USA HISTORY

Detailed explanation-1: -U.S. President Thomas Jefferson’s Louisiana Purchase in 1803 had doubled the size of the country, sparking people’s desire to move west. Spreading settlements along the country’s borders caused friction with others. The intervention of the U.S. government often resulted in the annexation of more territory.

Detailed explanation-2: -The acquisition of the Louisiana Territory encouraged the settlement and acquisition of Texas from Mexico. The acquisition of Texas led to demands for the acquisition of California from Mexico as well. These expansions both spurred and fulfilled the idea of Manifest Destiny.

Detailed explanation-3: -The purchase doubled the size of the United States, greatly strengthened the country materially and strategically, provided a powerful impetus to westward expansion, and confirmed the doctrine of implied powers of the federal Constitution.

Detailed explanation-4: -The land bought stretched from today’s Louisiana to north most of today’s Minnesota. It also went westward to half of what is today’s Wyoming, Colorado, and Montana. Without this major purchase being made, westward expansion would not have occurred and Manifest Destiny would not have been achieved.

Detailed explanation-5: -One was to “secure us the Mississippi and its mouths, and a portion of the Gulf shore”("St. Thomas") and the other was the belief that Americans were destined by God to reign over the entire continent. The ideology of Manifest Destiny influenced the United States want to expand across the continent.
