U.S. state
A U.S. State is any one of the fifty states which have membership of the federation known as the United States of America (USA or US). The individual states and the US federal government share sovereignty. Under the United States Constitution, the federal government can legislate only on matters explicitly delegated to it by the Constitution, with the remaining governmental powers belonging to the states.

In addition to the states, several other areas belong to or have associations with the United States:
- AS American Samoa
- DC District of Columbia, which is the seat of the Federal government
- GU Guam
- MP Northern Mariana Islands, Commonwealth
- PR Puerto Rico, Commonwealth
- VI the U.S. Virgin Islands
- Midway Atoll
- Guantanamo Bay (the US has "complete jurisdiction and control" under a lease from Cuba, which retains ultimate sovereignty)
Unlike states, the authority to rule dependent areas comes not from the people of those areas but from the Federal government, however in most cases Congress has granted a large amount of self-rule.
At the time of the Declaration of Independence from Great Britain, 13 states existed. The United States Congress has the right/power to admit states to the Union.
The Constitution is silent on the issue of the secession of a state from the United States. The Civil War was fought to prevent states from leaving the Union. Some people claim that it is still not established whether any state can secede legally. Prior to the adoption of the Constitution, the Articles of Confederation stated that "the union shall be perpetual."
States may be grouped in regions; there are endless variations and possible groupings, as most states are not defined by obvious geographic or cultural borders. For further discussion of regions of the U.S., see the list of regions of the United States.
