Manifest Destiny: Ideology & ExpansionActivities & Teaching Strategies
Active learning works because Manifest Destiny’s ideology is abstract yet deeply embedded in visual culture and contested narratives. Students need to see how symbols like John Gast’s painting shape belief, then test those beliefs against multiple voices and frames. Moving from image to argument helps students recognize ideology as a tool that persuades as much as it explains.
Learning Objectives
- 1Explain the core beliefs and motivations behind the ideology of Manifest Destiny.
- 2Analyze primary source documents to identify arguments used to justify westward expansion.
- 3Compare and contrast the experiences of white American settlers and Native Americans during westward expansion.
- 4Critique the concept of Manifest Destiny by evaluating its impact on different groups of people.
- 5Synthesize information to construct an argument about the long-term consequences of Manifest Destiny on the United States.

Visual Analysis: John Gast's 'American Progress' (1872)
Students analyze the painting in detail: what is moving east to west, what the allegorical figure of Columbia carries, who is being pushed out of the frame, and what the painting suggests about who benefits from expansion. Groups then compare the painting's message to a map of Native American land loss from 1830 to 1850.
Prepare & details
Explain the core tenets of Manifest Destiny and its appeal to Americans.
Facilitation Tip: During the Visual Analysis, ask students to note every detail in Gast’s painting before interpreting it, to prevent quick assumptions about the artist’s intent.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Perspective-Taking: Three Views on Westward Expansion
Provide three brief primary source excerpts: O'Sullivan's original Manifest Destiny article, a statement from a Mexican official protesting Texas annexation, and a Native leader's account of encroachment on tribal lands. Students identify the values and interests in each source, then discuss whose perspective is centered in most textbooks.
Prepare & details
Analyze how Manifest Destiny justified territorial expansion and displacement of Native Americans.
Facilitation Tip: For Perspective-Taking, assign roles before students read their documents to ensure they engage with the viewpoint rather than just the text.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Structured Discussion: How Does an Ideology Work?
Students answer three questions in writing before discussing: What did Manifest Destiny promise to white American settlers? What did it require them to believe about Native Americans and Mexicans? Who promoted it and what did they gain? The discussion uses evidence to analyze how ideologies function rather than just describing what Manifest Destiny claimed.
Prepare & details
Critique the concept of Manifest Destiny from the perspective of those it displaced.
Facilitation Tip: During the Structured Discussion, keep the question ‘How does an ideology work?’ visible so students connect their examples back to the concept.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Teaching This Topic
Teachers often start with the painting to hook students, but research shows that unpacking ideology requires slow analysis of visual rhetoric and primary texts. Avoid framing Manifest Destiny as inevitable progress; instead, emphasize its contested nature by centering Native and Mexican perspectives. Use structured discussions to move students from observation to critique.
What to Expect
Successful learning looks like students explaining how an image like ‘American Progress’ encodes ideology, and then using primary sources to challenge or refine that interpretation. They should articulate not just what happened during westward expansion, but how the ideology justified it and who resisted it.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Visual Analysis: Students may assume ‘American Progress’ is a neutral historical record.
What to Teach Instead
During Visual Analysis, direct students to reread the painting’s title and the angel’s gaze—ask them to identify what is moving forward and what is being left behind, explicitly naming the ideology behind the composition.
Common MisconceptionDuring Perspective-Taking: Students may believe most Americans at the time fully supported westward expansion.
What to Teach Instead
During Perspective-Taking, after students read their assigned documents, ask each group to identify one piece of evidence in their text that contradicts the idea of universal support, then share with the class.
Common MisconceptionDuring Structured Discussion: Students may reduce Manifest Destiny to a simple desire for land.
What to Teach Instead
During Structured Discussion, challenge students to articulate how the ideology connected land acquisition to racial and religious identity, using quotes from the Gast painting or primary sources as evidence.
Assessment Ideas
After the Structured Discussion, pose the question: ‘Was Manifest Destiny a force for progress or destruction in 19th-century America?’ Ask students to support their answers with specific evidence from the Visual Analysis and Perspective-Taking activities, considering at least two different perspectives.
During the Perspective-Taking activity, provide students with a short excerpt from an 1840s newspaper article promoting westward expansion. Ask them to identify two specific phrases or sentences that reflect the ideology of Manifest Destiny and explain why they chose them within their small groups.
After the Visual Analysis, on an index card, have students write one sentence explaining the primary appeal of Manifest Destiny to Americans in the 1840s based on Gast’s painting. Then, have them write a second sentence describing one negative consequence of this belief for Native Americans, using details from their Perspective-Taking documents.
Extensions & Scaffolding
- Challenge students to redesign Gast’s painting from the perspective of a displaced Native nation or Mexican citizen, writing a 1-paragraph artist’s statement to explain their choices.
- Scaffolding: Provide sentence stems for the Perspective-Taking activity, such as ‘As a [role], I believe westward expansion will… because…’
- Deeper: Have students analyze a modern political speech or advertisement that uses similar language of destiny or inevitability, comparing its rhetorical strategies to 19th-century Manifest Destiny.
