What this topic is asking
Topic 3.12 asks you to explain the movement of peoples in the new nation, above all the westward migration across the Appalachians after independence, and its consequences: rising conflict with American Indian nations and the government's attempts to organize the western territories. The thread is land, who would settle it, who already lived there, and how it would be governed.
The pull westward
Conflict with American Indian nations
The land settlers wanted was not empty. It was home to powerful American Indian nations, and migration produced repeated, violent conflict:
- Settlers encroached on Native land, often ignoring treaties and the earlier Proclamation line.
- The federal government pursued displacement through treaties (often coerced) and military force.
- Native nations resisted and adapted, sometimes forming confederacies and defeating American forces before later setbacks.
The exam rewards presenting Native peoples as active, resisting and negotiating, not merely as victims of an inevitable advance.
Organizing the West
The government answered the chaos of settlement with policy:
This organization also embedded a fuse: by barring slavery north of the Ohio while leaving it open elsewhere, the ordinances foreshadowed the bitter question of slavery's expansion into new territories.
Worked example: arguing migration drove Native conflict
Try this
Q1. Name the 1787 ordinance that organized the territory north of the Ohio River for statehood. [Recall]
- Cue. The Northwest Ordinance, which created a path to new statehood and barred slavery in the Northwest.
Q2. Explain why westward migration after 1783 produced conflict with American Indian nations. [Short explanation]
- Cue. The land settlers sought across the Appalachians was already home to Native nations, so as settlers encroached and the government pursued displacement through coerced treaties and force, Native peoples resisted, producing recurring violent conflict on the frontier.

A Long Essay Question (LEQ), scored on the 6-point rubric.
Thesis (1): "Westward migration was the driving force in relations with American Indians, because settler pressure on Native land produced recurring conflict that the new government could neither prevent nor justly resolve."
Contextualization (1): the territorial gains of the Treaty of Paris of 1783 that opened the trans-Appalachian West.
Evidence (2): settler migration into the Ohio valley; conflict and Native resistance; the Northwest Ordinance's organization of the land.
Analysis (2): explain HOW migration drove conflict and displacement, then add complexity by noting Native resistance and adaptation rather than passive loss.
