text: In the 1905 election, the ARP lost only 3% of the vote, but eight seats, although it was able to strengthen its position in the Senate. Kuyper, the party's leader, lost his own seat in Amsterdam to a progressive liberal. Theo Heemskerk led the anti-revolutionary parliamentary party. A minority liberal cabinet was formed. Former anti-revolutionary MP Staalman left ARP and founded the Christian Democratic Party, which later became the Christian Democratic Union, which would play a minor role in the interbellum political landscape.
  In 1908, Kuyper returned to the House of Representatives. After a crisis in the liberal cabinet Theo Heemskerk was given the chance to form a new cabinet. A minority confessional cabinet was formed. In the 1909 election the ARP won 3% of vote and twenty-five seats. The Heemskerk cabinet continues.
  In 1912, Kuyper left national politics because of health reasons, and in 1913, he was elected to the Senate. In the 1913 election, the ARP lost 6% of the votes. The party lost more than half of its seats, leaving them with 11 seats overall. Another minority liberal cabinet was formed. The leadership of the ARP lay in the hands of less prominent politicians. Although a relatively small opposition party, the ARP played an important role in Dutch politics. The liberal minority cabinet, led by Cort van der Linden sought to resolve two important issues in Dutch politics: the conflict over the equalisation of payment for religious schools and universal suffrage. In the constitution change of 1917 both items were resolved. The ARP was given equal payment for religious schools, but it had to accept women's suffrage and proportional representation.
