UNIAPAC was born in 1931 as “Conférences Internationales des Associations de Patrons Catholiques", between federations of Dutch, Belgian and French Catholic Employers (and with observers from Italy, Germany and Czechoslovakia), on the occasion of the 40 th anniversary of the Encyclical “Rerum Novarum” in Rome. After World War II, UNIAPAC enlarged to other European countries and to Latin-American Countries and changed its first name for, in French, ‘ UNion Internationale des Associations PAtronales Catholiques', with the initials UNIAPAC ( 1949 ). In 1962 , UNIAPAC becomes an ecumenical association under the new denomination "International Christian Union of Business Executives" , conserving its initials. By the same time, UNIAPAC gains members in Asia and in Africa.
Today , UNIAPAC welcomes member associations and individual members or companies from worldwide (with a larger presence in Europe and Latin-America).
