 The best known example is the new Spanish Netherlands (essentially modern Belgium), which had been the centre of Protestantism in the Netherlands but became (initially) exclusively Catholic after the Spanish drove the Protestants to the north, where they established the United Provinces.Rubens was one of a number of Flemish Baroque painters who received many commissions, and produced several of his best known works re-filling the empty churches.Several cities in France in the French wars of religion and in Germany, Bohemia and elsewhere in the Thirty Years War saw similar bursts of restocking.
