Maurice, Prince of Orange disbands the waardgelders militia in Utrecht, a pivotal event in the Remonstrant/Counter-Remonstrant tensions.

Maurice of Orange was stadtholder of all the provinces of the Dutch Republic—except Friesland—from 1585 until his death. Prior to inheriting the title Prince of Orange from his elder half-brother, Philip William, in 1618, he was known as Maurice of Nassau.

Utrecht is the fourth-largest city of the Netherlands, as well as the capital and the most populous city of the province of Utrecht. The municipality of Utrecht is located in the eastern part of the Randstad conurbation, in the very centre of mainland Netherlands, and includes Haarzuilens, Vleuten and De Meern. It has a population of 376,435 as of January 2025.

The Remonstrants 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 a small minority in the Netherlands. In the middle of the 19th century, the Remonstrant Brotherhood was influenced by the liberal Dutch theological movement.

Franciscus Gomarus was a Dutch theologian, a strict Calvinist and an opponent of the teaching of Jacobus Arminius, whose theological disputes were addressed at the Synod of Dort (1618–19).
