The Bill of Rights, or the first ten amendments to the U.S. Constitution, were ratified on December 15, 1791, 222 years ago today. However, it wasn’t until 1941, on the 150th anniversary of the ratification of the Bill of Rights, that Bill of Rights Day was recognized as a national holiday.

This Bill of Rights Day, the Cato Institute invites you to share what the Bill of Rights means to you.
