Westward Expansion:
Manifest Destiny and the Growth of the United States
In the early 19th century, the United States experienced a period of significant territorial expansion known as Westward Expansion. This expansion was fueled by the concept of Manifest Destiny, the belief that it was the destiny of Americans to expand their nation from coast to coast. This unit explores the concept of Manifest Destiny and the westward migration that shaped the growth of the United States.
The United States began its westward expansion with the acquisition of the Louisiana Territory, the annexation of Texas, and the addition of the Mexican Cession and Oregon Territory. The initial phase of westward expansion involved the migration of settlers from the eastern states into the Ohio River valley and the territory northwest of the Ohio River.
After these initial migrations, settlers continued to move westward, crossing the Rocky Mountains and venturing into the newly acquired territories. The discovery of gold in California attracted a large number of settlers, leading to the establishment of settlements along the west coast. Meanwhile, the settlement of the Great Plains region began during the Civil War and extended into the early 20th century.
The westward expansion brought about significant political, economic, and geographic changes in the United States. As Americans pursued the concept of Manifest Destiny, they sought new opportunities in the newly acquired territories. This expansion also led to the development of a unique American cultural trait known as "rugged individualism," which emphasized self-reliance and independence.
Studying westward expansion is crucial for understanding the geographic scope of the United States and for comprehending the idea of "rugged individualism" that remains a significant aspect of American culture. Through this unit, students will explore the historical context, motivations, and consequences of westward expansion, gaining a deeper understanding of how it shaped the nation.
