The EU and European citizenship were established when the Maastricht Treaty came into force in 1993.

Hmmm, 2020 - 1993 = 27 years. LOL.

The European Union was formed in 1951 as the European Steel and Coal Community. It became the European Community in 1967.

A French veto under de Gaulle blocked British membership but when he left in 1969, a British application to join succeeded in 1972.

On January 1, 1973, the UK became a member.
