As early as 1951 there was the European Coal and Steel Community, which was followed by the European Atomic Energy Community and then the European Common Market, which later integrated to become today's European Community. These developments led step by step to European Union. Their goal is to bring about a federal Europe, which would have a similar structure to that of the United States. This of course will take time.
現在歐洲整體而言，處在一個整合時期，最早是在一九五一年的煤鋼聯盟，然後歐洲原子能聯盟、歐洲共同市場，之後整合起來成為歐體，一步步發展到今天的歐洲聯盟，他們的目標是希望成為一個歐洲合眾國，類似美利堅合眾國這樣的構想，當然這還需要時間。
