Write a short summary on how James Polk was apart of Westwards Expansion.

James K. Polk played a significant role in Westward Expansion during his presidency from 1845 to 1849. Polk, a believer in Manifest Destiny, sought to acquire new territories for the United States and expand the country's borders. His administration achieved several key achievements in this regard.

Firstly, Polk orchestrated the negotiation and signing of the Oregon Treaty with Britain in 1846. This treaty secured the United States' claim to the Oregon Territory, extending the nation's boundaries to the Pacific Northwest. This expansion opened up vast new opportunities for settlement and trade in the western region.

Additionally, Polk played a crucial role in the Mexican-American War (1846-1848), during which the United States aimed to secure more territories in the Southwest. Polk ordered the American army to occupy disputed territories between the Rio Grande and Nueces Rivers, leading to a conflict with Mexico. Through military victories and diplomatic negotiations, the United States gained several territories, including California and New Mexico, as a result of the Treaty of Guadalupe Hidalgo in 1848.

Furthermore, Polk supported and encouraged the migration of Americans to the western frontier. He implemented policies like the Homestead Act, which granted settlers free land in the West, and oversaw the construction of infrastructure projects like the Transcontinental Railroad. These initiatives paved the way for the settlement and economic development of the western territories.

Overall, James K. Polk's presidency was marked by vigorous efforts to expand the United States westwards. Through negotiations, military actions, and policies promoting westward migration, Polk significantly contributed to the expansion of the country's territory and played a key role in shaping the United States' westward growth.
