Differences between Catholic and Protestant countries did not incite rivalries between European states, or cause the growing sense of national identity and, sometimes, isolationism that was developing among the countries of Europe. These were happening anyway, for a complex variety of political and economic reasons. But religious differences did, at times, contribute to them—for example in Spain, where the inward-looking institutions of the Counter-Reformation seemed aimed at creating a nation of soldiers and ecclesiastics in great contrast to the outgoing, trade-based, profit-minded society of the Calvinist Netherlands. These generalizations hide many local variations—there were busy Spanish merchants, and contemplative, spiritual, people in many Protestant lands. But travelers across Europe remarked on the increasingly striking differences between nations.
