Formation and Expansion (1958-1993)
The formation and expansion of the [European Union](/p/european-union), spanning the years from 1958 to 1993, mark a pivotal phase in the history of European integration, transforming the continent into a cohesive economic and political union. This era laid the foundation for what is known today as the European Union (EU).
Formation of the European Economic Community
The journey began with the signing of the [Treaty of Rome](/p/treaty-of-rome-1957) on March 25, 1957, which established the [European Economic Community](/p/european-economic-community) (EEC). This agreement, effective from January 1, 1958, was pivotal in creating a common market and fostering closer economic cooperation among the initial six member states: [Belgium](/p/belgium), [France](/p/france), [Italy](/p/italy), [Luxembourg](/p/luxembourg), [Netherlands](/p/netherlands), and [West Germany](/p/west-germany).
Institutional Development
The EEC established several institutions to oversee its operations, including the [Council of the European Economic Community](/p/council-of-the-european-union), a legislative body responsible for policy-making and coordination. The [European Commission](/p/european-commission) was tasked with implementing decisions, while the [European Parliament](/p/european-parliament) began to represent the populace's interests.
Expansion of Membership (1958-1993)
The EU's expansion between 1958 and 1993 was marked by several significant enlargements:
1973 Enlargement
The first enlargement occurred on January 1, 1973, when [Denmark](/p/denmark), [Ireland](/p/ireland), and the [United Kingdom](/p/united-kingdom) joined the EEC, increasing its membership to nine countries and enhancing its economic strength and geographical reach.
1981 and 1986 Enlargements
[Greece](/p/greece) became a member on January 1, 1981, following its transition to [democracy](/p/democracy), marking the EEC's first expansion in the Mediterranean region. The subsequent enlargement on January 1, 1986, saw [Spain](/p/spain) and [Portugal](/p/portugal) joining the union, further solidifying the EEC's influence in Southern Europe.
Toward the European Union
The [Single European Act](/p/single-european-act), signed in 1986, was a pivotal amendment that sought to create a single market by 1992. This act bolstered economic cooperation and laid the groundwork for the transition to the European Union. The culmination of these efforts was the [Maastricht Treaty](/p/maastricht-treaty-1992), signed on November 7, 1991, and effective from November 1, 1993, which formally established the European Union.
Path to Further Expansion
The formation of the EU in 1993, coupled with its foundational treaties, paved the way for subsequent enlargements, including the notable [2004 enlargement](/p/2004-enlargement-of-the-european-union), which significantly increased the union's size and diversity.
