William married four times. His first wife was Anne of Egmont and Buren (d. 1558); in 1561 he married Anne, daughter of Elector Maurice of Saxony, in spite of the opposition of Philip II and of Anne's parents; in 1575, two years before Anne's death, he married Charlotte de Bourbon, a French princess and a runaway nun, after securing the approval of several Protestant divines; in 1583 he married Louise de Coligny, daughter of Admiral Coligny. From the first marriage Prince Philip William of Orange (d. 1616) was born; from the second and fourth marriages issued William's successors as stadtholders—Maurice of Nassau and Frederick Henry.
