Henry the Fowler was also called Henry "the City Builder." After the death of the last of the Charlemagne line of rulers, the Franks elected Conrad, Duke of Franconia, to succeed to the throne, and he on his death-bed advised his people to choose Henry of Saxony to succeed, for the times were stormy and the country needed a strong ruler. The Hungarians in the southeast, and the Wends, the old Slavonic population of Poland, were pillaging and harrying more and more successfully, and the more successfully the more impudently. Henry began the building of strong-walled, deep-moated cities along his frontier, and made one, drawn by lot, out of every ten families of the countryside, go to live in these fortified towns. Their rulers were burgraves, or city counts. Titles now so largely ornamental were then descriptive of duties and responsibilities. In the light of their future greatness, it is well to take note of these two frontier counties, or marches. The first, called the Northern March, or March of Brandenburg, was the religious centre of the Slays, and was situated in the midst of forests and marshes just beyond the Elbe. This March of Brandenburg was won from the Slays in the first instance by the Saxons and Franks of the Saxon plain. When the burgrave, Frederick of Hohenzollern, came to take possession of his new territory he was received with the jesting remark: "Were it to rain burgraves for a whole year, we should not allow them to grow in the march." But Frederick's soldiers and money, and his Nuremberg jewels, as his cannon were called, ended by gaining complete control, a control in more powerful hands to-day than ever before. The second, called the Eastern or Austrian March, was situated in the basin of the Danube. These two great states were formed in lands that had ceased to be German and had become Slav or Finnish territory. The fighting appetite of the German tribes, and the spirit of chivalry later, which had drawn men in other days in France to the East, in Spain against the Moors, in Normandy against England, were offered an opportunity and an outlet in Germany, by forays and fighting against the Finns and Slays. Out of the conquest and settlement of these territories grew, what we know to-day, as the German Empire and the Austrian Empire. Out of their margraves, who were at first sentinel officers guarding the outer boundaries of the empire, and mere nominees of the Emperor, have developed the Emperor of Germany and the Emperor of Austria, the one ruling over the most powerful nation, the other the head of the most exclusive court, in Europe.
