Manifest Destiny's Contribution Towards Westward Expansion Of The United States

Introduction When the United States began as the 13 colonies, the idea of Manifest Destiny began to spread rapidly throughout the country. The term Manifest Destiny refers to the nineteenth century idea that God had chosen the American people to expand westward across North America towards the Pacific Ocean. This idea was heavily favored by Americans and was desperate to be achieved. Many events that occurred throughout the nineteenth century in the United States helped shape Western America and contributed towards westward expansion. Some of these events include the debate over the institution of American slavery, the US-Mexico War, and the US Civil War.

When the United States and Mexico met to discuss an agreement, the United States came with more requests. This included the purchase of California, the purchase of New Mexico, and the payment of damages to US nationals for losses incurred in Mexican revolutions. When Mexica refused the requests, the United States began to push south towards the Rio Grande. Through a series of battles within the span of two years, the United States came out successful.
