district known as West Prussia, which was part of the Kingdom of Poland. However, Prussia lay outside the boundaries of the Empire, and the emperor had nothing to say about what went on there. Therefore, the elector sent notice to all the kings and princes of Europe that after this he was to be known as the “King of Prussia.” It was a situation somewhat like the one we have already referred to, when the kings of England were independent monarchs and yet subjects of the kings of France because they were also dukes of Normandy. [Illustration: Frederick The Great] The son of this elector who first called himself king had more energy and more character than his father. He ruled his country with a rod of iron, and built up a strong, well-drilled army. He was especially fond of tall soldiers, and had agents out all over Europe, kidnapping men who were over six feet tall to serve in his famous regiment of Guards. He further increased the size of the Prussian kingdom. His son was the famous Frederick the Great, one of the most remarkable fighters that the world has ever seen. This prince had been brought up under strict discipline by his father. The old king had been insistent that his son should be no weakling. It is told that one day, finding Frederick playing upon a flute, he seized the instrument and snapped it in twain over his son’s shoulder. The young Frederick, under this harsh training, became a fit leader of a military nation. When his father died and left him a well-filled treasury and a wonderfully drilled army, he was fired with the ambition to spread his kingdom wider. Germany, as has been said, was made up of a great many little counties, each ruled by its petty prince or duke, all owing homage, in a general way, to the ruler of Austria, who still was supposed to be the head of the Holy Roman Empire.
