In the history of the Dutch Republic, Orangism or prinsgezindheid ("pro-prince stance") was a political force opposing the Staatsgezinde (pro-Republic) party. Orangists supported the princes of Oranges as Stadtholders (a position held by members of the House of Orange) and military commanders of the Republic, as a check on the regents' power. The Orangist party drew its members largely from the common people, soldiers, the nobility and orthodox preachers, though its support fluctuated heavily over the course of the Republic's history.
Orangism can be seen as a continuation of the political opposition between the remonstrants and counter-remonstrants during the Twelve Years' Truce. The Remonstrants were tolerant and republican, with a liberal view on biblical interpretation, no belief in predestination and were led by men like Johan van Oldenbarnevelt. Maurice of Nassau, Prince of Orange relied on the counter-remonstrants to oppose van Oldenbarnevelt and support the prince's claim to the Dutch throne or stadthoudership, and things got so bad that civil war threatened.
Orangists such as the Vice-Admiral Johan Evertsen backed the election of William III, Prince of Orange, the posthumously-born son of William II, Prince of Orange, to the office of stadtholder of the Netherlands. The office had been vacant since the death of William II in 1650. The pro-Republic party was marked by caution (especially in all matters that could harm trade), led by raadspensionaris Johan de Witt and had supporters among the ruling class and the regenten. It was de Witt who, in the 1654 peace with England and its leader Oliver Cromwell, included the secret Act of Seclusion banning the stadtholder from leadership of the Republic. De Witt then put pressure on all seven of the Republic's provinces to uphold this ban. The pro-prince party was led by the stadholder himself and by men such as Cornelis Tromp. It played an important part in the expulsion of the de Witt brothers, which culminated in 1672 with William III's election as stadtholder on 28 June and with an organised lynch-mob at the Binnenhof on the Hague on 20 August.
