Formation, 1944-1946 After the
Liberation of Belgium from German occupation in September 1944, there was little support for resurrecting the pre-war Catholic Party. Martin Conway writes that "although all were agreed on the need to avoid a return to the Catholic Party of the inter-war years, Belgian Catholics emerged from the war with a renewed sense of their common purpose and a heightened optimism that the values of Catholicism did indeed offer a distinctive solution to the problems of a modern democratic society". The Christian Social Party was formally established on 19 August 1945 under the presidency of
August De Schryver. The new party's ideology drew heavily from
personalism and sought to demonstrate its distance from the institutional
Catholic Church by dropping the word "Catholic" in favour of the less
sectarian term "Christian". Participating in the
first post-war elections in February 1946, it won nearly 43% of the national vote exceeding the total vote share gained by the Catholic Party at any previous elections since World War I. A separate new party attempting to attract left-leaning Christian Democratic voters called the
Belgian Democratic Union (
Union démocratique belge/
Belgische Democratische Unie) failed to make an electoral breakthrough at the elections and was soon disbanded. The same elections also saw the re-emergence of liberal and
socialist parties which, alongside the Christian Social Party, would dominate Belgian politics over the following two decades.
Christian Social Party in government, 1946-1954 and 1958-1968 In contrast to the conservatism of the Catholic Party, the Christian Social Party (
Parti social chrétien/
Christelijke Volkspartij) stood on a democratic platform emphasising social reforms, welfare,
industrial democracy, and moderate economic redistribution. It rallied to the monarchist cause during the
Royal Question (1949-50) and supported
King Leopold III's return to the throne. Standing on this issue, the party won the last bicameral majority in Belgian history in the
1950 general election. Although ultimately successful, Leopold's return proved politically divisive and caused widespread unrest in industrial regions of
Wallonia. Seeking to de-escalate the crisis at its peak in Summer 1950, Leopold agreed to abdicate in favour of his son
Prince Baudouin the following year. Leopold's abdication caused considerable agitation within the party and it was ultimately forced out of power in 1954. In opposition, the party was revitalised in opposition to the
Second School War (1954-58) initiated by the Liberal and Socialist parties which challenged the Church's continuing influence within the Belgian education system. It was eventually ended with a compromise in the form of the "School Pact" and the return of the Christian Social Party to government in the
1958 elections. As a result of the economic fall-out from the independence of the
Belgian Congo, the government of
Gaston Eyskens introduced an austerity plan known as the
Unitary Law in 1960. Opposition to the programme led to the
1960-61 general strike but failed to prevent its passage. Alongside increasing
secularism within Belgian society and growing demands for
federalising reforms in both Wallonia and Flanders, the dominance of the Christian Social Party finally came into question in late 1960s.
Linguistic split, 1968-1972 As part of the unrest leading to the
split of the Catholic University of Leuven, the government of
Paul Vanden Boeynants refused to intervene to remove Francophone students from the university in accordance with the demands of Flemish student demonstrators. In response, Flemish ministers to withdraw from the government in February 1968. The regionalist
Volksunie made significant inroads into the Christian Democratic vote in Flanders. In the
March 1968 general election, the regional Flemish (
Christelijke Volkspartij) and Walloon (
Parti Social Chrétien) parties stood on different programmes but continued to retain a single national president until 1972. They subsequently stood as entirely separate parties with different programmes and political identities, marking the collapse of the "unitary" Christian Social Party. ==Election results==
