The dream of bliss became a nightmare. As the tide of Protestantism ebbed and flowed in various parts of the Holy Roman Empire, so the fortunes of the Brethren ebbed and flowed in the old home of their fathers. We have seen how the Brethren rose to prosperity and power. We have now to see what brought about their ruin. It was nothing in the moral character of the Brethren themselves. It was purely and simply their geographical position. If Bohemia had only been an island, as Shakespeare seems to have thought it was, it is more than likely that the Church of the Brethren would have flourished there down to the present day. But Bohemia lay in the very heart of European politics; the King was always a member of the House of Austria; the House of Austria was the champion of the Catholic faith, and the Brethren now were crushed to powder in the midst of that mighty European conflict known as the Thirty Years' War. We note briefly the main stages of the process. The first cause was the rising power of the Jesuits. For the last fifty years these zealous men had been quietly extending their influence in the country. They had built a magnificent college in Prague. They had established a number of schools for the common people. They had obtained positions as tutors in noble families. They went about from village to village, preaching, sometimes in the village churches and sometimes in the open air; and one of their number, Wenzel Sturm, had written an exhaustive treatise denouncing the doctrines of the Brethren. But now these Jesuits used more violent measures. They attacked the Brethren in hot, abusive language. They declared that the wives of Protestant ministers were whores. They denounced their children as bastards. They declared that it was better to have the devil in the house than a Protestant woman. And the more they preached, and the more they wrote, the keener the party feeling in Bohemia grew.
