Inner Six

The Inner Six, or simply "the Six", were the six founding member states of the European Communities. They were in contrast to the outer seven who formed the European Free Trade Association rather than engage in supranational European integration. Five of the outer seven later joined the European Communities.

The inner six are those who responded to the Schuman Declaration's call for the pooling of coal and steel resources under a common High Authority. The six signed the Treaty of Paris creating the European Coal and Steel Community on 18 April 1951 (which came into force on 23 July 1952). Following on from this, they attempted to create a European Defence Community: with the idea of allowing West Germany to rearm under the authority of a common European military command, a treaty was signed in 1952. However the plan was rejected by the Senate of France, which also scuppered the draft treaty for a European Political Community (which would have created a political federation to ensure democratic control over the new European army). President of the ECSC High Authority, and architect of the ECSC, Jean Monnet resigned in protest and began work on a new plan concentrating on economic fields.

Dependency on overseas oil and the steady exhaustion of coal deposits led to the idea of an atomic energy community (a separate Community was favoured by Monnet, rather than simply extending the powers of the ECSC as suggested by the Common Assembly). However, the Benelux countries (Belgium, the Netherlands, and Luxembourg) and Germany desired a common market (though opposed by France and Monnet). In order to reconcile the two ideas, both communities would be created. Thus, the six went on to sign the Treaties of Rome in 1957, establishing the European Economic Community and the European Atomic Energy Community. The institutions of these communities would later be merged in 1967, leading to them collectively being known as the "European Communities". The six would continue in their co-operation until 1973 when they were joined by two of the outer seven (UK and Denmark) and Ireland.
