European integrationEuropean integration is the process of industrial, economic, political, legal, social, and cultural integration of states wholly or partially in Europe or nearby. European integration has primarily come about through the European Union and its policies. In antiquity, the Roman Empire brought about integration of multiple European and Mediterranean territories. The numerous subsequent claims of succession of the Roman Empire, even the iterations of the Classical Empire and its ancient peoples, have occasionally been reinterpreted in the light of post-1950 European integration as providing inspiration and historical precedents.
European FederationThe 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.
Economic integrationEconomic integration is the unification of economic policies between different states, through the partial or full abolition of tariff and non-tariff restrictions on trade. The trade-stimulation effects intended by means of economic integration are part of the contemporary economic Theory of the Second Best: where, in theory, the best option is free trade, with free competition and no trade barriers whatsoever.
