The United States of America in 1800

In the year 1800, the United States was administratively divided into a few key entities. Here are the main administrative divisions during that time:

States: The United States had a total of 16 states: Connecticut, Delaware, Georgia, Kentucky, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, and Virginia.

Territories: There were three major  territories under the control of the United States government in 1800. The Northwest Territory, which encompassed areas that would later become the states of Ohio, Indiana, Illinois, Michigan, Wisconsin, and parts of Minnesota, had been divided in 1800 into two territorial governments: the eastern division, a smaller Territory North-West of the River Ohio, would become the state of Ohio in 1803 and the western division became the Indiana Territory. In the South, there was the Mississippi Territory (including parts of present-day Mississippi and Alabama).

District of Columbia: The District of Columbia was officially recognized as the federal district in 1801 and established as seat of the national government. It was not part of any state and was directly under the control of the federal government. The District of Columbia included the city of Washington, D.C., which became the capital of the United States.

These administrative divisions were subject to change and expansion as the United States acquired new territories and admitted new states. Over time, the country continued to grow and reorganize its administrative divisions to accommodate its expanding population and territories.
