The European Federation, also referred to as the United States of Europe (USE), European State, or Federal Europe, is the hypothetical scenario of European integration leading to the formation of a sovereign superstate (similar to the United States of America), organised as a federation of the member countries of the European Union (EU), as contemplated by political scientists, politicians, geographers, historians, futurologists and fiction writers. At present, while the EU is not a federation, various academic observers regard it as having some of the characteristics of a federal system.
Ideas of European unity before 1948 and History of the European Union
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 Poděbrady 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 Jastrzębowski 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.
