The Catholic People's Party (, KVP) was a Catholic Christian democratic political party in the Netherlands. The party was founded in 1945 as a continuation of the interwar Roman Catholic State Party, which was in turn a successor of the General League of Roman Catholic Electoral Associations. The party was in government throughout its existence. In 1977, a federation of parties including the Catholic People's Party, the Anti-Revolutionary Party (ARP) and the Christian Historical Union (CHU) ran together under the Christian Democratic Appeal (CDA) banner. The three participating parties formally dissolved to form the CDA in 1980.

History 1945–1965 The KVP was founded on 22 December 1945. It was a continuation of the pre-war Roman Catholic State Party (RKSP). Unlike the RKSP, the KVP was open to people of all denominations, but mainly Catholics supported the party. The party adopted a more progressive course and a more modern image than its predecessor.

In the 1946 general election, the party won a third of the vote, and joined the newly founded social democratic Labour Party (PvdA) to form a government coalition. This Roman/Red coalition ("Roman" for the KVP, "Red" for the PvdA) lasted until 1958. In the first two years, the KVP's Louis Beel led the Cabinet. Beel was not the party's leader, a post which was taken by Carl Romme, who led the KVP from the House of Representatives between 1946 and 1961. After the 1948 general election, the PvdA supplied the prime minister Willem Drees. The PvdA and the KVP were joined by combinations of the Protestant-Christian Anti-Revolutionary Party (ARP) and Christian Historical Union (CHU) and the liberal People's Party for Freedom and Democracy (VVD) to form oversized cabinets, which often held a comfortable two-thirds majority in the House of Representatives. The cabinets were oriented at rebuilding Dutch society and economy after the ravages of World War II and grant independence to Indonesia. That last point caused a split within the KVP; in 1948, a small group of Catholics opposed to decolonisation and cooperation with social democrats broke away to form the Catholic National Party (KNP). Under pressure of the Catholic Church, the two parties reunited in 1955.

The KVP was at the height of its power from 1958 to 1965. It was the dominant force in all cabinets, and every prime minister during this time was a party member. In 1958 the fourth Drees cabinet fell and Louis Beel formed an interim cabinet with KVP, ARP and CHU. After the 1959 general election, the KVP formed a centre-right cabinet with ARP, CHU and VVD, led by KVP member Jan de Quay. It continued to strengthen the welfare state. After the 1963 general election, this cabinet was succeeded by a new cabinet of KVP-CHU-ARP-VVD, which was led by the KVP's Victor Marijnen. This coalition oversaw an economic boom. Norbert Schmelzer became the party's new leader, again operating within the House of Representatives and not the cabinet. A cabinet crisis over the Netherlands Public Broadcasting, however, caused the cabinet to fall in 1965. The KVP and ARP formed a cabinet with the PvdA, led by the KVP's Jo Cals. This cabinet also fell in the Night of Schmelzer, in which Norbert Schmelzer forced a cabinet crisis over the cabinet's financial policy. This was the first fall of cabinet directly broadcast on television. An interim government of KVP and ARP was formed, led by the ARP's Jelle Zijlstra.

1965–1980 The period 1965–1980 was period of decline, crisis and dissent for the KVP. The party's vote share began to decline after 1966 as a result of depillarisation and secularisation; there were fewer Catholics, and Catholics no longer necessarily supported a Catholic party.

In the 1967 general election, the KVP lost 15% of its votes and eight seats. During the election campaign the KVP, ARP and CHU declared that they wanted to continue cooperating with each other. Cooperation with the PvdA was much less important. This led to unrest among young and left-wing KVP supporters, including Ruud Lubbers, Jo Cals, Erik Jurgens and Jacques Aarden, who called themselves Christian Radicals. After the election, this promise was upheld and the KVP formed a cabinet with its old partners, led by Piet de Jong. After much debate, some of the Christian Radicals broke away from the KVP in 1968 to form the Political Party of Radicals (PPR). These include three members of parliament, who form their own parliamentary party, Groep Aarden. Lubbers and Cals stayed with the KVP. The new party became a close partner of the PvdA. In the 1971 general election, the KVP lost another seven seats (18% of its vote). The KVP again joined the ARP, CHU and VVD to form a new centre-right cabinet with right-wing dissenters of the PvdA, united in Democratic Socialists '70 (DS'70). The ARP's Barend Biesheuvel led the cabinet. In 1972 the cabinet fell because of internal problems of the junior partner, DS'70.

In the subsequent election, the KVP again lost eight seats, leaving only 27, 23 less than in 1963. The cabinet lost its majority and the KVP saw no alternative than to cooperate with the PvdA and its allies PPR and Democrats 66 (D'66). An extra-parliamentary cabinet was formed by PvdA, PPR and D66 joined by prominent progressives from KVP and ARP. The KVP's ministers include the minister of Justice Dries van Agt and the minister of the Economy Ruud Lubbers. The KVP did not officially support this cabinet, which was led by social democrat Joop den Uyl. This cabinet was characterised by infighting and fell just before the 1977 general election.

In the 1970s, the KVP realised that if it was to continue, it needed to find new ways of cooperating. Ideas to form a broad Christian democratic party, like the German Christian Democratic Union, were brought into practice. In 1974 the three parties formed a federation, called Christian Democratic Appeal (CDA). In the 1977 election the CDA won more seats than the KVP, ARP and CHU had together. After the election, Dries van Agt became prime minister. In 1980, the three parties officially dissolved themselves into the CDA.

The Catholics still constitute a powerful group within the CDA. Indeed, the CDA's first two prime ministers, van Agt and Ruud Lubbers, came from the KVP side of the merger. In the early years, a system of equal representation of Catholics and Protestants was practiced, from which the KVP as the only Catholic group profited. Nowadays many CDA members, like Maxime Verhagen and Maria van der Hoeven have a background in the KVP's political Catholicism.

Name The name Catholic People's Party (Dutch: Katholieke Volkspartij; KVP), must be seen in contrast with the name of its predecessor Roman Catholic State Party. The party no longer uses the name "Roman Catholic", but simply "Catholic", de-emphasising its religious affiliation. It is no longer a state party, but a people's party, emphasising its progressive, democratic nature. The new name emphasises the KVP's progressive, democratic and non-denominational image.

Ideology

The KVP was a Christian democratic party, which based itself on the Bible and Catholic dogma.

As such, it was a proponent of a mixed economy: A strong welfare state should be combined with a free market, with a corporatist organisation. Trade unions and employers' organisations were to negotiate on wages in a Social and Economic Council and should make legislation for some economic sectors on themselves, without government intervention, in so-called Productschappen. It was also described as conservative liberal party.

The state should watch over the morality of the people: divorce should be limited, recreation should be moral (for instance different swimming hours for women and men) and the family should be preserved. Families were to be helped by fiscal policies, such as the kinderbijslag, support by the government, by the newly set up Ministry of Culture, Recreation and Welfare, and the possibility to buy their own home.

Internationally, the KVP was a staunch proponent of European integration and cooperation within NATO. The party sought the middle ground in the issue of decolonisation: Indonesia and Suriname should be independent countries within a Dutch Commonwealth.

The party was particularly strong in the southern provinces of Limburg and North Brabant, where it often held 90% of the seats in the provincial and municipal legislatures and supplied all provincial and municipal governments, provincial governors and mayors. In regions like Twente, West Friesland and Zeelandic Flanders it held similar positions in municipalities, but cooperated with other parties on the provincial level.
