Pan-European identity is the sense of personal identification with Europe, in a cultural, racial or political sense. The concept is discussed in the context of European integration, historically in connection with hypothetical proposals, but since the formation of the European Union (EU) in the 1990s increasingly with regards to the project of ever-increasing federalisation of the EU.
The model of a "pan-European" union is the Carolingian Empire, which united "Europe" in the sense of Latin Christendom. The original proposal for a Paneuropean Union was made in 1922 by Richard von Coudenhove-Kalergi. The term "Pan-European" is to be understood not as referring to the modern geographic definition of the continent of Europe but in the historical sense of the western parts of continental Europe sharing the common history of Latin Christendom, the Carolingian Empire and the early modern Habsburg Empire. Coudenhove-Kalergi saw the Pan-European state as a future "fifth great power", in explicit opposition to the Soviet Union, "Asia", Great Britain and the United States (as such explicitly excluding both the British Isles and Eastern Europe from his notion of "Pan-European").
The related concept Europeanism is the assertion that the people of Europe have a distinctive set of political, economic and social norms and values that are slowly diminishing and replacing existing national or state-based norms and values.
After 1945, an accelerating process of European integration culminated in the formation of the European Union (EU) in 1993. In the period of 1995–2013, the EU has been enlarged from 12 to 28 member states, far beyond the area originally envisaged for the "pan-European" state by Coudenhove-Kalergi (with the exception of Switzerland), its member states accounting for a population of some 510 million, or two thirds of the population of the entire continent.
