Great Britain

The United Kingdom (UK) was a group of countries in Europe before the Great War.

Background
The United Kingdom was formed in 1801 with the Act of Union between the Kingdoms of Great Britain and Ireland; Great Britain itself being formed in 1707 with a similar act of Union between the Kingdom of Scotland and the Kingdom of England (incorporating Wales).

From 1775 to 1783, the United Kingdom fought the newly formed United States, made up of thirteen of its North American colonies. The colonies won the war, leading to their independence from the British Empire. The United Kingdom also fought on the side of the Allied Powers during World War II, as one of the four leading countries of the alliance.

The UK also controlled many overseas territories, and at its peak led the largest empire in human history. Due to the divergence, the status of the empire, the Commonwealth of Nations, and the overseas territories is a mystery. As of 1945, such areas included Canada, parts of China, and what became Israel.

The relationship between the United Kingdom and the Irish state 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 as this was shortly after or before the divergence. The capital city of Wales is also unknown; while it is Cardiff in our world, Cardiff did not become the Welsh capital until 1955.

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

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, hinting at some of the possible conditions in post-War Britain. The ancestors of Colin Moriarty also left Ireland for the Capital Wasteland shortly after the Great War for unknown reasons.
