Introduction to Manifest Destiny
In Grade 8 US history, students learn about Manifest Destiny—the widely held belief in the 1840s that the United States was destined to expand its territory from the Atlantic to the Pacific Ocean. This idea was seen as an obvious and God-given mission to spread American democracy and ideals across the continent. Manifest Destiny drove major territorial acquisitions and shaped US policy toward Native Americans and neighboring nations. This topic is covered in History Alive! The United States Through Industrialism, Chapter 5.
Key Concepts
In the 1840s, a powerful idea swept across the United States. Many Americans came to believe it was their nation's 'manifest destiny' to expand its borders all the way to the Pacific Ocean. They felt it was an obvious and unavoidable mission to spread American ideals and ways of life across the continent.
This belief fueled a strong desire for more land and pushed the nation westward. To achieve this goal, the U.S. government used diplomacy to settle border disputes. For example, leaders from the United States and Great Britain negotiated to officially establish the border of Maine, adding new territory to the growing country.
