why the Atlantic, Why Now?

One closed door and a handful of new tools sent European sailors into open ocean for the first time in history.

By 1450, the Silk Road that had connected East Asia to Europe for over a thousand years was becoming harder and more expensive to use. When the Ottoman Empire captured Constantinople in 1453, European merchants lost their easiest access to the spices, silk, and other Asian goods that had made fortunes for centuries. Muslim middlemen now controlled the routes Europeans had relied on, and buying from them cut deeply into profits. European monarchs and merchants began asking a new question: was there another way to reach Asia, one that did not require crossing land controlled by rivals?

The answer, it turned out, lay across the Atlantic Ocean. Portugal and Spain, two small kingdoms on the western edge of Europe, were uniquely positioned to test the idea of an all-water route. Both nations had just finished centuries of conflict with Muslim states on the Iberian Peninsula, both had access to the open ocean, and both were hungry for a new source of wealth and religious mission. Over the next two hundred years, their voyages, and the French and English voyages that followed, would connect Europe, West Africa, and the Americas into a single interlocking system now called the Atlantic World.

This unit follows that system from its first tools and voyages, through the conquest of the Aztec and Inca Empires, through the Columbian Exchange that rewired the biology of two hemispheres, to the mercantilist economies and the Transatlantic Slave Trade that powered it all. Across every lesson, you will be building evidence toward one central question: did this new age of global exchange further unite the peoples of the world, or did it further divide them? Keep that question in the back of your mind. By the unit's final lesson, you will need to answer it with evidence.

Non-negotiable routine

Every session this unit: identify the evidence, cite where it came from, connect it to the day's vocabulary, write a one-paragraph explanation.

Guided Practice

Preview the Unit

Practice reading a short historical excerpt and identifying what kind of turning point it describes.

Turning Point Lab
Choose a sample excerpt, then complete the identification protocol.
1 · Identify
What makes this a turning point rather than just an ordinary event?
2 · Connect
Does this excerpt suggest global exchange united people, divided people, or both? Explain.
3 · Compare
How might this event connect to something you already know from earlier units?
4 · Defend
Explain your reasoning using at least one vocabulary term.
Hands-On

Build Your Unit Preview Map

Set up the Evidence Log you will use for the rest of this unit.

1
Label: On your Unit 4 preview map, label the Silk Road, Constantinople, Portugal, Spain, West Africa, and the Americas.
2
Predict: Draw an arrow from Constantinople toward the Atlantic Ocean and write one sentence explaining why.
3
Set up: Create the first row of your Evidence Log with today's date and the topic 'Unit Launch.'
4
Commit: Write a one-sentence prediction answering the overarching inquiry question, to be revisited in Lesson 4.25.
Required

Evidence Log: Entry 1

Write your first prediction: do you think increased global exchange in this unit will further unite people or further divide them? Explain your initial thinking, knowing you will revisit this answer at the end of the unit.
