The Early Republic and Westward Expansion
Aligned to C3.D2.His — C3 Framework for Social Studies State Standards.
What this lesson teaches
After winning independence, the young United States grew fast — setting up its government, doubling in size with the Louisiana Purchase, and pushing westward. Expansion created opportunity for settlers but forced Indigenous peoples off their land and deepened conflict over slavery.
Worked example
The Louisiana Purchase (1803) bought a huge territory from France and doubled the country's size. Settlers moved west, but treaties with Native nations were broken repeatedly, leading to forced removals like the Trail of Tears.
Practice questions
- What did the Louisiana Purchase do for the United States?
- Name one effect of westward expansion on Native nations.
- Why did expansion increase tensions over slavery?

La República Temprana y la Expansión hacia el Oeste
Después de ganar la independencia, los Estados Unidos crecieron rápidamente: establecieron su gobierno, duplicaron su tamaño con la Compra de Luisiana y avanzaron hacia el oeste. La expansión creó oportunidades para los colonos, pero obligó a los pueblos indígenas a abandonar sus tierras y profundizó el conflicto en torno a la esclavitud.
Ejemplo: La Compra de Luisiana (1803) adquirió un enorme territorio de Francia y duplicó el tamaño del país. Los colonos se trasladaron al oeste, pero los tratados con las naciones nativas fueron incumplidos repetidamente, lo que provocó desplazamientos forzados como el Sendero de las Lágrimas.
