AP U.S. History / Period 6: 1865–1898
Lesson
The West and the politics of incorporation
The federal government folded the West into a national market.
Learning goals
- Explain western expansion as policy, not empty land filling up.
- Connect incorporation of the West to Native dispossession.
Explanation
Homestead laws, railroad land grants, mining, and commercial ranching pulled the West into national markets. The same state that advertised opportunity also waged wars, broke treaties, and confined Native nations to reservations. 'The frontier' was not empty; it was a contested political space.
Populists and other agrarian critics later argued that railroads, banks, and gold-standard policy squeezed farmers. Whether you agree with their remedies, their complaints show that incorporation created losers as well as boomtowns. Period 6 is national because the West, the factory, and Congress were tied together.
Key terms
- reservation. Land designated by the federal government for a Native nation, usually after dispossession of a larger homeland.
- Populism. A late-century agrarian political movement that criticized banks, railroads, and the gold standard.
Common mistakes
- Describing the West as vacant land waiting for settlers.
- Separating 'Indian wars' from the economic project of railroads and markets.
