Organized incorporated territory


Organized incorporated territories are territories of the United States that are both incorporated (part of the United States proper) and organized (having an organized government authorized by an Organic Act passed by the U.S. Congress, usually consisting of a territorial legislature, territorial governor, and a basic judicial system). There have been no such territories since Alaska and Hawaii were admitted as states in 1959.

Through most of U.S. history, regions that were admitted as U.S. states were, prior to admission, territories or parts of territories of this kind. As the United States grew, the most populous parts of the organized territory would achieve statehood. The remainder frequently kept at least some of the governing structure of the old legal entity (territory) and would be renamed to avoid confusion.

Some territories existed only a short time before becoming states, while others remained territories for decades. The shortest-lived was Alabama Territory at two years, while New Mexico Territory and Hawaii Territory both lasted more than 50 years.

Of the current 50 US states, 31 were at one time or another part of a U.S. territory (see list below). The exceptions include: the original Thirteen Colonies; Kentucky and West Virginia (both split off from Virginia); Maine (split off from Massachusetts); California (created as a state out of the unorganized territory of the Mexican Cession); and Vermont and Texas (both previously self-declared republics).
