U.S. state

A U.S. state is any one of the 50 states which have membership of the federation known as the United States of America (USA or US). The individual state governments and the U.S. 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 each individual state.

At the time of the Declaration of Independence from Great Britain, the 13 colonies became 13 independently sovereign states. After the failure of the union under the Articles of Confederation, the 13 states joined the modern union via ratification of the Constitution, beginning in 1789.

The United States Congress has the power to admit new 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."
