Fears of a possible Communist takeover (especially in the United States) proved crucial for the first universal suffrage electoral outcome on 18 April 1948, when the Christian Democrats, under the leadership of Alcide De Gasperi, obtained a landslide victory. Consequently, in 1949 Italy became a member of NATO. The Marshall Plan helped to revive the Italian economy which, until the late 1960s, enjoyed a period of sustained economic growth commonly called the "Economic Miracle". In 1957, Italy was a founding member of the European Economic Community (EEC), which became the European Union (EU) in 1993.
