In the first years of the Republic, controversy arose within the Reformed Church, mainly around the subject of predestination. This has become known as the struggle between Arminianism and Gomarism, or between Remonstrants and Contra-Remonstrants. In 1618 the Synod of Dort tackled this issue, which led to the banning of the Remonstrant faith.
