The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1648]
governors, who, for the most part, were soldiers of fortune, seduced their mercenary legions, assumed the Imperial purple, and either failed or succeeded in their revolt, without wounding the power and unity of government. If the dukes, margraves, and counts of Germany, were less audacious in their claims, the consequences of their success were more lasting and pernicious to the state. Instead of aiming at the supreme rank, they silently labored to establish and appropriate their provincial independence. Their ambition was seconded by the weight of their estates and vassals, their mutual example and support, the common interest of the subordinate nobility, the change of princes and families, the minorities of Otho the Third and Henry the Fourth, the ambition of the popes, and the vain pursuit of the fugitive crowns of Italy and Rome. All the attributes of regal and territorial jurisdiction were gradually usurped by the commanders of the provinces; the right of peace and war, of life and death, of coinage and taxation, of foreign alliance and domestic economy. Whatever had been seized by violence, was ratified by favor or distress, was granted as the price of a doubtful vote or a voluntary service; whatever had been granted to one could not, without injury, be denied to his successor or equal; and every act of local or temporary possession was insensibly moulded into the constitution of the Germanic kingdom. In every province, the visible presence of the duke or count was interposed between the throne and the nobles; the subjects of the law became the vassals of a private chief; and the standard which he received from his sovereign, was often raised against him in the field. The temporal power of the clergy was cherished and exalted by the superstition or policy of the Carlovingian and Saxon dynasties, who blindly depended on their moderation and fidelity; and the bishoprics of Germany were made equal in extent and privilege, superior in wealth and population, to the most ample states of the military order. As long as the emperors retained the prerogative of bestowing on every vacancy these ecclesiastic and secular benefices, their cause was maintained by the gratitude or ambition of their friends and favorites. But in the quarrel of the investitures, they were deprived of their influence over the episcopal chapters; the freedom of election was restored, and the sovereign was reduced, by a solemn mockery, to his first prayers, the recommendation, once in his reign, to a single prebend in each church. The secular governors, instead of being recalled at the will of a superior, could be degraded only by the sentence of their peers. In the first age of the monarchy, the appointment of the son to the duchy or county of his father, was solicited as a favor; it was gradually obtained as a custom, and extorted as a right: the lineal succession was often extended to the collateral or female branches; the states of the empire (their popular, and at length their legal, appellation) were divided and alienated by testament and sale; and all idea of a public trust was lost in that of a private and perpetual inheritance. The emperor could not even be enriched by the casualties of forfeiture and extinction: within the term of a year, he was obliged to dispose of the vacant fief; and, in the choice of the candidate, it was his duty to consult either the general or the provincial diet.
After the death of Frederic the Second, Germany was left a monster with a hundred heads. A crowd of princes and prelates disputed the ruins of the empire: the lords of innumerable castles were less prone to obey, than to imitate, their superiors; and, according to the measure of their strength, their incessant hostilities received the names of conquest or robbery. Such anarchy was the inevitable consequence of the laws and manners of Europe; and the kingdoms of France and Italy were shivered into fragments by the violence of the same tempest. But the Italian cities and the French vassals were divided and destroyed, while the union of the Germans has produced,
