1986 - 1986

Portugal becomes a Member of the EEC – European Economic Community

On 12 June 1985 Portugal signed the treaty of accession to the EEC-European Economic Community. The Prime Minister Mário Soares led the entourage that formalized, in the Jerónimos Monastery, the country’s entrance in the european project.
In fact, Portugal has been a member of the European Union since 1 January 1986, after submitting its candidature for membership on 28th March 1977 and signing the pre-accession agreement on 3rd December 1980.
Portugal’s accession to the EEC is one of the consequences of April 25, 1974 and the subsequent changes that this revolution caused in the economic, political, and social aspects.
