The United States of Europe (USE), the Federal States of Europe (FSE), the European State, the European Superstate, the European Federation and Federal Europe are similar hypothetical scenarios of a single sovereign state in Europe (hence superstate), organised as a federation similar to the United States of America, as contemplated by political scientists, politicians, geographers, historians, futurologists, and fiction writers. At present, while the European Union (EU) is not a federation, various academic observers regard it as having some of the characteristics of a federal system.
Various versions of the concept have developed over the centuries, many of which are mutually incompatible (inclusion or exclusion of the United Kingdom, secular or religious union, etc.). Such proposals include those from Bohemian King George of Pod?brady in 1464; Duc de Sully of France in the seventeenth century; and the plan of William Penn, the Quaker founder of Pennsylvania, for the establishment of a "European Dyet, Parliament or Estates". George Washington also allegedly voiced support for a "United States of Europe", although the authenticity of this statement has been questioned.
Felix Markham notes how during a conversation on St. Helena, Napoleon Bonaparte remarked: "Europe thus divided into nationalities freely formed and free internally, peace between States would have become easier: the United States of Europe would become a possibility". "United States of Europe" was also the name of the concept presented by Wojciech Jastrz?bowski in About eternal peace between the nations, published 31 May 1831. The project consisted of 77 articles. The envisioned United States of Europe was to be an international organisation rather than a superstate. Giuseppe Mazzini, an early advocate of a "United States of Europe" regarded European unification as a logical continuation of the unification of Italy.  Mazzini created the Young Europe movement.
The term "United States of Europe" (French: États-Unis d'Europe) was used by Victor Hugo, including during a speech at the International Peace Congress held in Paris in 1849. Hugo favoured the creation of "a supreme, sovereign senate, which will be to Europe what parliament is to England" and said: "A day will come when all nations on our continent will form a European brotherhood ... A day will come when we shall see ... the United States of America and the United States of Europe face to face, reaching out for each other across the seas". Hugo planted a tree in the grounds of his residence on the Island of Guernsey and was noted in saying that when this tree matured the United States of Europe would have come into being. This tree to this day is still growing in the gardens of Maison de Hauteville, St. Peter Port, Guernsey, Victor Hugo's residence during his exile from France.
In 1867, Giuseppe Garibaldi and John Stuart Mill joined Victor Hugo at the first congress of the League of Peace and Freedom in Geneva. Here the anarchist Mikhail Bakunin stated: "That in order to achieve the triumph of liberty, justice and peace in the international relations of Europe, and to render civil war impossible among the various peoples who make up the European family, only a single course lies open: to constitute the United States of Europe". The French National Assembly also called for a United States of Europe on 1 March 1871.
"Under a capitalist regime, the United States of Europe are either impossible or reactionary."
Following the First World War, some thinkers and visionaries again began to float the idea of a politically unified Europe. In 1923, the Austrian Count Richard von Coudenhove-Kalergi founded the Pan-Europa Movement and hosted the First Paneuropean Congress, held in Vienna in 1926. The aim was for a Europe based on the principles of liberalism, Christianity and social responsibility. Before the communist revolution in Russia, Leon Trotsky foresaw a "Federated Republic of Europe -- the United States of Europe", created by the proletariat.
In 1929, Aristide Briand, French Prime Minister, gave a speech before the Assembly of the League of Nations in which he proposed the idea of a federation of European nations based on solidarity and in the pursuit of economic prosperity and political and social co-operation. At the League's request, Briand presented a "Memorandum on the organisation of a system of European Federal Union" in 1930. In 1931, French politician Édouard Herriot and British civil servant Arthur Salter both penned books titled The United States of Europe.
After the First World War, Winston Churchill had seen continental Europe as a source of threats and sought to avoid the United Kingdom's involvement in European conflicts. On 15 February 1930, Churchill commented in the American journal The Saturday Evening Post that a "European Union" was possible between continental states, but without the United Kingdom's involvement:
We see nothing but good and hope in a richer, freer, more contented European commonality. But we have our own dream and our own task. We are with Europe, but not of it. We are linked but not compromised. We are interested and associated but not absorbed.
During the 1930s, Churchill was influenced by and became an advocate of the ideas of Richard von Coudenhove-Kalergi and his Paneuropean Union, though Churchill did not advocate the United Kingdom's membership of such a union. (Churchill revisited the idea in 1946).
During the World War II victories of Nazi Germany in 1940, Wilhelm II stated that "the hand of God is creating a new world & working miracles. ... We are becoming the United States of Europe under German leadership, a united European Continent".
Churchill used the term "United States of Europe" in a speech delivered on 19 September 1946 at the University of Zurich, Switzerland. In this speech given after the end of the Second World War, Churchill concluded:
We must build a kind of United States of Europe. In this way only will hundreds of millions of toilers be able to regain the simple joys and hopes which make life worth living.
Churchill's was a more cautious approach ("the unionist position") to European integration than was the continental approach that was known as "the federalist position". The Federalists advocated full integration with a constitution, while the Unionist United Europe Movement advocated a consultative body and the Federalists prevailed at the Congress of Europe. The primary accomplishment of the Congress of Europe was the European Court of Human Rights, which predates the European Union.
The Union Movement was a British party founded by Oswald Mosley after the dissolution of his British Union of Fascists. Mosley first presented his idea of "Europe a Nation" in his book The Alternative in 1947. He argued that the traditional vision of nationalism that had been followed by the various shades of pre-war fascism had been too narrow in scope and that the post-war era required a new paradigm in which Europe would come together as a single state. In October 1948 when Mosley called for elections to a European Assembly as the first step towards his vision. Nation Europa was a German magazine inspired by Mosley's ideas, founded in 1951 by former SS commander Arthur Ehrhardt and Herbert Boehme with the support of Carl-Ehrenfried Carlberg.
Individuals such as the former German Foreign Minister Joschka Fischer have said (in 2000) that he believes that the EU must in the end become a single federation, with its political leader chosen by direct elections among all of its citizens. However, claims that the (then) proposed Treaty of Nice aimed to create a "European superstate" were rejected by former United Kingdom European Commissioner Chris Patten and by many member-state governments. (As of 2021 , the post "President of the European Union" does not exist, nor are there any plans that it should do so).
The member states of the European Union do have many common policies within the EU and on behalf of the EU that are sometimes suggestive of a single state. It has a common executive (the European Commission), a single High Representative for the Common Foreign and Security Policy, a common European Security and Defence Policy, a supreme court (European Court of Justice – but only in matters of European Union law) and an intergovernmental research organisation (the EIROforum with members like CERN). The euro is often referred to as the "single European currency", which has been officially adopted by nineteen EU countries while three other member countries of the European Union have linked their currencies to the euro in ERM II. Then non-EU member states of Andorra, Monaco, San Marino, and Vatican City concluded monetary agreements with the EU on the usage of the euro. The non-EU member states of Kosovo and Montenegro adopted the euro unilaterally.
Several pan-European institutions exist separate from the EU. The European Space Agency counts almost all EU member states in its membership, but it is independent of the EU and its membership includes nations that are not EU members, notably Switzerland and Norway. The European Court of Human Rights (not to be confused with the European Court of Justice) is also independent of the EU. It is an element of the Council of Europe, which like ESA counts EU members and non-members alike in its membership.
At present, the European Union is a free association of sovereign states (a de facto, but not de jure, confederation) designed to further their shared aims. Other than the vague aim of "ever closer union" in the Solemn Declaration on European Union, the EU (meaning its member governments) has no current policy to form a federal union. However, in the past Jean Monnet, a person associated with the EU and its predecessor the European Economic Community, did make such proposals. A wide range of other terms are in use to describe the possible future political structure of Europe as a whole and/or the EU. Some of them, such as "United Europe", are used often and in such varied contexts, but they have no definite constitutional status.
In the United States of America, the concept enters serious discussions of whether a unified Europe is feasible and what impact increased European unity would have on the United States of America's relative political and economic power. Glyn Morgan, a Harvard University associate professor of government and social studies, uses it unapologetically in the title of his book The Idea of a European Superstate: Public Justification and European Integration. While Morgan's text focuses on the security implications of a unified Europe, a number of other recent texts focus on the economic implications of such an entity. Important recent texts here include T. R. Reid's The United States of Europe and Jeremy Rifkin's The European Dream. Neither the National Review nor the Chronicle of Higher Education doubt the appropriateness of the term in their reviews.
Various federalist organisations have been created over time supporting the idea of a federal Europe. These include the Union of European Federalists, the European Movement International, the (former) European Federalist Party and Stand Up For Europe.
The Union of European Federalists (UEF) is a European non-governmental organisation campaigning for a Federal Europe. It consists of 20 constituent organisations and it has been active at the European, national and local levels for more than 50 years. A young branch called the Young European Federalists also exists in 30 countries of Europe.
The European Movement International is a lobbying association that coordinates the efforts of associations and national councils with the goal of promoting European integration, and disseminating information about it.
The European Federalist Party was a pro-European, pan-European and federalist political party from 2011 to 2016 which advocated further integration of the European Union.
As the successor movement of the European Federalist Party, Stand Up For Europe is a pan-European NGO that advocates the foundation of a European Federation. Contrary to movements like the UEF or the former EFP, Stand Up for Europe does not command any national levels anymore, but only consists of regional city teams and the European level.
Volt Europa is a pan-European, progressive movement that stands for a new and inclusive way of doing politics and that wants to bring change for European citizens. The party claims that a new pan-European approach is needed to overcome current and future challenges, such as - among others - climate change, economic inequality, migration, international conflict, terrorism, and the impact of the technological revolution on jobs. Volt says that national parties are powerless in front of these challenges, because they go beyond national borders and need to be tackled by Europeans, as one people. As a transnational party, it believes it can help the European people unite, create a shared vision and understanding, exchange good practices across the continent, and come up with working policies.
Following the negative referendums about the European Constitution in France and the Netherlands, the former Belgian prime minister Guy Verhofstadt released in November 2005 his book, written in Dutch, Verenigde Staten van Europa ("United States of Europe") in which he claims - based on the results of a Eurobarometer questionnaire - that the average European citizen wants more Europe. He thinks a federal Europe should be created between those states that wish to have a federal Europe (as a form of enhanced cooperation). In other words, a core federal Europe would exist within the current EU. He also states that these core states should federalise the following five policy areas: a European social-economic policy, technology cooperation, a common justice and security policy, a common diplomacy and a European army. Following the ratification of the Treaty of Lisbon (December 2009) by all member states of the EU, the outline of a common diplomatic service, known as the External Action Service of the European Union (EEAS), was set in place. On 20 February 2009, the European Parliament also voted in favour of the creation of Synchronised Armed Forces Europe (SAFE) as a first step towards a forming a true European military force.
Verhofstadt's book was awarded the first Europe Book Prize, which is organised by the association Esprit d'Europe and supported by former President of the European Commission Jacques Delors. The prize money was EUR20,000. The prize was declared at the European Parliament in Brussels on 5 December 2007. Swedish crime fiction writer Henning Mankell was the president of the jury of European journalists for choosing the first recipient.
While receiving the reward, Verhofstadt said: "When I wrote this book, I in fact meant it as a provocation against all those who didn't want the European Constitution. Fortunately, in the end a solution was found with the treaty, that was approved".
In 2012, Viviane Reding, the Luxembourgish Vice-President of the European Commission called in a speech in Passau Germany and in a series of articles and interviews for the establishment of the United States of Europe as a way to strengthen the unity of Europe.
The Italian Prime Minister Matteo Renzi said in 2014 that under his leadership Italy would use its six-month-long presidency of the European Union to push for the establishment of a United States of Europe.
In December 2017, Martin Schulz, who was then the new leader of the German Social Democratic Party, called for a new constitutional treaty for a "United States of Europe". He proposed that this constitution should be written by "a convention that includes civil society and the people" and that any state that declined to accept this proposed constitution should have to leave the bloc. The Guardian's view was that his proposal was "likely to be met with some resistance from Angela Merkel and other EU leaders". On that day he also stated that he would like to see a "United States of Europe" by 2025.
In 1992, Dutch businessman Freddy Heineken, after consulting with historians of the University of Leiden, Henk Wesseling and Willem van den Doel published a brochure "United States of Europe, Eurotopia?". In his work he put forward the idea of creating the United States of Europe as a confederation of 75 states that would be formed according to an ethnic and linguistic principle with a population of 5 to 10 million people.
Some people, such as T.R. Reid, Andrew Reding and Mark Leonard, have argued that the power of a hypothetical United States of Europe could potentially rival that of the United States of America in the twenty-first century. Leonard cites several factors: Europe's large population, the scale of the combined Europe's economy, Europe's low inflation rates, Europe's central geographic location in the world, and certain European countries' relatively highly developed social organisation and quality of life (when measured in terms such as hours worked per week and income distribution). Some experts[who?] claim that Europe has developed a sphere of influence called the "Eurosphere". Assumptions about a potential full or near superpower status of a perceived Supra-national Euro state are hypothetical in nature and on the other hand contrary notions and arguments exist across a wide spectrum among analysts, experts and pundits. 
Some people think that the European Union is unlikely to evolve into a unified federal superstate, due to political opposition of some members. Norwegian foreign policy scholar and commentator Asle Toje has argued that the power and reach of the European Union more closely resembles a small power. In his book The EU As a Small Power, he argues that the EU is a response to and function of Europe's unique historical experience in that the EU contains the remnants of not one but five past European orders. Although the 1990s and early 2000s have shown that there is policy space for greater EU engagement in European security, the EU has been unable to meet these expectations.
Asle Toje expresses particular concerns over the EU's security and defence dimension Common Security and Defence Policy, where attempts at pooling resources and forming a political consensus have failed to generate the results expected. These trends, combined with shifts in global power patterns, are seen to have been accompanied by a shift in EU strategic thinking whereby great power ambitions have been scaled down and replaced by a tendency towards hedging vis-à-vis the great powers. The author uses the case of the EUFOR intervention in Darfur and Chad to illustrate that the EU's effectiveness is hampered by a consensus-expectations gap, owing primarily to the lack of an effective decision-making mechanism. In his view, the sum of these developments is that the EU - in the current situation - will not be a great power and is taking the place of a small power in the emerging multi-polar international order.
The European Union does not include every nation in Europe and there is no consensus among the existing member state governments towards becoming even a loose confederation. Specifically, the term "United States of Europe" - as a direct comparison with the United States of America - would imply that each of the European states would acquire a status similar to that of a U.S. state, becoming constituent parts of a European federation acting as one sovereign country.
At the end of January 2020, the United Kingdom left the European Union.
Two thirds of respondents think that the EU (instead of a national government alone) should make decisions on foreign policy and more than half of respondents think that the EU should also make decisions on defense.
44% of respondents support the future development of the European Union as a federation of nation states, 35% are opposed. The Nordic countries were the most negative towards a united Europe in this study, as 73% of the Nordics opposed the idea. A large majority of the people for whom the EU conjures up a positive image support the further development of the EU into a federation of nation states (56% versus 27%).
In the fictional universe of Eric Flint's best selling alternate history 1632 series, a United States of Europe is formed out of the Confederation of Principalities of Europe, which was composed of several German political units of the 1630s.
Science fiction has made particular use of the idea: Incompetence, a dystopian novel by Red Dwarf creator Rob Grant, is a murder mystery political thriller set in a federated Europe of the near future, where stupidity is a constitutionally protected right. References to a European Alliance or European Hegemony have also existed in episodes of Star Trek: The Next Generation (1987-1994). In the Spy High series of books for young adults, written by A. J. Butcher and set around the 2060s, a united Europe exists in the form of "Europa", and Andrew Roberts's 1995 book The Aachen Memorandum details a United States of Europe formed from a fraudulent referendum entitled the Aachen Referendum.
Since the 2000s a number of computer strategy games set in the future have presented a unified European faction alongside other established military powers such as the United States and Russia. These include Euro Force (a 2006 expansion pack to Battlefield 2) and Battlefield 2142 (also released in 2006, with a 2007 expansion pack). In Battlefield 2142 a united Europe is shown as one of the two great superpowers on Earth, the other being Asia, despite being mostly frozen in a new ice age. The disaster theme continues with Tom Clancy's EndWar (2009), in which a nuclear war between Iran and Saudi Arabia, destroying the Middle Eastern oil supply, prompts the EU to integrate further as the "European Federation" in 2018. One game not to make bold claims of full integration is Shattered Union (2005), set in a future civil war in the United States, with the EU portrayed as a peacekeeping force. The video game series Wipeout instead makes a clear federal reference without a military element: one of the core teams that has appeared in every game is FEISAR. This acronym stands for Federal European Industrial Science and Research. In the video game series Mass Effect set in the 22nd century, the European Union is a sovereign state.
In the backstory of the Fallout series, several European nations joined together after the end of the Second World War, becoming known as the European Commonwealth. Heavily dependent on oil imports from the Middle East, the Commonwealth began a military invasion of the region in April 2052 once oil supplies began to run dry. This marked the beginning of the Resource Wars. After the oil dried up completely in 2060 and both sides were left in ruins, the Commonwealth collapsed into civil war as member states fought over whatever resources remained. It is not specified whether the European Commonwealth is a single federated nation or just an economic bloc similar to the EU.
In the anime series Code Geass, the EU (short for Euro Universe or Europia United), also known as the United Republic of Europia, is one of the three superpowers that dominate the Earth militarily, politically, culturally and economically. The political worldbuilding of the series partially resembles that of George Orwell's Nineteen-Eighty-Four, with three superstates in roughly the same geographic positions controlling the world.

On the table is the abolition of our national veto in 39 more aspects of legislative competence, a plan to give the EU its own national identity, the creation of a "single judicial space" and further moves to develop the EU's own defence and foreign policy, with plans eventually to create a European army. There can be no doubt about it. The plan is to create a European superstate.
