In 1559 Philip II left the Netherlands for Spain, where, from then on, he was to rule his empire. The government of the Provinces united by his father, Charles V, was left to his bastard sister Margaret, Duchess of Parma. Although she faithfully followed the Habsburg line, which in religion meant opposing Protestantism, her reign was characterized by a certain lack of firmness, enabling opposing factions to assert themselves. Shortly before Philip’s departure, Henry II, his French rival, had died in a tournament. His children and widow were as unable to quell the religious unrest in France as Margaret was in the Netherlands. In this situation, Calvinism grew irresistibly: from around 1555, it had already increased greatly in strength under Henry II, and in 1559 it had managed to hold a synod in Paris. That synod, as well as drawing up a Confession of Faith, produced its Discipline or Church Ordinance; and the best way of tracing the growth of Calvinism is to examine how rapidly the synods met, and to see how the Church Ordinances were adjusted to meet particular circumstances. That this development in the French Reformed Church had repercussions in the adjoining Netherlands, where the same language was spoken, at least in part, needs scarcely to be emphasized. Besides, during the reign of Elizabeth I, Calvinist refugee congregations were established in England, and these, in turn, could be used as bases for serving the Netherlands.
