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


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.[1]

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.[2]

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 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.

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, but in the Commonwealth, there is an abundance of Irish republican flags, which did not become popularly used until 1922 after Ireland broke away from the United Kingdom. Therefore, it is most likely a republic did form in this timeline.

  • Patrick the Celt from Fallout is descended from Americanized Celts and keeps his heritage alive by collects clothing, food, stories, songs and knowledge of Celtic history. He knows the Irish song Na Gheala Mbeadh (which is very poor Irish for "The Light Would," possibly a mistranslation of "Mo Ghile Mear," or "My Gallant Darling").

Behind the scenesEdit

  • "Allistair Tenpenny came to the Capital Wasteland from Great Britain to seek his fortune, so that alone tells you that the U.K. was also hit in the war. And if he came to U.S. to succeed, that says a lot about how screwed up Europe must be. So we just allude, a little bit, to the state of the rest of the world. We like to leave a lot to the players' imaginations, and somebody like Tenpenny serves as a catalyst for those thoughts." – Emil Pagliarulo[12]
  • James, the Lone Wanderer's father, speaks with an Irish accent because The voice actor who portrays him, Irish actor Liam Neeson, used his natural speaking voice to portray him.
