Expansion into the American West, 1839-60
The period from 1839 to 1860 saw a dramatic shift in American attitudes towards the West, transforming it from a perceived desert to a land of opportunity. This expansion had significant impacts on Native American tribes and the nation's economic and political landscape.
Definition: Nomadic lifestyle - a way of life in which a group of people moves from place to place rather than settling in one location.
The Plains Indians, particularly the Sioux and Cheyenne, adapted their way of life to the challenging environment of the Great Plains:
- The introduction of horses by the Spanish enabled tribes to adopt a nomadic lifestyle.
- Buffalo hunting became central to their culture and survival.
- Tribal leadership and social structures were organized around this nomadic way of life.
Highlight: The Sioux dominated the Plains from the 1820s to 1860s, displacing other tribes like the Crow and Arapaho.
The expansion into the West was driven by several factors:
- Changing perceptions of the land's value and habitability
- Economic opportunities, particularly in fur trading
- Territorial acquisitions from European powers and Mexico
This westward movement set the stage for future conflicts between white settlers and Native American tribes, as well as debates over the expansion of slavery into new territories.
Vocabulary: Nomadically - relating to a way of life that involves moving from place to place rather than living in one location permanently.
The chapter emphasizes the rapid transformation of the American West from a sparsely populated region to an area of intense interest and settlement. This shift would have profound implications for the nation's future development and its relationships with indigenous peoples.
