Great Britain

The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland, but more commonly known as the UK or Britain was a country located in Europe before the Great War.

Background
The United Kingdom was formed in 1801 with the Act of Union between the Kingdom of Great Britain and 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 part becoming and independent Irish country.

From 1775 to 1783, the Kingdom of Great Britain fought the newly formed United States, made up of thirteen of its North American colonies. The American rebels won the war, leading to their independence and establishment as an independent, sovereign country. 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 are unknown, since Ireland did not officially declare itself a republic or leave the Commonwealth of Nations until 1949. It is likely however, 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; while it is Cardiff in the real world, Cardiff 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 ancestors of Colin Moriarty also left Ireland for the Capital Wasteland shortly after the Great War for unknown reasons, also possibly hinting at some of the possible conditions in the post-War Ireland.

The United Kingdom was a member of the European Commonwealth until its dissolution in 2060. The United Kingdom quarelled with other former members of the Commonwealth over the last remaining quantities of oil on Earth, sparking a bloody conflict known as the European Civil War.
