For the moment Holland lay crushed at the feet of Lewis, but the arrogant demands of the conqueror roused again the stubborn courage which had wrested victory from Alva and worn out the pride of Philip the Second. De Witt was murdered in a popular tumult, and his fall called William, the Prince of Orange, to the head of the Republic. The new Stadtholder had hardly reached manhood; but he had no sooner taken the lead in public affairs than his great qualities made themselves felt. His earlier life had schooled him in a wonderful self-control. He had been left fatherless and all but friendless in childhood; he had been bred among men who regarded his very existence as a danger to the State; his words had been watched, his looks noted, his friends jealously withdrawn. In such an atmosphere the boy grew up silent, wary, self-contained, grave in temper, cold in demeanour, blunt and even repulsive in address. He was weak and sickly from his cradle, and manhood brought with it an asthma and consumption which shook his frame with a constant cough; his face was sullen and bloodless, and scored with deep lines which told of ceaseless pain. But beneath this cold and sickly presence lay a fiery and commanding temper, an immovable courage, and a political ability of the highest order. William was a born statesman. Neglected as his education had been in other ways, for he knew nothing of letters or of art, he had been carefully trained in politics by John de Witt; and the wide knowledge with which in his first address to the States-General the young Stadtholder reviewed the general state of Europe, the sagacity with which he calculated the chances of the struggle, at once won him the trust of his countrymen.
