The Free University of Brussels, founded in 1834, split along linguistic lines in 1969, creating the Université libre de Bruxelles (ULB) and Vrije Universiteit Brussel (VUB). In politics, the Leuven affair revealed a split between French- and Dutch-speaking factions within the Christian Social Party, especially in the 1968 elections where both factions had campaigned on different manifestos. The split was formalised in 1972 when the old party split along linguistic lines into the Parti social chrétien and Christelijke Volkspartij.
