United States history II: after 1877

Investigate the relationship between economic transformation, public power and citizenship after Reconstruction.

Introductory survey and inquiry sequence. Independent primary-source reading, scholarly bibliography and human-reviewed research are required for the proposed project. This site does not award college credit. The I/II boundary is 1877: I ends with Reconstruction; II begins after it. Boundary context may be revisited without duplicating the survey requirement. Course update, 25 October 2026: six shared investigations and new allotment, Chinese-exclusion, Pullman labor, senatorial reform and Social Security investigations now join the later U.S. history sequence. They count in this course’s current lesson total, so its completion fraction can change. Existing lesson completions, drafts, attempts and project submissions are retained; this update does not revoke them. The college History II path expands from four to fifteen investigations. This is still developing survey coverage: broader industrial labor history, western expansion and Indigenous sovereignty, broader immigration history, Progressive reform, the New Deal, world wars, postwar social change and recent history require further dedicated depth.

Preparation and direct entry
  • Use source-evaluation refreshers as needed; no prior sequence completion is required.
  • Later U.S. history sequence: use each broad period investigation for context, then the linked focused cases for evidence. Some cases compare dates across periods; their placement is thematic, not a claim that all events occurred in one year.
  • Immigration and exclusion: map the 1882 act by provision. Separate entry, return documentation and naturalization, then distinguish what the statute establishes from what requires affected people’s records.
  • Allotment and sovereignty: classify records by administrative stage, compare the original statutory exception with later Cherokee history, and distinguish land tenure from political authority.
  • Industrial labor: map the Pullman company’s employer/landlord roles, the union network and distinct government responses. Keep the fictional budget calculation separate from observed historical earnings.
  • Migration and industry: build a population-change calculation and a three-source exhibit plan. Distinguish migration from births/deaths and connect employment, housing and cultural expression without assigning every migrant the same experience.
  • Progressive reform: analyze Berryman’s deadlock cartoon, compare senatorial selection rules and distinguish advocacy, ratification, elections and access to voting.
  • New Deal institutions: compare assistance and insurance, test the 1937 payroll cap and exclusions, and distinguish enactment, amendment, adjudication and payment.
  • War and rights: compare the 1919 and 1969 speech cases. Keep wartime prosecution, school expression and later incitement doctrine separate; an unfamiliar case tests which analogy actually fits.
  • Cold War and citizenship: connect Truman’s requested assistance, the Cuban crisis commitments, court holdings and movement organizing. Keep proposal, ruling, implementation and lived access in separate evidence columns; do not infer results from an announcement.
  • Carry one revised claim from these cases into your existing course project. Record source IDs, event dates, source dates, a competing explanation and missing evidence. Shared investigations retain prior attempts; revisiting through this course is practice, not a new unseen assessment.

    Equal protection can arise in education and representation, but the legal questions differ.

Cumulative projectSaved workspace · human review remains separate
CUMULATIVE PROJECT

Independent U.S. history II inquiry

Investigate the relationship between economic transformation, public power and citizenship after Reconstruction. Select a bounded question, at least three primary sources and two scholarly interpretations, then defend the source selection.

Evidence and review criteria

  • The question names a place, period and population, and the chronology is accurate.
  • Claims use identified evidence; source creator, purpose, context and limits are explained.
  • The explanation tests an alternative and distinguishes association, causation and value judgment.
  • Different experiences are represented without fabricating missing testimony or treating a group as uniform.
  • The artifact includes citations, accessible text descriptions and a visible revision after new evidence.
  • The argument distinguishes formal legal status from practical enforcement.

Use your lesson captures and citations. This saved workspace supports a reviewer; it does not automatically grade your writing or certify proficiency.

Review examples and quality criteria

These are authored teaching examples for practicing review, not calibrated scoring standards. Apply your course’s specific rubric above. Different conclusions can be defensible when evidence supports them; factual and numerical errors still require correction.

Claim needing revision

The author lived then, so the account proves what everyone thought.

More defensible reasoning

The account supports a claim about this author’s stated position in this setting. Its audience and purpose may shape what is emphasized. Compare a contemporaneous source from a different position before extending the claim to a wider population.

Why the revision helps

The revision preserves the primary source’s value while restricting the population claim. A stronger completed response would name the actual author, date, audience and contrasting passage.

Assess the artifact, with assistance recorded separately

Question and contextA broad topic or undefined population.A focused question, time/place and relevant definitions.A justified scope with context that changes the interpretation.

Transfer and revisionRepeats the worked answer despite changed facts.Adapts the reasoning to the unfamiliar case.Explains why the change matters and what evidence would reverse the conclusion.

Use “missing” when no relevant evidence is supplied. Do not average these descriptions into an automatic pass score. Record whether the learner followed an example, used guidance or worked independently, and review quality separately.

  1. Locate one specific claim and its supporting source or calculation.
  2. Check the context, units and intermediate reasoning.
  3. Identify one plausible alternative and the evidence that distinguishes it.
  4. Ask for a revision or an unfamiliar application; explain the reason for the request.

NEW APPLICATION · VERSION 1

Migration, wages and competing accounts

Use this packet for a fresh written application. All records below are original fictional teaching materials. They test reasoning under stated conditions and do not establish actual historical or population facts. Your original course-project draft remains separate.

Record wages

Citation ID: social:independent:us-later:v1-wages

Fictional city study, 1910–1920: average daily manufacturing pay rises from 2 to 3 currency units; the local living-cost index rises from 100 to 140. Hours and employment composition are not supplied.

Record voices

Citation ID: social:independent:us-later:v1-voices

A recruitment leaflet promises higher pay. One migrant's letter reports better earnings but costly housing. Both are invented teaching accounts representing different purposes, not quotations from historical people.

Record revised-count

Citation ID: social:independent:us-later:v1-revised-count

A later audit finds the 1920 pay sample excludes laid-off workers and domestic workers. City employment totals are unavailable.

This case is shared across paths that use it. Revisiting it in another course retains drafts and known review-note exposure; it is not a new unseen assessment.
