Change

The International Center Democratic Party was founded in 1961 under the name of World Union of Christian Democrats (WUCD). It was created by the New International Teams, predecessor organization to the European Union of Christian Democrats (EUCD), the Christian Democrat Organization of America (CDOA) and the Christian Democratic Union of Central Europe (CDUCE). In 1999 it adopted its present name, Centrist Democrat International.
