The Remonstrants (or the Remonstrant Brotherhood) is a Protestant movement that split from the Dutch Reformed Church in the early 17th century. The early Remonstrants supported Jacobus Arminius, and after his death, continued to maintain his original views called Arminianism against the proponents of Calvinism. Condemned by the synod of Dort (1618–1619), the Remonstrants remained in a small minority in the Netherlands. In the middle of the 19th century, the Remonstrant Brotherhood was influenced by the liberal Dutch theological movement. Five Articles of Remonstrance In formulating Arminianism, Jacobus Arminius disagreed with Calvin, especially on predestination. He defended free examination as superior to the doctrines of established churches. In 1610, Arminius followers presented to the States of Holland and Friesland the Five Articles of Remonstrance formulating their points of disagreement with Calvinism as adopted by the Dutch Reformed Church. Supporters of Arminius were called "Remonstrants", but they were also called "Arminians". Their adversaries, inspired by Franciscus Gomarus, became known as Gomarists or Counter-Remonstrants. Although the States-General issued an edict tolerating both parties and forbidding further dispute, the conflict continued and became linked to political conflicts in the Dutch Republic. The Remonstrants were assailed both by personal enemies and by the political weapons of Maurice of Orange. Their foremost ally, Johan van Oldenbarnevelt, was executed, and other leaders were imprisoned. In Amsterdam, as in various other cities, the city government was purged of Oldenbarnevelt supporters; Jacob Dircksz de Graeff and Cornelis Hooft fell victim to this action. In 1618–1619 the Synod of Dordrecht, after expelling the thirteen Arminian pastors headed by Simon Episcopius, established the victory of the Calvinist school. It drew up ninety-three canonical rules, and confirmed the authority of the Belgic Confession and the Heidelberg Catechism.
