The Christian Democratic Appeal (Dutch: Christen-Democratisch Appèl, pronounced [krɪstə(n)deːmoːkraːtis ɑˈpɛl]; CDA) is a Christian-democraticpolitical party in the Netherlands. The CDA was originally formed in 1977 from a confederation of the Catholic People's Party, the Anti-Revolutionary Party and the Christian Historical Union, and has participated in all but three Dutch governments since then. Sybrand van Haersma Buma has been the party leader since 18 May 2012.
The party suffered severe losses in the 2010 general election, losing half of its seats and falling to fourth place in the House of Representatives. From 2010 to 2012 consequently, the CDA was a junior coalition partner in a right-wing minority cabinet with the People's Party for Freedom and Democracy (VVD), supported in parliament by the Party for Freedom (PVV). Subsequently, the CDA again lost a considerable number of seats in the 2012 general election, dropping to fifth place.
Since 1880 the sizeable Catholic and Protestant parties had worked together in the so-called Coalitie. They shared a common interest in public funding of religious schools. In 1888 they formed the first Christian-democratic government, led by the Anti-Revolutionary Æneas Baron Mackay. The cooperation was not without problems and in 1894 the more anti-papist and aristocratic conservatives left the Protestant Anti Revolutionary Party, to found the Christian Historical Union (CHU). The main issues dividing Protestants and Catholics was the position of the Dutch Representation at the Holy See and the future of the Dutch Indies.
