Upon the north-western edge of the narrow peninsula of North Holland, washed by the stormy waters of the German Ocean, were the ancient castle, town, and lordship, whence Egmont derived his family name, and the title by which he was most familiarly known. He was supposed to trace his descent, through a line of chivalrous champions and crusaders, up to the pagan kings of the most ancient of existing Teutonic races. The eighth century names of the Frisian Radbold and Adgild among his ancestors were thought to denote the antiquity of a house whose lustre had been increased in later times by the splendor of its alliances. His father, united to Francoise de Luxemburg, Princess of Gavere, had acquired by this marriage, and transmitted to his posterity, many of the proudest titles and richest estates of Flanders. Of the three children who survived him, the only daughter was afterwards united to the Count of Vaudemont, and became mother of Louise de Vaudemont, queen of the French monarch, Henry the Third.
Of his two sons, Charles, the elder, had died young and unmarried, leaving all the estates and titles of the family to his brother. Lamoral, born in 1522, was in early youth a page of the Emperor. When old enough to bear arms he demanded and obtained permission to follow the career of his adventurous sovereign. He served his apprenticeship as a soldier in the stormy expedition to Barbary, where, in his nineteenth year, he commanded a troop of light horse, and distinguished himself under the Emperor’s eye for his courage and devotion, doing the duty not only of a gallant commander but of a hardy soldier. Returning, unscathed by the war, flood, or tempest of that memorable enterprise, he reached his country by the way of Corsica, Genoa, and Lorraine, and was three years afterwards united (in the year 1545) to Sabina of Bavaria, sister of Frederick, Elector Palatine. The nuptials had taken place at Spiers, and few royal weddings could have been more brilliant. The Emperor, his brother Ferdinand King of the Romans, with the Archduke Maximilian, all the imperial electors, and a concourse of the principal nobles of the empire, were present on the occasion been at the Emperor’s side during the unlucky siege of Metz; in 1554 he had been sent at the head of a splendid embassy to England, to solicit for Philip the hand of Mary Tudor, and had witnessed the marriage in Winchester Cathedral, the same year. Although one branch of his house had, in past times, arrived at the sovereignty of Gueldres, and another had acquired the great estates and titles of Buren, which had recently passed, by intermarriage with the heiress, into the possession of the Prince of Orange, yet the Prince of Gavere, Count of Egmont, was the chief of a race which yielded to none of the great Batavian or Flemish families in antiquity, wealth, or power. Personally, he was distinguished for his bravery, and although he was not yet the idol of the camp, which he was destined
