In this paper we researched European Union starting with the Agreement from Maastrich from year 1992, even though the European Union has a long traditional history and its origin is founded on regulations of economical integrations in Europe beginning from the 1950’s through the Roman treaty from year 1957 and the forming of the European Union Committee in year 1965. Further we follow her expansion and introduction of the European economic and monetary policy, to last, the joining perspective of Croatia. According to the Agreement from Maastrich, European Union lies on three posts: 1) Legal-political and regulative post, 2) Economical post, where the forming of European economical and monetary policy is in the first plan, especially the introducing of Euro as the unique European currency, 3) Post of Mutual foreign security policy within European Union. In that context we need to highlight the research conducted here and in European Union, including the world, regarding development of European Union and its economical, legal, political and cultural, as well as foreign diplomatic results, which are all perspectives of European Union. All the scientists and researches which were involved in exploring the development of EU with its modern tendencies and development perspective, agree that extraordinary results are achieved regards to economical, legal, political, foreign-security and diplomatic views, even tough many repercussions exist in progress of some particular members and within the EU as a whole. The biggest controversy arises in the perspective and expanding of European Union regarding ratification of the Constitution of EU from particular country members, but especially after the referendum was refused from two European countries, France and Netherlands. According to some estimates, the Constitution of EU would have difficulty to be adopted in Switzerland and some other Scandinavian countries, but also in Great Britain and other very developed countries. However the European Community and European Union were developing and expanding towards third European countries, regardless of Constitutional non-existence, where we can assume that if and when the Constitution of EU will be ratified, the EU will further develop as one of the most modern communities. This will enable economical development, especially development of European business, unique European market and free trade of goods and services, market of financial capital and labour market in free movement of labour. Being that EU has become one of the most largest dominating markets in the world, it offers a possibility to all new members to divide labour by using modern knowledge and high technology which insure economical, social and political prosperity. This results to forming a society of European countries which will guarantee all rights and freedom of development for all nations and ethnic groups. As well as, all European countries with somewhat less sovereignty, but in international relations will be stronger and significant, not only in sense of economics, but also in politics and military diplomatic relations. Therefore, Croatia has no choice and perspective if she does not join the European Union till year 2010, but until than it needs to create its strategy of economical and scientific-technological development, including demographic development, which will insure equal progress of Croatia as an equal member of European Union.
