Question

Discuss the westward territorial expansion of usa in the 1940s

Answer 1

By 1820, the United States already extended well beyond its original boundaries. Through the Louisiana Purchase of 1803 and treaties with Spain and Britain, the nation's borders moved west to the Rocky Mountains, north to the 49th parallel, and south to Florida and the Gulf of Mexico. These boundaries remained essentially intact until the 1840s, when the United States acquired massive territories in the Southwest and on the Pacific Coast.

A complex mix of political, social, and economic factors fueled American expansionist sentiment in the 1840s. Many Americans subscribed to the concept of "Manifest Destiny," the belief that Providence preordained the United States to occupy as much land on the continent as possible. Some saw lucrative economic opportunities in the vast stretches of arable land and superb Pacific Coast ports. Others dreamed of the romance of settling uncharted terrain, or thought the United States should expand rapidly across the continent before foreign nations could do so. These expansionist yearnings fueled American settlement in Texas and Oregon, the acquisition of which became a principal object of American foreign policy by 1845.

Answer 2

In 1803, President Thomas Jefferson purchased the territory of Louisiana from the French government for $15 million. The Louisiana Purchase stretched from the Mississippi River to the Rocky Mountains and from Canada to New Orleans, and it doubled the size of the United States.
