Beyond the frontiers of the fading Empire lay that outer land, as loose and drifting as a sea, which had boiled over in the barbarian wars. Most of it was now formally Christian, but barely civilized; a faint awe of the culture of the south and west lay on its wild forces like a light frost. This semi-civilized world had long been asleep; but it had begun to dream. In the generation before Elizabeth a great man who, with all his violence, was vitally a dreamer, Martin Luther, had cried out in his sleep in a voice like thunder, partly against the place of bad customs, but largely also against the place of good works in the Christian scheme. In the generation after Elizabeth the spread of the new wild doctrines in the old wild lands had sucked Central Europe into a cyclic war of creeds. In this the house which stood for the legend of the Holy Roman Empire, Austria, the Germanic partner of Spain, fought for the old religion against a league of other Germans fighting for the new. The continental conditions were indeed complicated, and grew more and more complicated as the dream of restoring religious unity receded. They were complicated by the firm determination of France to be a nation in the full modern sense; to stand free and foursquare from all combinations; a purpose which led her, while hating her own Protestants at home, to give diplomatic support to many Protestants abroad, simply because it preserved the balance of power against the gigantic confederation of Spaniards and Austrians. It is complicated by the rise of a Calvinistic and commercial power in the Netherlands, logical, defiant, defending its own independence valiantly against Spain. But on the whole we shall be right if we see the first throes of the modern international problems in what is called the Thirty Years' War; whether we call it the revolt of half-heathens against the Holy Roman Empire, or whether we call it the coming of new sciences, new philosophies, and new ethics from the north. Sweden took a hand in the struggle, and sent a military hero to the help of the newer Germany. But the sort of military heroism everywhere exhibited offered a strange combination of more and more complex strategic science with the most naked and cannibal cruelty. Other forces besides Sweden found a career in the carnage. Far away to the north-east, in a sterile land of fens, a small ambitious family of money-lenders who had become squires, vigilant, thrifty, thoroughly selfish, rather thinly adopted the theories of Luther, and began to lend their almost savage hinds as soldiers on the Protestant side. They were well paid for it by step after step of promotion; but at this time their principality was only the old Mark of Brandenburg. Their own name was Hohenzollern. XIII THE AGE OF THE PURITANS
