The United Kingdom of Great Britain and Northern Ireland (commonly known as the United Kingdom, the UK or Britain) is a sovereign statelocated off the north-western coast of continental Europe. The country includes the island of Great Britain, the north-eastern part of the island of Irelandand many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea.
The United Kingdom is a unitary state governed under a constitutional monarchy and a parliamentary system, with its seat of government in the capital city of London. It is a country in its own right and consists of four countries: England, Northern Ireland, Scotland and Wales. There are threedevolved national administrations, each with varying powers, based in Belfast, Cardiff and Edinburgh, the capitals of Northern Ireland, Wales and Scotland respectively. Associated with the UK, but not constitutionally part of it, are three Crown Dependencies. The United Kingdom has fourteenoverseas territories. These are remnants of the British Empire which, at its height in 1922, encompassed almost a quarter of the world's land surface and was the largest empire in history. British influence can still be observed in the language, culture and legal systems of many of its former territories.
The UK is a developed country and has the world's sixth-largest economy by nominal GDP and seventh-largest economy by purchasing power parity. It was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great powerwith leading economic, cultural, military, scientific and political influence. It is a recognised nuclear weapons state and its military expenditure ranks third or fourth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946; it is also a member of the Commonwealth of Nations, the Council of Europe, the European Union, the G7, the G8, the G20, NATO, the OECD and the World Trade Organization.
Etymology and terminology

The name "United Kingdom of Great Britain and Northern Ireland" was introduced in 1927 by the Royal and Parliamentary Titles Act to reflect the granting of independence to the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland still within the UK. Prior to this, theActs of Union 1800, that led to the uniting the kingdoms of Great Britain and Ireland in 1801, had given the new state the name of the United Kingdom of Great Britain and Ireland. Great Britain before 1801 is occasionally referred to as the "United Kingdom of Great Britain". However, Section 1 of both of the 1707 Acts of Union declare that England and Scotland are "United into One Kingdom by the Name of Great Britain". The termunited kingdom is found in informal use during the 18th century to describe the new state but only became official with the union with Ireland in 1801.
Although the United Kingdom, as a sovereign state, is a country, England, Scotland, Wales and Northern Ireland are also referred to as countries, whether or not they are sovereign states or have devolved or other self-government. The British Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice often revealing one's political preferences." Other terms used for Northern Ireland include "region" and "province".
The United Kingdom is often referred to as Britain. British government sources frequently use the term as a short form for the United Kingdom, whilst media style guides generally allow its use but point out that the longer term Great Britain refers only to England, Scotland and Wales. However, some foreign usage, particularly in the United States, uses Great Britain as a loose synonym for the United Kingdom. Also, the United Kingdom'sOlympic team competes under the name "Great Britain" or "Team GB". GB and GBR are the standard country codes for the United Kingdom (seeISO 3166-2 and ISO 3166-1 alpha-3) and are consequently commonly used by international organisations to refer to the United Kingdom.
The adjective British is commonly used to refer to matters relating to the United Kingdom. Although the term has no definite legal connotation, it is used in legislation to refer to United Kingdom citizenship. However, British people use a number of different terms to describe their national identity. Some may identify themselves as British only, or British and English, Scottish, Welsh, or Northern Irish. Others may identify themselves as only English, Scottish, Welsh or Northern Irish and not British. In Northern Ireland, some describe themselves as only Irish.

Settlement by anatomically modern humans of what was to become the United Kingdom occurred in waves beginning by about 30,000 years ago. By the end of the region's prehistoric period, the population is thought to have belonged, in the main, to a culture termed Insular Celtic, comprising Brythonic Britain andGaelic Ireland. The Roman conquest, beginning in 43 AD, and the 400-year rule of southern Britain, was followed by an invasion by Germanic Anglo-Saxonsettlers, reducing the Brythonic area mainly to what was to become Wales. The region settled by the Anglo-Saxons became unified as the Kingdom of England in the 10th century. Meanwhile, Gaelic-speakers in north west Britain (with connections to the north-east of Ireland and traditionally supposed to have migrated from there in the 5th century) united with the Picts to create the Kingdom of Scotland in the 9th century.
The Bayeux Tapestry depicts theBattle of Hastings and the events leading to it.
In 1066, the Normans invaded England and after its conquest, seized large parts of Wales, conquered much of Irelandand settled in Scotland bringing to each country feudalism on the Northern French model and Norman-French culture. The Norman elites greatly influenced, but eventually assimilated with, each of the local cultures. Subsequent medieval English kings completed the conquest of Wales and made an ultimately unsuccessful attempt to annex Scotland. Thereafter, Scotland maintained its independence, albeit in near-constant conflict with England. The English monarchs, through inheritance of substantial territories in France and claims to the French crown, were also heavily involved in conflicts in France, most notably the Hundred Years War.
The early modern period saw religious conflict resulting from the Reformation and the introduction of Protestant state churches in each country. Wales wasfully incorporated into the Kingdom of England, and Ireland was constituted as a kingdom in personal union with the English crown. In what was to become Northern Ireland, the lands of the independent Catholic Gaelic nobility were confiscated and land given to Protestant settlers from England and Scotland. In 1603, the kingdoms of England, Scotland and Ireland were united in a personal union when James VI, King of Scots, inherited the crowns of England and Ireland and moved his court from Edinburgh to London; each country nevertheless remained a separate political entity and retained its separate political institutions. In the mid-17th century, all three kingdoms were involved in a series of connected wars (including the English Civil War) which led to the temporary overthrow of the monarchy and the establishment of the short-lived unitary republic of the Commonwealth of England, Scotland and Ireland. Although the monarchy was restored, it ensured (with the Glorious Revolution of 1688) that, unlike much of the rest of Europe, royal absolutism would not prevail. The British constitution would develop on the basis of constitutional monarchy and the parliamentary system. During this period, particularly in England, the development of naval power (and the interest in voyages of discovery) led to the acquisition and settlement of overseas colonies, particularly in North America.
