Roman/Red
Roman/red (Dutch: Rooms/rood) is the nickname of coalitions of Catholic and social-democratic parties in the Netherlands and Belgium. Roman refers to Roman Catholic and red to the colour of social democrats. Between 1946 and 1958, the Catholic People's Party (KVP) and the social-democratic Labour Party (PvdA) formed the core of several 'Roman/red' cabinets, led by Willem Drees.
After the Catholic KVP merged with two Protestant parties to form the non-denominational Christian Democratic Appeal (CDA) in 1980, the term was used less in Dutch politics. In Belgian politics the term is still used to describe cabinets made up out of the Catholic Christian Democratic & Flemish party (CD&V) and Humanist Democratic Centre (CDh) and the social-democratic Socialist Party Different (SP.A) and Socialist Party (PS).
