Declarations of independence
Sometimes, a state wishing to achieve independence from a dominating power will issue a declaration of independence; the earliest surviving example is Scotland's Declaration of Arbroath in 1320, with the most recent example being Azawad's declaration of independence in 2012. Declaring independence and attaining it however, are quite different. A well-known successful example is the U.S. Declaration of Independence issued in 1776. The dates of established independence (or, less commonly, the commencement of revolution), are typically celebrated as a national holiday known as an independence day.
