In September 1956 just before the Suez Crisis. French Prime Minister Guy Mollet met up with British Prime Minister Anthony Eden in London. Mollet proposed a union between the United Kingdom and the French Union with Elizabeth II as head of state and a common citizenship. As an alternative, Mollet proposed that France join the Commonwealth. British Prime Minister Anthony Eden rejected both proposals and France went on to join the Treaty of Rome, which established the European Economic Community and strengthened the Franco-German cooperation. * The Union's Timeline * List of Nations
