Rhodolph, his eldest son, was twenty-two years of age at the time of his father's death. Frederic II., one of the most renowned monarchs of the middle ages, was then Emperor of that conglomeration of heterogeneous States called Germany. Each of these States had its own independent ruler and laws, but they were all held together by a common bond for mutual protection, and some one illustrious sovereign was chosen as Emperor of Germany, to preside over their common affairs. The Emperor of Germany, having influence over all these States, was consequently, in position, the great man of the age.

Albert, Count of Hapsburg, had been one of the favorite captains of Frederic II. in the numerous wars which desolated Europe in that dark age. He was often at court, and the emperor even condescended to present his son Rhodolph at the font for baptism. As the child grew, he was trained to all athletic feats, riding ungovernable horses, throwing the javelin, wrestling, running, and fencing. He early gave indications of surprising mental and bodily vigor, and, at an age when most lads are considered merely children, he accompanied his father to the camp and to the court. Upon the death of his father, Rhodolph inherited the ancestral castle, and the moderate possessions of a Swiss baron. He was surrounded by barons of far greater wealth and power than himself, and his proud spirit was roused, in disregard of his father's counsels, to aggrandize his fortunes by force of arms, the only way then by which wealth and power could be attained. He exhausted his revenues by maintaining a princely establishment, organized a well-selected band of his vassals into a military corps, which he drilled to a state of perfect discipline, and then commenced a series of incursions upon his neighbors. From some feeble barons he won territory, thus extending his domains; from others he extorted money, thus enabling him to reward his troops, and to add to their number by engaging fearless spirits in his service wherever he could find them.

In the year 1245, Rhodolph strengthened himself still more by an advantageous marriage with Gertrude, the beautiful daughter of the Count of Hohenberg. With his bride he received as her dowry the castle of Oeltingen, and very considerable territorial possessions. Thus in five years Rhodolph, by that species of robbery which was then called heroic adventure, and by a fortunate marriage, had more than doubled his hereditary inheritance. The charms of his bride, and the care of his estates seem for a few years to have arrested the progress of his ambition; for we can find no further notice of him among the ancient chronicles for eight years. But, with almost all men, love is an ephemeral passion, which is eventually vanquished by other powers of the soul. Ambition slumbered for a little time, but was soon roused anew, invigorated by repose.

In 1253 we find Rhodolph heading a foray of steel-clad knights, with their banded followers, in a midnight attack upon the city of Basle. They break over all the defenses, sweep all opposition before them, and in the fury of the fight, either by accident or as a necessity of war, sacrilegiously set fire to a nunnery. For this crime Rhodolph was excommunicated by the pope. Excommunication was then no farce. There were few who dared to serve a prince upon whom the denunciations of the Church had fallen. It was a stunning blow, from which few men could recover. Rhodolph, instead of sinking in despair, endeavored, by new acts of obedience and devotion to the Church, to obtain the revocation of the sentence.

In the region now called Prussia, there was then a barbaric pagan race, against whom the pope had published a crusade. Into this war the excommunicated Rhodolph plunged with all the impetuosity of his nature; he resolved to work out absolution, by converting, with all the potency of fire and sword, the barbarians to the Church. His penitence and zeal seem to have been accepted, for we soon find him on good terms again with the pope. He now sought to have a hand in every quarrel, far and near. Wherever the sounds of war are raised, the shout of Rhodolph is heard urging to the strife. In every hot and fiery foray, the steed of Rhodolph is rearing and plunging, and his saber strokes fall in ringing blows upon cuirass and helmet. He efficiently aided the city of Strasbourg in their war against their bishop, and received from them in gratitude extensive territories, while at the same time they reared a monument to his name, portions of which still exist. His younger brother died, leaving an only daughter, Anne, with a large inheritance. Rhodolph, as her guardian, came into possession of the counties of Kyburg, Lentzburg and Baden, and other scattered domains.

This rapidly-increasing wealth and power, did but increase his energy and his spirit of encroachment. And yet he adopted principles of honor which were far from common in that age of barbaric violence. He would never stoop to ordinary robbery, or harass peasants and helpless travelers, as was constantly done by the turbulent barons around him. His warfare was against the castle, never against the cottage. He met in arms the panoplied knight, never the timid and crouching peasant. He swept the roads of the banditti by which they were infested, and often espoused the cause of citizens and freemen against the turbulent barons and haughty prelates. He thus gained a wide-spread reputation for justice, as well as for prowess, and the name of Rhodolph of Hapsburg was ascending fast into renown. Every post of authority then required the agency of a military arm. The feeble cantons would seek the protection of a powerful chief; the citizens of a wealthy town, ever liable to be robbed by bishop or baron, looked around for some warrior who had invincible troops at his command for their protection. Thus Rhodolph of Hapsburg was chosen chief of the mountaineers of Uri, Schweitz and Underwalden; and all their trained bands were ready, when his bugle note echoed through their defiles, to follow him unquestioning, and to do his bidding. The citizens of Zurich chose Rhodolph of Hapsburg as their prefect or mayor; and whenever his banner was unfurled in their streets, all the troops of the city were at his command.

The neighboring barons, alarmed at this rapid aggrandizement of Rhodolph, formed an alliance to crush him. The mountaineers heard his bugle call, and rushed to his aid. Zurich opened her gates, and her marshaled troops hastened to his banner. From Hapsburg, and Rheinfelden, and Suabia, and Brisgau, and we know not how many other of the territorial possessions of the count, the vassals rushed to the aid of their lord. They met in one of the valleys of Zurich. The battle was short, and the confederated barons were put to utter flight. Some took refuge in the strong castle of Balder, upon a rocky cliff washed by the Albis. Rhodolph selected thirty horsemen and thirty footmen.

"Will you follow me," said he, "in an enterprise where the honor will be equal to the peril?"

A universal shout of assent was the response. Concealing the footmen in a thicket, he, at the head of thirty horsemen, rode boldly to the gates of the castle, bidding defiance, with all the utterances and gesticulations of contempt, to the whole garrison. Those on the ramparts, stung by the insult, rushed out to chastise so impudent a challenge. The footmen rose from their ambush, and assailants and assailed rushed pell mell in at the open gates of the castle. The garrison were cut down or taken captive, and the fortress demolished. Another party had fled to the castle of Uttleberg. By an ingenious stratagem, this castle was also taken. Success succeeded success with such rapidity, that the confederate barons, struck with consternation, exclaimed,

"All opposition is fruitless. Rhodolph of Hapsburg is invincible."
