Westward Expansion

Westward Expansion refers to the period in United States history when the country grew and expanded westward across the North American continent. This expansion was driven by a variety of factors, including economic opportunities, the desire for land, and the belief in the idea of Manifest Destiny, which held that it was the nation's destiny to expand from the Atlantic to the Pacific.

Key Events and Concepts

1. Lewis and Clark Expedition (1804-1806): This was the first official exploration of the American West, commissioned by President Thomas Jefferson. Meriwether Lewis and William Clark led a group to explore and map the newly acquired Louisiana Territory.
2. Manifest Destiny: This was the belief that it was the United States' destiny to expand across the continent. This idea fueled the acquisition of new territories and the displacement of Native American tribes.
3. Oregon Trail: The Oregon Trail was a 2,170-mile historic east-west large-wheeled wagon route that connected the Missouri River to valleys in Oregon. It was used by immigrants during the 19th century to settle in the Oregon Territory.
4. Mexican-American War (1846-1848): The war between the United States and Mexico resulted in the acquisition of vast territories in the American Southwest, including California, Arizona, New Mexico, and parts of Colorado, Nevada, and Utah.
5. Gold Rushes: The California Gold Rush of 1848–1855 and subsequent gold rushes in Colorado, Nevada, and South Dakota prompted a mass migration of people seeking wealth and opportunities in the West.
6. Homestead Act (1862): This act provided 160 acres of public land to settlers in exchange for improving the land by building a dwelling and cultivating crops. It encouraged westward migration and the development of agriculture in the West.
7. Transcontinental Railroad: The completion of the First Transcontinental Railroad in 1869 connected the eastern and western United States, making it easier for people and goods to travel and settle in the West.
8. Treaty of Guadalupe Hidalgo (1848): This treaty ended the Mexican-American War and resulted in Mexico ceding a vast amount of territory to the United States, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming.
