For a list of all Commonwealths in the Fallout universe, see Commonwealths.

The European Commonwealth is the Fallout universe's equivalent of the real-world European Union, which has integrated into a single state-like entity throughout Europe; this was probably a federal union. It is, however, unknown which European states were members.

In 2052, Europe was heavily dependent on oil imports from the petroleum-rich states of the Middle East and responded with military action to rapidly rising oil prices that were damaging its economy, starting the terrible global conflicts that later historians simply lumped together as the Resource Wars.

The outcome of the conflict suggests that the European Commonwealth possessed a unified military. It is unknown whether the Commonwealth took steps to ensure its survival like the United States did.

When the European Commonwealth-Middle East War came to an end in 2060, the Commonwealth began to dissolve as many countries withdrew from the state. A long civil war followed, lasting for an unknown period of time.

On globes and maps of the world in Fallout 4, it appears that the Mediterranean Sea has either dried up or was purposefully drained. While large maps found in pre-War bunkers in Fallout 4 with political boundaries drawn on them color the Mediterranean the same color as all other land masses and keep a drawn boundary around it, the antique globe which does not have political boundaries drawn does not include the Mediterranean Sea, with Southern Europe and North Africa fused together into one large Afro-Eurasian land mass. If the Mediterranean was purposefully drained during or before the Resource War by the European Commonwealth, this may be a reference to the project Atlantropa in which Europe drain the Mediterranean Sea for easier access to natural resources.


The European Commonwealth is mentioned only in the Fallout intro, the Fallout Bible and a Capitol Post article in Fallout 3.

A prequel to the Fallout series, Fallout: Resource Wars, set in a collapsing Europe (during the European Commonwealth's invasion 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 development time.[1]
