European integration also grew after World War II. In 1949 the Council of Europe was founded, following a speech by Sir Winston Churchill, with the idea of unifying Europe to achieve common goals. It includes all European states except for Belarus and Vatican City. The Treaty of Rome in 1957 established the European Economic Community between six Western European states with the goal of a unified economic policy and common market. In 1967 the EEC, European Coal and Steel Community and Euratom formed the European Community, which in 1993 became the European Union. The EU established a parliament, court and central bank and introduced the euro as a unified currency. Between 2004 and 2013, more Central and Eastern European countries began joining, expanding the EU to 28 European countries, and once more making Europe a major economical and political centre of power. However, the United Kingdom withdrew from the EU on 31 January 2020, as a result of a June 2016 referendum on EU membership.
