This map illustrates the expansion of the United States from the [Treaty of Paris](https://www.worldhistory.org/Treaty_of_Paris_of_1783/) (1783) to the mid-19th century, a period in which the young republic transformed from thirteen coastal states into a nation spanning the breadth of North America. In just a few decades, the country more than quadrupled its territory, pushing its western frontier from the Mississippi River to the Pacific Ocean.

The process began with the Treaty of [Paris](https://www.worldhistory.org/disambiguation/paris/) (September 3, 1783), which ended the [American Revolutionary War](https://www.worldhistory.org/American_Revolutionary_War/) and secured recognition of U.S. independence along with land stretching to the Mississippi. A major turning point came with the [Louisiana Purchase](https://www.worldhistory.org/Louisiana_Purchase/) (1803), when President [Thomas Jefferson](https://www.worldhistory.org/Thomas_Jefferson/) (president: 1801–1809) acquired 828,000 square miles (about 2.1 million km²) from Napoleonic France, doubling the country’s size. Further expansion followed: Florida was ceded by Spain in 1819, the annexation of Texas occurred in 1845, the Oregon Treaty with [Britain](https://www.worldhistory.org/disambiguation/Britain/) in 1846 secured the Pacific Northwest, and the [Mexican-American War](https://www.worldhistory.org/Mexican-American_War/) (1846–1848) added vast southwestern territories through the Treaty of Guadalupe Hidalgo. By mid-century, the United States had extended from the Atlantic seaboard to the Pacific coast, establishing itself as a transcontinental republic.
