The 6 founding Member States of the EU's predecessor, the European Communities, established by the 1957 Treaties of Rome, were Belgium, France, Italy, Luxembourg, the Netherlands and the Federal Republic of Germany (West Germany). In 1973 Denmark, Ireland and the United Kingdom joined, enlarging the Communities to 9 Member States. The accession of Greece in 1981 brought their number up to 10 and it grew to 12 in 1986 when Spain and Portugal joined. By the 1990 German reunification the Communities also came to include the former German Democratic Republic (East Germany).
