election in which the party lost one seat, the De Quay cabinet is formed by KVP, ARP, CHU and VVD. The CHU still supplied two ministers. After the 1963 elections, in which the CHU gained one seat, the cabinet continued. In 1965 this cabinet fell, and a new cabinet was formed, without the CHU and the VVD, but with the PvdA. This cabinet fell after one year. In the 1967 election campaign the ARP, CHU and KVP declare that will continue to govern together. The CHU lost one seat but still supplied two ministers in the new KVP-ARP-CHU-VVD coalition De Jong cabinet. During this period the differences between the ARP and CHU became more pronounced, with the ARP becoming more progressive and the CHU remaining more conservative. In the 1971 election the party's leader Udink made a fool out of himself by posing as a hippie: the party lost three seats. It joined a coalition cabinet of the same parties, now joined by the moderate Democratic Socialists '70, which broke away from the PvdA. The cabinet fell after one year. In the 1972 election campaign the CHU lost three seats, and was left with seven. Furthermore, CHU was blocked from the newly formed cabinet by the PvdA and its allies, which cooperated with the KVP and ARP. Meanwhile, a process of merger had started between the KVP, ARP and CHU, under pressure of poor election results. In 1974 they found a federation called the Christian Democratic Appeal (CDA). In the 1977 election they campaigned together under the name of the CDA. The power of the CHU current within the CDA is relatively small. Although there are some prominent CDA politicians with a background in the CHU, the better organised KVP and ARP are far stronger currents within the party. Name The CHU derived its name "Christian Historical Union" from its combination of conservatism, the orientation to that which has historically grown with Protestant Christianity. The label conservative was already taken by a parliamentary group of monarchists and colonialists, who fell from favour during the late 19th century. In its early years the terms anti-revolutionary and Christian-historical were used interchangeable. With the split between the Anti-Revolutionary Party and the CHU the terms began to gain their own separate meanings. Furthermore, the party styled itself a loose union of individual MPs and municipal caucuses and therefore used the term Union instead of
