European Commonwealth

Fallout intro information
The European Commonwealth was the Fallout equivalent of the integrated into one state real-world European Union, although it is not known which European states were its members (the only confirmed one is the United Kingdom). In 2052 Europe was dependent on oil exports from the Middle East, and responded to rising oil prices with a military action (starting the Resource Wars), which suggests that unlike today's EU, the EC was also a military pact. Some time after the war ended, as the Middle Eastern oil fields went dry in 2060, European Commonwealth dissolved into quarreling nation states fighting for the remaining resources.

Founding treaties
The European Commonwealth probably was created on the basis of european economic communities:
 * the European Coal and Steel Community, established by Treaty of Rome of 1951, declared to be "a first step in the federation of Europe".The founding members of the Community were Belgium, France, Italy, Luxembourg, Netherlands and West Germany.
 * the European Economic Community and the European Atomic Energy Community, established by Treaty of Paris of 1957.

In real world the United Kingdom joined in 1973 (together with Denmark and Ireland).

European military organization, that could be integrated into the European commonwealth could be Western European Union (WEU), established on the basis of the Treaty of Brussels of 1948. On 15 May 1995, the Council of Ministers of the WEU met in Lisbon. Declaration of Eurofor's (European Operational Rapid Force) creation was made by France, Italy, Spain and Portugal. Eurofor became operation in June 1998 as a task force of the Western European Union.

Eastern borders
The Soviet Union should have its sphere of international influence, which could be the same as Warsaw Pact (of 1955) and Comecon (1949) and could limit eastern borders of the European Commonwealth (members of Warsaw Pact were Albania, Bulgaria, Czechoslovakia, German Democratic Republic, Hungary, Poland, Romania, Soviet Union).

Appearances in games
The European Commonwealth is mentioned only in the Fallout intro and the Fallout Bible. A pre-Fallout "Resource Wars" game set in collapsing Europe (during the U.K.'s invasions of the Middle East) is one of the games that J.E. Sawyer would like to make if he could do any game, regardless of money and developing time.
