Enlargement of the European Union The EU's predecessor, the European Economic Community,[1] was founded with the Inner Six member states in 1958, when the Treaty of Rome came into force. Since then, the EU's membership has grown to twenty-eight, with the latest member state being Croatia, which joined in July 2013. The most recent territorial enlargement of the EU was the incorporation of Mayotte in 2014. The most notable territorial reductions of the EU, and its predecessors, were the exit of Algeria upon independence in 1962 and the exit of Greenland in 1985.
History of European Union–United Kingdom relations The Treaty of Accession was signed in January 1972 by the then prime minister Edward Heath, leader of the Conservative Party.[7] Parliament's European Communities Act 1972 was enacted on 17 October, and the UK's instrument of ratification was deposited the next day (18 October),[8] letting the United Kingdom's membership of the EC come into effect on 1 January 1973.[9]
