Roots of the EU were sown during the Second World War. Post the Second World War they decided that need to stop this mass killing as well as the destruction from occurring in the future. Post this war, Europe split into the West and East Europe. The nations in the Western region formed a council of Europe in the year 1949. It was the initial step and they wanted to expand their council. The main members of this council were France, Germany, Luxembourg, Belgium and Netherlands. These nations entered into different business agreements for developing their industries. They signed the Coal and Steel treaty. Then they started a common agricultural policy and took steps to increase the trade activity. These nations also removed the customs duty on the goods which were imported as well as exported between the nations. In order to maintain the monetary stability they started making plans for a single currency during the 1970s. In 1972 they decided that their currencies will fluctuate only within certain narrow limits. Thereafter in the year 1974 they set up a European Regional Development Fund which transferred money to smaller and poorer nations to develop their infrastructure. In the year 1979 citizens got to elect their leaders for the first time who will sit in the European Parliament. In the year 1981 Greece joined the European Union. Then came Spain and Portugal. Thus the European Union was expanding and the council was coming out with new treaties which were benefitting the European nations.
