The United Kingdom is a sovereign state located off the north-western coast of continental Europe. With a total area of approximately 244,376 square kilometres (94,354 sq mi), the UK occupies the major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and many smaller surrounding islands. It is the world's 7th largest island country. The mainland areas lie between latitudes 49°N and 59°N, and longitudes 8°W to 2°E. The Royal Observatory, Greenwich, in south-east London, is the defining point of the Prime Meridian.
The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain between the Acts of Union 1707 and the Acts of Union 1800. It replaced the Peerage of England and the Peerage of Scotland, but was itself replaced by the Peerage of the United Kingdom in 1801.
The Peerage of the United Kingdom is one of the five Peerages in the United Kingdom. It comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Acts of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until 1898
The Apostolic Nunciature to Great Britain is the diplomatic office of the Holy See in Great Britain. It is headed by the Apostolic Nuncio, who has the rank of an ambassador. The parties agreed to exchange representatives at the ambassadorial level and Pope John Paul II erected the Nunciature to Great Britain on 17 January 1982. Before then, the interests of the Holy See in Great Britain had been represented by an Apostolic Delegate since 1938, though not granted diplomatic status until 1979. The decision to designate the nuncio to Great Britain rather than the United Kingdom reflected the complex and frequently antagonistic relationship between the Holy See and the British crown since they severed ties in the sixteenth century. British government sources said it had been agreed that the nuncio in London would concern himself with matters in England, Scotland and Wales, while the Apostolic Nuncio to Ireland, based in Dublin, would have within his purview the entire island of Ireland.
Local government in the United Kingdom has origins that pre-date the United Kingdom itself, as each of the four countries of the United Kingdom has its own separate system. For an overview, see Administrative geography of the United Kingdom. For details, see:
Since 1922, the United Kingdom has been made up of four countries: England, Scotland, Wales and Northern Ireland. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. Some statistical summaries, such as those for the twelve NUTS 1 regions of the UK, refer to Northern Ireland, Scotland, and Wales as "regions". With regard to Northern Ireland, Scotland and Wales particularly, the descriptive name one uses "can be controversial, with the choice often revealing one's political preferences".
A peerage is a legal system historically comprising various hereditary titles in a number of countries, and composed of assorted noble ranks.
