Jacobus Arminius, Dutch Reformed theologian (b. 1560)
Jacobus Arminius (10 October 1560 – 19 October 1609), the Latinized name of Jakob Hermanszoon, was a Dutch theologian during the Protestant Reformation period whose views became the basis of Arminianism and the Dutch Remonstrant movement. He served from 1603 as professor in theology at the University of Leiden and wrote many books and treatises on theology.
Following his death, his challenge to the Reformed standard, the Belgic Confession, provoked ample discussion at the Synod of Dort, which crafted the five points of Calvinism in response to Arminius's teaching.
