From 1829 to 1833 he acted as secretary to William II of the Netherlands in Brussels. Afterwards he took a prominent part in Dutch domestic politics, and gradually became the leader of the Anti-Revolutionary Party,
Groen was ardently opposed to constitutionalist Thorbecke, the father of Dutch parliamentarism, whose principles he denounced as ungodly and revolutionary. Although Groen lived to see these principles triumph in the constitutional reforms implemented by Thorbecke, he never ceased to oppose them until his death in 1876.
