Portrait of Frederick Henry of Nassau (1584-1647), Prince of Orange and stadtholder of Holland, Zeeland, Utrecht, Guelders, Overijssel in the Dutch Republic (1625-1647), 1629
Frederick Henry (Dutch: Frederik Hendrik van Oranje; 29 January 1584 – 14 March 1647) was the sovereign prince of Orange and stadtholder of Holland, Zeeland, Utrecht, Guelders, Overijssel in the Dutch Republic from 1625 until his death in 1647. The last seven years of his life he also was the stadtholder of Groningen (1640-1647). As the leading soldier in the Dutch wars against Spain, his main achievement was the successful Siege of 's-Hertogenbosch in 1629. It was the main Spanish base and a well-fortified city protected by an experienced Spanish garrison and by formidable water defenses. His strategy was the successful neutralization of the threat of inundation of the area around 's-Hertogenbosch and his capture of the Spanish storehouse at Wesel. Frederick Henry was born on 29 January 1584 in Delft, Holland, Dutch Republic. He was the youngest child of William the Silent and Louise de Coligny. His father William was stadtholder of Holland, Zeeland, Utrecht, and Friesland. His mother Louise was daughter of the Huguenot leader Gaspard de Coligny, and was the fourth wife of his father. He was thus the half brother of his predecessor Maurice of Orange, deceased in 1625. Frederick Henry was born six months before his father's assassination on 10 July 1584. The boy was trained to arms by his elder brother Maurice, one of the finest generals of his age. After Maurice threatened to legitimize his illegitimate children if he did not marry, Frederick Henry married Amalia of Solms-Braunfels in 1625. On the death of Maurice in 1625 without legitimate issue, Frederick Henry succeeded him in his paternal dignities and estates, and also in the stadtholderates of the five provinces of Holland, Zeeland, Utrecht, Overijssel and Guelders, and in the important posts of captain and admiral-general of the Union (commander-in-chief of the Dutch States Army and of the Dutch navy). Frederick Henry proved himself almost as good a general as his brother, and a far more capable statesman and politician. For twenty-two years he remained at the head of government in the United Provinces, and in his time the power of the stadtholderate reached its highest point. The "Period of Frederick Henry," as it is usually styled by Dutch writers, is generally accounted the golden age of the republic. It was marked by great military and naval triumphs, by worldwide maritime and commercial expansion, and by a wonderful outburst of activity in the domains of art and literature.
