Notes on US Territorial Expansion, Mission California, and the Marshall Trilogy

Context and Chapter Focus

• The chapter centers on US westward territorial expansion and how indigenous nations and the decline of the Spanish empire shape early US foreign policy and federal power.
• Key terms introduced: westward territorial expansion, manifest destiny, the Marshall Trilogy, and the Monroe Doctrine.
• Central questions:
  • How did Indigenous groups shape early US foreign policy?
  • How did Indigenous nations influence the development of federal government and its power?
  • Why is the Marshall Trilogy pivotal for federal vs. state authority in Indian law?
  • How does the US begin to consolidate power across North America during this period?
• The discussion connects to next week’s focus on the Mexican–American War and the Treaty of Guadalupe Hidalgo.

The Decline of the Spanish Empire and Early Colonization (Late 1700s - Early 1800s)

• The chapter treats the decline of the Spanish Empire as a driving force behind US expansion and the emergence of a hemispheric US power.
• Reading emphasizes the interaction between imperial decline, settler expansion, Indigenous resistance, and evolving federal authority.

Spanish Missions in California: Context, Goals, and Impact (Starting 1769)

• Spain officially occupies California in 1769, later than other territories in the Americas, to deter foreign intervention amid a declining empire.
• Mission system established by Franciscan friars led by Junípero Serra along the California coast.
• Stated goals of the missions:
  • Convert Indigenous populations to Christianity.
  • Create new Spanish subjects loyal to the Spanish Crown in the Americas through missionization.
• Mission infrastructure was built and maintained by Indigenous labor; Indigenous peoples provided the labor to construct and sustain the missions.
• The mission system represents Spain’s last territorial efforts to maintain control as its empire waned.
• Demographic impact: Indigenous California population declined dramatically over roughly a century:
  • Before missionization: approximately 310,000 native Californians.
  • About 80 years later: roughly 150,000 by 1846 (start of the Mexican–American War).
  • By 1873: about 30,000.
• Geographic footprint and modern toponymy:
  • Many California cities derive from mission names (e.g., San Diego, San Francisco, Santa Clara, San Jose).
  • Monterey to San Diego missions were extensions of colonial control, with Northward expansion met by Indigenous resistance.

Case Study: Junípero Serra and Early Indigenous Resistance

• Serra founded the first mission in San Diego (1769); the Kumeyaay resisted, attacking the mission and burning it, in early resistance to missionization.

Mission Life: Labor, Culture, and Cultural Change

• Mission life consisted of a combination of religious instruction, agricultural labor, and crafts under the direction of the friars.
• Indigenous workers built and maintained mission structures; labor included brick making, farming, animal husbandry, and general construction.
• Documentation from priests and soldiers records both cooperative exchanges and coercive elements; Indigenous groups often faced coerced residence and work under various incentives.
• The missionaries’ portrayal of Indigenous people as needing Christian conversion and “civilization” is a central rationale for missionization, but the lived experience included resistance, displacement, and significant cultural disruption.
• The alliance between mission economy and colonial landholding created a system in which Indigenous people could be drawn into labor that sustained mission life while also facilitating land occupation by new colonial authorities.

Indigenous Response and Long-Term Impacts in California

• Indigenous Kumeyaay response to Spaniards was immediate and forceful, including revolts, arson, and attacks on Padres.
• Over time, the mission system contributed to drastic population declines, the erosion of traditional social structures, and significant cultural changes.
• The California mission system is a major lens for understanding broader patterns of colonization, Indigenous resistance, and the intertwining of religion, land, and empire in the early United States.
• The California case illustrates the broader pattern the author emphasizes: colonization efforts by decaying empires create conditions that foster US expansion while provoking Indigenous responses that shape policy and power dynamics.

US Westward Expansion and Major Territorial Changes (Early 1800s)

• The decline of the Spanish Empire creates a power vacuum that enables US expansion and the emergence of a hemispheric US policy framework.

Louisiana Purchase (1803)

• US acquisition of 828,000 square miles west of the Mississippi River for $15,000,000$.
• Area calculation: $A = 828{,}000 \times 640 = 529{,}920{,}000 \text{ acres}$
• Price per acre: $p_{\text{acre}} = \frac{15{,}000{,}000}{529{,}920{,}000} \, \text{USD/acre} \approx 0.0283 \,\$ / \text{acre} = 2.83 \text{ cents/acre}$
• Effect: roughly doubles the size of the United States at the time; marks the first major acquisition in a broader mid-1800s expansion.

Mexican War of Independence (Begins 1810; Formal Independence 1821)

• A wave of independence sweeps across Latin America, with most of the hemisphere achieving independence by the 1830s–1840s (Mexico in 1821, most of Latin America by 1836).

Adams–Onís Treaty (1819)

• US–Spain negotiation orchestrated by John Quincy Adams and Spain’s minister to the US.
• Principal elements:
  • Spain cedes Florida to the US.
  • Spain renounces claims to the Oregon Country.
  • The US recognizes Spanish sovereignty over Texas.
• By 1819, Eastward areas (green/pink/brown on the map) become part of the US; the western frontier remains contested and will be shaped by later conflicts and treaties.

Formulating US Hemispheric Policy (1823)

The Monroe Doctrine (1823)

• Presented through a transcript of James Monroe’s message to Congress.
• Core purpose: establish the Western Hemisphere as within US spheres of influence and curb European intervention in the Americas.
• Key questions to consider:
  • What does the document aim to accomplish in practice?
  • How does this document reflect US foreign policy, especially regarding westward expansion and manifest destiny?
  • How does the Doctrine relate to later amendments and extensions, such as the Roosevelt Corollary (1904)?
• The Monroe Doctrine becomes a foundational statement of US hemispheric policy and is later invoked to justify US actions abroad as it evolves (including later 19th–20th century interventions).
• Relationship to expansion: the doctrine is read as supporting US security and expansion interests by preventing European recolonization and influence in the newly independent states of the Americas.

Indigenous Nations and US Foreign Policy: Seminoles, Florida, and a Continental Framework

• Indigenous groups contributed to US foreign policy considerations by shaping reactions to European powers in Spanish Florida and colliding with US expansionist aims.
• Seminoles: their raids into US territory and interactions with runaways depict Indigenous resistance in an arena of competing imperial claims.
• Runaway enslaved people sought refuge in Spanish Florida; these dynamics influenced how the US interpreted territorial control and security in the hemisphere.
• The Monroe Doctrine is read in this context as a policy tool to curb recolonization attempts and to justify expanding US influence in former Spanish possessions and borderlands.
• The chapter argues that Indigenous nations actively shaped questions of sovereignty, territorial claims, and the balance of power in North America during this era.

Establishing Federal Authority over Indigenous Nations: The Marshall Trilogy

• The Marshall Trilogy refers to three landmark Supreme Court cases under Chief Justice John Marshall that establish federal supremacy in Indian affairs and outline tribal sovereignty patterns:

1. Johnson v. McIntosh (1823)

   • Doctrine of Discovery context: Indigenous people did not own land outright; only the discovering nation (the US) could legitimize land rights.
   • Implication: States cannot settle Indigenous land claims; only the federal government has standing to adjudicate such claims.

2. Cherokee Nation v. Georgia (1831)

   • Cherokee Nation sought to block Georgia laws and obtain an injunction, arguing the Cherokee Nation was a foreign nation.
   • The Court denied the injunction and characterized the Cherokee as a "domestic dependent nation" rather than a foreign nation.
   • This decision laid groundwork for the concept of tribal nations within the US framework and foreshadowed later federal authority over tribes.

3. Worcester v. Georgia (1832)

   • A missionary on Cherokee lands argued that Georgia had no authority to imprison him without a license.
   • The Court ruled in favor of Worcester, establishing that federal authority over Indian affairs supersedes state law and that tribes retain a degree of sovereignty, including internal laws and governance.

• Major implications:
  • Established that tribal sovereignty exists but is subordinate to federal authority; states have limited or no authority over tribal lands and nations.
  • Contributed to the development of the reservation system and a framework for federal Indian law.
  • Set the stage for ongoing conflicts and policy during Indian removal and other expansionist efforts.
• Sovereignty concept and debates:
  • Sovereignty is acknowledged as a unique status of tribes; the federal government has primary authority, while states retain limited powers over non-Indian matters.
  • The trilogy shows a tension between recognizing tribal sovereignty and pursuing expansionist policies (e.g., Indian removal under later administrations).
• The trilogy’s place in the broader narrative: it marks the emergence of federal power in native affairs and the legal basis for later government-Indian relations and court rulings.

Later Territorial Acquisitions (Mid-1800s)

• Oregon and Washington areas become part of territorial negotiations with Britain; the formal resolution occurs around 1846 in the context of the broader expansion narrative.
• The Gadsden Purchase (1853) finalizes the continental US border in the contiguous map (noting this as next-week content in the source).

Synthesis: Connecting Imperial Decline, Indigenous Sovereignty, and US Expansion

• The decline of the Spanish Empire opened space for US territorial growth while also creating a political vacuum that Indigenous nations helped to shape through resistance and diplomacy.
• The US used a combination of military actions, treaties, and legal doctrines to expand its land base, often leveraging the legal framework established by the Marshall Trilogy to justify federal authority over lands and peoples.
• The Monroe Doctrine then provided a strategic umbrella for hemispheric policy, linking the idea of US continental expansion with a broader hegemony in the Western Hemisphere.

Ethical and Philosophical Implications and Contemporary Debates

• The tension between religious missionization and Indigenous cultural survival.
• Debates over commemorating historical figures associated with colonization (e.g., Serra) versus acknowledging harms to Indigenous peoples.
• The ongoing question of sovereignty and self-determination for Indigenous nations within a federal system.
• Contemporary debate about Serra’s legacy: critics argue that Serra’s actions amounted to coercive colonization and cultural extermination, complicating any canonization.
• Contemporary discussions and media coverage reflect conflicting views: Serra is viewed by some as a missionary builder of California and by others as a colonial figure responsible for harm to Indigenous populations.
• The Vatican and Pope Francis have issued apologies regarding colonial-era offenses, complicating the sainthood question.
• Stanford University controversy (and similar campus debates) illustrates ongoing reassessment of historical figures tied to mission history, including renaming Serra-related buildings.
• Documentary evidence from mission records highlights both the labor contributions of Indigenous people and the coercive aspects of mission life (e.g., forced labor, forced conversion, and the suppression of traditional cultures).
• Key takeaway: the Serra controversy foregrounds the broader ethical complexities of mission history and its long-term cultural and political legacies in California.

Quick References and Takeaway Points for Exam Preparation

• Key expansions and treaties:
  • Louisiana Purchase (1803): $\sim$828,000 sq mi for $15,000,000$; roughly $0.0283/acre$ ($\sim$2.83 cents/acre).
  • Adams–Onís Treaty (1819): Florida cession; abandonment of claims to Oregon; US recognition of Spanish sovereignty over Texas.
  • Mexican War context and independence: From Hidalgo’s 1810 cry to Mexican independence in 1821; region-wide independence movements continue into the 1830s–1840s.
  • Treaty of Guadalupe Hidalgo (1848) and the Gadsden Purchase (1853) finalize much of the continental US border and acquisitions (next week’s focus).
• Foundational legal framework for federal power over Indian affairs:
  • Johnson v. McIntosh (1823): Discovery doctrine; only federal government can settle Indigenous land rights.
  • Cherokee Nation v. Georgia (1831): Domestic dependent nations; limitations on state authority over tribes.
  • Worcester v. Georgia (1832): Federal supremacy in Indian affairs; tribes retain some sovereignty.
• Monroe Doctrine (1823): US hemispheric leadership stance to curb European intervention and recolonization in the Americas; later extended by the Roosevelt Corollary.
• Indigenous role in policy formation: Indigenous conflicts and responses helped shape US strategic aims, foreign policy, and foundational constitutional interpretations of sovereignty and federal power.
• Contemporary reflections: Canonization debates of Serra and related campus renaming controversies illustrate how historical narratives continue to influence modern ethics and policy discussions.

Suggestions for Exam Practice

• Be able to explain how the decline of the Spanish Empire enabled US expansion and how Indigenous resistance intersected with this expansion.
• Compare and contrast the outcomes of the Johnson v. McIntosh, Cherokee Nation v. Georgia, and Worcester v. Georgia decisions and their implications for federal vs. state authority and tribal sovereignty.
• Explain the Monroe Doctrine’s core purpose and how it relates to westward expansion and the broader idea of Manifest Destiny.
• Outline the major land acquisitions and treaties discussed (Louisiana Purchase, Adams–Onís Treaty, Mexican independence, Treaty of Guadalupe Hidalgo, Gadsden Purchase) and their geographical/political consequences.
• Reflect on the ethical dimensions of the Spanish mission system, Serra’s legacy, and the ongoing debates about commemoration and reconciliation with Indigenous communities.
