Deep in the heart of Germany lay the earldom of Nassau. The Dillenburg was the count's castle. With its towers and gardens surrounded by thick strong walls, it sat high on the mountainside, its mighty drawbridge spanning the tumultuous Dille River. In the midst of this setting was born William of Nassau (1533-1584), who was only 11 years old when he inherited the principality of Orange. This biography written for children tells about the life of one of the greatest heroes of the Protestants.
