when did great britain join the european union
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]
Russia–United Kingdom relations The two countries fought each other (albeit only with some very limited naval combat) during the Anglo-Russian War (1807–12), after which Britain and Russia became allies against Napoleon in the Napoleonic Wars. They both played major cooperative roles at the Congress of Vienna in 1814-1815.
