Great Britain

The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland or simply Britain, was a country located in Europe before the Great War.

Background
On October 14, 1066, the Battle of Hastings was fought in England as part of the Norman conquest, led by William the Conqueror. In 1215, the Magna Carta was signed by King John of England and English barons, greatly limiting his authority as king and placing more power into the hands of the feudal government. On March 25, 1634 Lord Baltimore of the Irish House of Lords dispatched the first colonists to Maryland. They would land near the area that would later become Point Lookout aboard two ships, the Ark and the Dove.

On April 19, 1775, the Battles of Lexington and Concord occured, starting the American Revolutionary War, fought between the Kingdom of Great Britain and the newly formed United States, made up of thirteen of its North American colonies. On July 4, 1776, the United States Declaration of Independence was adopted by the Second Continental Congress, explaining to the British why they were at war with them and announcing the United States' intent to independently govern itself. The war would continue until 1783 with the Treaty of Paris, which confirmed American independence.

The United Kingdom was formed in 1801 with the Act of Union between the Kingdom of Great Britain and the Kingdom of Ireland; the Kingdom of Great Britain itself being formed in 1707 with a similar act of Union between the Kingdom of England and the Kingdom of Scotland (Wales at the time being considered part of England). The United Kingdom of Great Britain and Northern Ireland, the latest incarnation of a British state, was formed after the Irish War of Independence, resulting in a part of Ireland referred to as Northern Ireland remaining with the United Kingdom, and the other becoming an independent Irish state known as the Republic of Ireland.

The United Kingdom also fought on the side of the Allies during World War II, as one of the four leading countries of the alliance.

The United Kingdom controlled many overseas territories, and at its peak led the largest empire in human history. Due to the divergence, the status of the British Empire and the Commonwealth of Nations is unknown. As of 1945, such areas included Canada, parts of the Europe and would become the nation of Israel.

The relationship between the United Kingdom and Ireland in the Fallout universe is unclear, since Ireland did not officially declare itself a republic or leave the Commonwealth of Nations until 1949. It is likely that these events still transpired, considering that the national flag of Ireland is found multiple times in the Commonwealth. This flag, while created in 1830, did not enter common usage until Ireland became a republic in 1949 and the flag was adopted as the national flag of Ireland. The capital city of Wales is also unknown, as Cardiff serves as the capital in the real world, the city did not become the Welsh capital until 1955.

Dialogue suggests that the country was ruled by a queen before the outbreak of the Great War.

No details are known about the state of the British Isles after the Great War. However, in the 23rd century, Allistair Tenpenny left the country for the Capital Wasteland in the United States to seek wealth and fortune, possibly hinting at some of the possible conditions in the post-War United Kingdom.

The United Kingdom was a member of the European Commonwealth until its dissolution in 2060. The various members of the now-defunct Commonwealth began to quarrel with one another over the last remaining oil reserves on Earth, eventually sparking a bloody conflict known as the European Civil War.

Ireland
There are several characters of Irish descent from the island of Ireland in the Fallout series. It is never explicitly stated whether Ireland is part of the United Kingdom in the games' timeline, or even if Northern Ireland exists, but in the Commonwealth, there is an abundance of Irish national flags, which did not become popularly used until 1922 after 26 counties of Ireland separated from the United Kingdom to form the Republic of Ireland, indicating it was a separate nation. However, it is possible that the 6 counties of Northern Ireland, which form part of the four countries in the United Kingdom in the real world, may be the place of origin for characters with vaguer ties (such as last names and generic Irish accents).

Other

 * The American Revolutionary War, and several key British figures who were active during that timeframe such as King George III, and Thomas Gage, are referenced in Fallout 3 and Fallout 4.
 * In Fallout 4, a Mr. Handy called Whitechapel Charlie, has a small Union Flag on his chassis. This suggests that, unlike the United States, the United Kingdom had such a flag prior to the Great War.
 * In the Fallout 76 add-on Wild Appalachia, the United Kingdom is listed as the correct answer to the question, "Which country was the first to build a major railway system?" in an exam at the Pioneer Scout camp.
 * Some examples of British military equipment exist in the Fallout universe. Weapons such as the Sten gun and the light support weapon were developed by Royal Small Arms Factory.
 * The light support weapon (LSW) being featured in the Fallout universe may give some information about the United Kingdom, as the weapon was developed and issued in the mid-1980s and is past the point of Divergence.
 * A British Boudicca-78/S motorcycle was to be the first vehicle found for use in Van Buren.
