The Eu, in its first incarnation initially consisted of the union of six countries, West Germany, France, Belgium, Luxembourg, Italy and the Netherlands, and was known as the European Coal and Steel Community. It was established after world war II as an attempt to increase European unity and centralise cola and steel trade works. Following World War II, the rife nationalism was perceived as a threat which required dissolution. It was the first organization to be based on the principles of supranationalism, which is a form of governance where the decisions made in the group are taken by elected representatives of each country. It was founded in 1951 by the Treaty of Paris, and was offered as a possible preventative measure against war between France and Germany.
In 1957, two more organisations were created, the European Economic Community and the European Atomic energy Community, and all three organizations were merged following the ratification of the Merger Treaty in 1967, after which point they were referred to collectively as the European Communities, or the European Community (EC) for short.
