There are a number of dependent territories of the United Kingdom throughout the world. As dependencies, they are not part of the UK proper, but nor are they independent states. Each has its own distinct legally defined relationship with the UK, with the monarchy of the United Kingdom as head of state. The remaining Crown colonies of the British Empire were renamed "British Dependent Territories" from 1 January 1983 under the British Nationality Act 1981, and were renamed again on 26 February 2002 to "British Overseas Territories" by the British Overseas Territories Act 2002. These territories fall into two broad categories: British Overseas Territories and Crown Dependencies.
