⭐ Core Definition: American territorial expansion

The United States of America was formed after thirteen British colonies in North America declared independence from the British Empire on July 4, 1776. In the Lee Resolution, passed by the Second Continental Congress two days prior, the colonies resolved that they were free and independent states. The union was formalized in the Articles of Confederation, which came into force on March 1, 1781, after being ratified by all 13 states. Their independence was recognized by Great Britain in the Treaty of Paris of 1783, which concluded the American Revolutionary War. This effectively doubled the size of the colonies, now able to stretch west past the Proclamation Line to the Mississippi River. This land was organized into territories and then states, though there remained some conflict with the sea-to-sea grants claimed by some of the original colonies. In time, these grants were ceded to the federal government.

The first great expansion of the country came with the Louisiana Purchase of 1803, which doubled the country's territory, although the southeastern border with Spanish Florida was the subject of much dispute until it and Spanish claims to the Oregon Country were ceded to the US in 1821. The Oregon Country gave the United States access to the Pacific Ocean, though it was shared for a time with the United Kingdom. The annexation of the Republic of Texas in 1845 led directly to the Mexican–American War, after which the victorious United States obtained the northern half of Mexico's territory, including what was quickly made the state of California.

American territorial expansion in the context of US imperialism


American imperialism or US imperialism is the exercise of power or control by the US outside its borders. It operates through military conquest; military protection; gunboat diplomacy; unequal treaties; support for preferred factions; regime change; economic or diplomatic support; economic interference via private companies, or influence on local culture and media, potentially followed by intervention when American interests are threatened.

American imperialism and expansionism took the form of "New Imperialism" beginning in the late 19th century, although authors such as Daniel Immerwahr consider earlier American territorial expansion across North America at the expense of Native Americans to fit the definition. While the US has never officially identified itself and its territorial possessions as an empire, some commentators have done so, including Max Boot, Arthur M. Schlesinger Jr., and Niall Ferguson. Other commentators have accused the US of practicing neocolonialism—dominating territory via indirect means—which leverages economic power rather than military force.

American territorial expansion in the context of American hegemony


American imperialism is the exercise of power or control by the US outside its borders. The US expanded its territory initially via conquest, later shifting to controlling/influencing other countries without conquest, using techniques such as alliances; aid; gunboat diplomacy; treaties; trade; support for preferred political factions; regime change; economic influence via private companies, exports of culture and media. Military interventions have been used to support allies, expel invaders, overthrow governments, and support US economic interests.
