In 1618, the Dutch Republic was split by a religious dispute inside the Reformed Church. Remonstrants followed the ideas of Leiden theologian Jacobus Arminius, while Counter-Remonstrants followed Franciscus Gomarus. They disagreed over predestination—how God’s choice and human faith were connected—and over how much power the state should have in church affairs.
The dispute spread far beyond theology. Johan van Oldenbarnevelt, the leading statesman of Holland, supported the Remonstrants and a policy of tolerance. Prince Maurice of Orange, stadtholder and commander of the army, backed the Counter-Remonstrants. Pamphlets, rival church services and political decisions pulled cities and provinces into the conflict, and civil war threatened the Republic.
The struggle turned into a fight over political authority. On 31 July 1618, Maurice ordered city-paid troops called waardgelders to lay down their weapons in Utrecht. On 29 August, the States General, the central assembly of the seven provinces, arrested Oldenbarnevelt, Hugo Grotius and other allies. On 13 November, a national church synod opened in Dordrecht to settle the religious dispute.
The Synod of Dort rejected the Remonstrant position and set out the Counter-Remonstrant teaching in the Canons of Dort. Remonstrant ministers were removed from the Reformed Church, and the Remonstrant movement continued as its own community. The crisis also strengthened Maurice’s political position and showed how closely religion and government were linked in the young Republic. A church dispute became a national power struggle.
