This is when all of Europe becomes united under a single powerful government that either supersedes or in extreme cases supplants the traditional national governments of Europe. Usually, the government in question takes the form of an expanded version of UsefulNotes/TheEuropeanUnion, or is a clear {{Expy}} thereof. This trope is often found in stories that take place TwentyMinutesIntoTheFuture.

The dream of a United Europe was very real in [[TheFifties the 1950s]] after UsefulNotes/WorldWarII -- the idea of the mainland throwing off prejudice and becoming one massive super-country. There is also presumably a connection being drawn by some people with the rise of the USSR and USA -- to them, it 'makes sense' that there should be a United States of Europe to join it. Today, that [[TheFifties 1950s]] dream is more widespread than it has ever been, but, naturally, blocks still remain - like the fact that Europeans have been kicking the hell out of each other for 2500 years and have only really considered stopping since 1945. Looking back through history, it's hard to find a period of more than a couple of years in a row in the last millennium when there wasn't a war in Europe, with the likes of England vs Scotland, England vs Ireland, England vs France, England vs Spain, Spain vs the Netherlands, Spain vs France, Denmark vs Sweden, Poland vs Germany, Poland vs Russia, Russia vs Germany, Germany vs Germany, and the usual internecine Balkan strife, rolling around with such regularity that they practically qualify as annual derbies. More recent editions include Everyone vs Germany and Everyone vs Russia.

As a result, a lot of previous attempts to unify Europe have been through force: See [[UsefulNotes/HolyRomanEmpire Charlemagne]], [[UsefulNotes/LEtatCestMoi Louis XIV]], UsefulNotes/NapoleonBonaparte, and UsefulNotes/AdolfHitler as attempts to violently unify Europe, or at least, large parts of it. Oh yeah, there's also AncientRome, which actually succeeded in unifying much of what is now southern and western Europe and was the example many of the aforementioned leaders sought to emulate. As a result, there are a lot of grudges that are centuries, even millennia, old, and a lot of fearsomely independent-minded states that are exceptionally jealous of their sovereignty.

In RealLife, the UsefulNotes/EuropeanUnion is a free-trade area that has gradually evolved to include 'common policy' in areas such as agriculture, standards, border controls, etc etc etc, and has many characteristics of [[TheFederation a federation]], like a common currency throughout most member states,[[note]]Great Britain and most of Scandinavia are in the EU but not the Eurozone[[/note]] an elected parliament, a motto [[note]]("United in diversity")[[/note]], [[http://en.wikipedia.org/wiki/Anthem_of_Europe an anthem]] and a court of justice (while technically, it remains at best a confederation due to states remaining independent). While some have called it a [[http://en.wikipedia.org/wiki/Federation#Alleged_de_facto_federations de facto federation]], it is still a long way off being one country, and there is still a great amount of debate about the subject between people who are opposed to expanding the European Union's power - or even want to see it rolled back in certain areas (called Eurosceptics) and those who are in favour of further political integration (called Eurofederalists). Likewise, there is debate on exactly ''how'' the EU is supposed to be run, considering how its structure is unlike that of the USA.

A recurring phenomenon in this trope, especially if the creator is British or American, is that [[UsefulNotes/WithEuropeButNotOfIt Britain]] will somehow not be part of a United Europe.[[note]]Which is a lot more plausible as of the vote by the UK electorate to leave the EU on 23 June 2016. Prior to then, although Britain was considered the most Eurosceptic country, the political and business elites strongly supported continued EU membership and have always been willing to go along with EU integration - albeit usually with opt-outs from certain measures.[[/note]] [[FridgeLogic Oddly enough]], the very independent and politically neutral UsefulNotes/{{Switzerland}}, as well as UsefulNotes/{{Norway}} (neither of which are even in the EU) rarely get the same treatment. It should come as no surprise therefore that this trope varies depending on who's making the work in question. Another recurring phenomenon is that the capital of the United Europe rarely stays as Brussels, usually moving to Paris or Berlin, probably because audiences can easily recognize these landmark-heavy locations over the less-visited Brussels.

Whether this is destined to be TruthInTelevision or not, as well as whether it ''ought'' to be, depends on who you ask. It remains a ''very'' contentious issue on both sides. Let's just say that the EU isn't especially popular in the UK (especially considering that the country has experienced [[http://archive.is/8VLSP an economic boom]] since the Brexit vote[[note]]YMMV on this, depending on who you ask, consdidering that the referendum result in favour of leaving was a marginal win by 52:48 for the anti-EU faction, and factoring in that some UsefulNotes/BritishNewspapers with an agenda of their own are talking up slight indicators of a boom to justify their somewhat fervent pro-Brexit positions, combined with very real and noticeable drops in the value of the pound, leaves the future a lot more uncertain. Especially since Brexit hasn't actually ''happened'' yet, it's just been agreed to do it. It's far to early to tell what the economic impact will be once the split is actually finalized, especially since the exact details (as in, whether the EU will be willing to negotiate favorable trade deals with the UK or attempt to punish them for leaving via heavy tariffs) are still under negotiation, and there's the additional prospect that Scotland (which voted 62:38 in favor of remaining in the EU, without even a single town or county having an anti-EU majority, and already had a strong anti-UK nationalist faction) might declare independence in order to rejoin the EU and take most of the UK's oil with them.[[/note]]) or present-day Greece, and everywhere else the mention of it being a good/bad thing can spark a rather fierce argument down at the pub if you aren't careful. RuleOfCautiousEditingJudgement may well apply.

[[folder:Anime and Manga]]
* ''Franchise/CodeGeass'' has an European Union which was founded after its version of the French Revolution was able to successfully sweep across the entire continent, including even Great Britain. In this alternate timeline, Napoleon was a victorious general but there are conflicting versions about his fate. One story says the British royal family had him assassinated as they fled to the still-loyal American colonies, while the Europeans themselves claim that he was executed by his own people in order to prevent him from establishing a dictatorship. The E.U. was also the only one out of the three original superpowers that was democratic.
** While the E.U. is mostly in the background in [[Anime/CodeGeass the original show]], ''Anime/CodeGeassAkitoTheExiled'' is set entirely in Europe, and shows us the continent isn't as united as it sounds. The major conflict in the OVA series is between the United Republic of Europia (which is most of Western and Central Europe with its capital in Paris) vs. Euro Britannia, which remains loyal to the Holy Britannian Empire (consisting mainly of Eastern Europe and Russia, with its capital in St. Petersburg). The major battles in the series take place in Poland and Belarus, which is the front line of the European theater of war.
* ''Franchise/{{Gundam}}'' has several examples.
** ''Anime/MobileSuitGundamSEED'' and ''Anime/MobileSuitGundamSEEDDestiny'' has the Eurasian Federation, a member of the Earth Alliance which (unusually for this trope) includes all of Russia and the Middle East as well as Europe proper.
** ''Anime/MobileSuitGundam00'' gives us the Advanced European Union as one of the world's three superpowers, which is (as the name suggests) basically the European Union TwentyMinutesIntoTheFuture.
* In Creator/NaokiUrasawa's ''Manga/{{Pluto}}'' the EU has evolved into the European Federation and expanded to include Turkey.
* While it's not the EU, ''Anime/MobileSuitGundamWingEndlessWaltz'' reveals that the [[TheFederation Earth Sphere]] [[OneWorldOrder Unified Nation]]'s capital is Brussels, Belgium. Though that said, the ESUN does have a decidedly European flavor.

[[folder:Comic Books]]
* ''ComicBook/JudgeDredd'': Europe is usually said to have two different Mega Cities: Brit Cit and Euro Cit.[[note]]Ireland could also be counted as a separate entity, but that's a whole 'nother story: [[TheThemeParkVersion it's literally a giant theme park]].[[/note]] So, the Britons are still independent, but the rest of the continent (or whatever's left of it after the Great Atomic War) is implied to be unified in one polity.

[[folder:Films -- Animation]]
* The European Confederation is mentioned as the place where all the action happens in ''Anime/TheSkyCrawlers'', but this isn't elaborated further. Maps still seem to have national borders drawn on them, but they are crossed by private military forces without incident or even mention.

* A.J. Butcher's ''Literature/SpyHigh'' has a united Europe called "Europa".
* Eric Flint's ''Literature/SixteenThirtyTwo'' series features a 'United States of Europe' though it is actually more of a United States of Germany, plus bits of OTL France, Denmark, Poland, and Austria.
* ''Literature/{{Incompetence}}'' by ''Series/RedDwarf'' creator Rob Grant, where stupidity is a constitutionally protected right.
* ''The Late, Great Planet Earth'' by Hal Lindsey was a work of fundamentalist Christian eschatology predicting a united Europe ruled over by TheAntichrist. This became a fairly common expectation among the US Christian Right for much of the eighties and nineties, until [[TheWarOnTerror Islam became the new bogey.]]
* In Creator/GeorgeOrwell's ''[[Literature/NineteenEightyFour 1984]]'', all of continental Europe and part of (mostly northern) Asia were united in one nation, called appropriately enough "Eurasia", while Great Britain was a part of "Oceania", which consisted of the territories of the Americas and the former British Empire. (Orwell borrowed the vision of a British-American fusion and a Eurasian USSR from the writings of James Burnham, but his own preferred plan was uniting Britain with the other Western European states, minus their colonies, into a democratic Socialist federation.)
* In Andrew Roberts' ''The Aachen Memorandum'', the United Kingdom regains its independence after being under the thumb of a corrupt and dictatorial European Union.
* In the ''Hex'' series of novels set TwentyMinutesIntoTheFuture, the main characters are fighting against/fleeing from the forces of the corrupt European Federation.
* In Creator/OrsonScottCard's AlternateHistory series ''[[Literature/TheTalesOfAlvinMaker Alvin Maker]]'', Napoleon suceeds in this by not engaging in his disastrous invasion of Russia and declaring a unilateral cease-fire with Britain.
* In John Barnes' ''Mother of Storms'' the European Union has both become more cohesive and taken a racist turn, expelling everyone of non-European descent. By the end of the book it's started to come apart at the seams due to the eponymous crisis.
* In Creator/TomKratman's ''Literature/{{Caliphate}}'', Western Europe becomes mostly Islamic, under the control of the eponymous Caliphate. The British Isles and Switzerland, however, are not under Islamic control.
* Peter F. Hamilton's ''Great North Road'' has Grande Europe.
* Played with in the ''Literature/StarCarrier'' series. The Paneuropean Federation appears to be this, except the various nationalities are still bickering constantly. Very few think of themselves as "European" (or "Paneuropean") but still as British, French, Polish, German, etc.
* In Samantha Shannon's ''Literature/TheBoneSeason'' SCION controls nine European nations, not all of them named (Britain, Ireland, France, Greece, Serbia and Sweden are). How much autonomy the various countries' governments have isn't really gotten into although Britain and Ireland are completely under its control.
* In the Literature/LeftBehind series, most of continental Europe becomes the United European States during the time of the Tribulation, with Greece and Romania becoming part of the United Carpathian States.
* AlternateHistory classic ''Literature/ForWantOfANail'' depicts this as a minor detail to its main focus (North America following a failed UsefulNotes/AmericanRevolution) when the German Empire conquers continental Europe and the Middle East during the Global War.
* Europe is, for all intents and purposes, one political entity in Creator/VladimirVasilyev's ''Literature/WolfishNature''. This is in contrast to the US (Alaska split off), Canada (split in two), and Russia (Siberia split off). Additionally, there's a MiddleEasternCoalition of sorts, and a barely-mentioned nation called Sinojapan.
* Gareth L. Powell's ''[=AcK Ack Macaque=]'' series takes place in an AlternateHistory with a European Commonwealth dominated by the United Kingdom of Britain, France, Northern Ireland and Norway.
* Zigzagged in Wolfgang Jeshke's ''The Cusanus Game''. In the main timeline the EU is falling apart in 2052. However Austria-Hungary exists once more and has annexed Slovenia and parts of northern Italy. In the alternate timeline there is a United Europe consisting of everything west of Russia and the Dardenelles which is highly isolationist.
* Implied to be the case in the first ''Literature/ArrivalsFromTheDark'' novel, where the three power blocs that finance the [[SpaceNavy United Space Forces]] are the [[ExpandedStatesOfAmerica United States and Canada]] (USC), the Eurasian Union (Russia), and the EU. China, the Middle East, and the rest of the world are kept out of space. This trope then flows into OneWorldOrder between the first and second novels (a 37-year gap), where the UN is turned into the more powerful World Parliament. Later, this lays the foundation for the [[TheFederation Earth Federation]], as humanity expands to other star systems and establishes colonies.

[[folder:Live-Action TV]]
* ''Series/StarTrekTheNextGeneration'' has mentioned both a United States of Europe and a European Alliance.

[[folder:Tabletop Games]]
* Creator/WhiteWolf's ''TabletopGame/{{Scion}}'' RPG, though set in the ''present day'', actually has EU Armed Forces, which the EU does not have although whether it should remains a matter of discussion. In all fairness, said EU Armed Forces were in a story in which the end of the world was in full swing and it is entirely possible that such a situation might cause a united response from Europe.
* The main superpower of the world in ''TabletopGame/{{Cyberpunk}} 2020'' (by virtue of both economics and a [[{{BFG}} huge]] [[MagneticWeapons lunar-based railgun of mass destruction]]) is an expy of the EU.
* ''TabletopGame/TranshumanSpace'' has an expanded EU (including Montreal), but only slightly increased powers (the main one being the Genetic Regulation Agency, which polices the Europe-wide ban on bioroid slavery). Several sourcebooks note that Europe has very few federal powers.
* In Steve Jackson Games' wargame ''TabletopGame/{{OGRE}}'', the Paneuropean Federation is this. In the ExpandedUniverse, its conquest of Britain is a major turning point, because this gives it the designs to create the eponymous [[TankGoodness supertank]].
* Partially averted in Ground Zero Games' 'verse (used for the miniatures games ''TabletopGame/FullThrust'', ''[[TankGoodness Dirtside II]]'' and ''[[TheSquad Stargrunt II]]'': Europe has actually split into the New Swabian League (Germany and Austria), the Federal States of Europe (France, Spain, Italy), and the Scandanavian Federation (Denmark, Norway, Sweden, and a reluctant Finland). Britain, meanwhile, is part of the New Anglian Confederation (which also includes the US and Canada).
* ''Neo Tech'' has a European superstate (and a separate Scandinavian Union, and Madagasque superpower, but that's a different story entirely).
* The cyberpunk setting ''Neurospasta'' has a politically united EU, along with a coalition of Middle-Eastern states and an economic alliance of eastern Pacific nations, as the new world superpowers, having backed the correct form of sustainable energy in the wake of a global ecological catastrophe. The USA, which supported the technology that didn't become standard, has become isolationist and largely irrelevant to the world stage.

[[folder:Video Games]]
* ''VideoGame/HeartsOfIronII'' mod modern day scenario has an event where the EU unites to one country as well... it also becomes a hyperpower the moment that happens since you get way more production/resources/manpower/research than anyone else...
* The EU from ''[[VideoGame/{{Battlefield}} Battlefield 2142]]''.
* The ''[[VideoGame/{{Battlefield}} Battlefield 2]]'' expansion ''Euro Force'' features an EU Army, which implies a somewhat more unified Europe than today.
* In ''VideoGame/FrontMission'', the "European Commonwealth" is the oldest superstate (the others being the OCU which includes most nations of the Pacific Ocean, and the USN, which is the US except that now all of the Americas are part of it) in Front Mission 4, its leaders are presented as fairly incompetent, and in Front Mission 3, which happens after [=FM4=], Europe is presented as an economical superpower, but do not act directly in the story.
* In Creator/TomClancy's ''VideoGame/EndWar'', the European Federation is one of three playable factions, being thrown into WorldWarIII because of the Russians tampering with a European satellite.
** Interestingly enough, the only major countries left outside the EF are the [[UsefulNotes/TheCommonwealthOfNations New Commonwealth]] (the result of Ireland and the UK leaving the Union) and Switzerland.
* A mod for ''VideoGame/{{Civilization}} IV'' included in the ''Beyond the Sword'' expansion has one of the four global factions of the far future be "Europa". Doesn't include Britain, which is part of America, Inc, but does include northern Algeria for some reason.
** It basically ''is'' ''Literature/NineteenEightyFour'', but with another State; Algeria is there because of the France connection, no doubt.
* ''VideoGame/MassEffect2'' gives this a nod - Earth is still run by various nations, but the only powers ever talked about are China, an expanded and reorganized United States of America (now including Canada, Mexico, and the Caribbean islands), and the European Union. By 2186, the United Kingdom is implied to ''still'' be a [[UsefulNotes/WithEuropeButNotOfIt seperate entity]] from the European Union however.
* A mod for ''VideoGame/EuropaUniversalis 3'' allows you to create the European Union by taking control of the capitals of the EU as it is right now (that is, Lisbon, Madrid, London, Paris, Rome, Berlin...). Uniting Europe is also a [[SelfImposedChallenge common goal for veteran players]].
* The United States of Europe in ''Endgame''. However, [[NotEvenBotheringWithTheAccent the characters have American accents]].
* In ''VideoGame/{{Fallout}}'', the European Commonwealth is clearly an analogue to the real world European Union, except it seems to be a much stronger military alliance rather than the Union's focus on economic cooperation.
* One of the main factions in ''VideoGame/CommandAndConquer2013'', with their appearance and [[ACommanderIsYou game-play style]] making them a CaptainErsatz of the first game's [[UsefulNotes/YanksWithTanks USA faction]], after [[CulturalCringe fan hatred]] saw the U.S. getting terrorized and retreating from Europe to secure the home-front in the first game's expansion pack.
** In the (official) backstory of the Tiberium universe, the Allied Nations basically became this, and eventually, the GDI, after [[VideoGame/CommandAndConquerRedAlert Stalin's assault]] forced them to band together.
* In the VideoGame/{{Earth 2150}} series, the Eurasian Dynasty is [[ExactlyWhatItSaysOnTheTin a united Europe and Asia.]]
* It's not stated in ''VideoGame/ShatteredUnion'', but the forces sent to the DividedStatesOfAmerica to stop the civil war are made up of units from various European countries under a single command structure.

[[folder:Web Comics]]
* In Webcomic/GirlGenius the Wulfenbach Empire controls a large piece of Europe. How much is vague but apparently most or all of central and eastern Europe. In the novelization ''Agatha H and the Clockwork princess'' a footnote mantions that it stretches "from the Atlantic to Istanbul".

[[folder:Web Original]]
* In WebOriginal/OrionsArm not only does the [[DividedStatesOfAmerica US divide]] but the EU eventually develops into the European Federation, but that isn't mentioned much as most of the interesting stuff happens thousands of years after humanity is driven off earth.
* The German-dominated Greater European Economic Union or GEEU for short in ''Literature/DecadesOfDarkness'' unites most of Europe outside [[TheFederation the Russian Federation]].
* The German-controlled Northern European Alliance in ''Literature/WeimarWorld'' from Website/AlternateHistoryDotCom is pretty much this.

* One newspaper opinion comic titled "Neue Weltordnung?[[labelnote:*]]New world order?[[/labelnote]]" showed a pair of maps labeled 'before' and 'after', depicting the end of the UsefulNotes/ColdWar. The first showed the patchwork of European countries abutting the Soviet Union, while the second showed a patchwork of ex-Soviet countries abutting the new European Union.
* Music critic and analyst Simon Reynolds said this of {{trance}} music in the early 2000s.
