Right to keep and bear arms in the United States

In the United States, the right to keep and bear arms is a fundamental right protected by the Second Amendment to the United States Constitution, part of the Bill of Rights, and by the constitutions of most U.S. states. The Second Amendment declares:

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

Stemming from English common law tradition, the concept of a right to keep and bear arms was recognized prior to the creation of a written national constitution.
