At the same time he was being tutored in law by Savigny and in finance by a series of distinguished masters. In 1823 he married the princess Elizabeth of Bavaria, who adopted the Lutheran creed. The union, though childless, was very happy. A long tour in Italy in 1828 was the beginning of his intimacy with Bunsen and did much to develop his knowledge of art and love of antiquity. On his accession to the throne in 1840 much was expected of a prince so variously gifted and of so amiable a temper, and his first acts did not belie popular hopes. He reversed the unfortunate ecclesiastical policy of his father, allowing a wide liberty of dissent, and releasing the imprisoned archbishop of Cologne; he modified the strictness of the press censorship; above all he undertook, in the presence of the deputations of the provincial diets assembled to greet him on his accession, to carry out the long-deferred project of creating a central constitution, which he admitted to be required alike by the royal promises, the needs of the country and the temper of the times. The story of the evolution of the Prussian parliament belongs to the history of Prussia. Here it must suffice to notice Frederick William's personal share in the question, which was determined by his general attitude of mind. He was an idealist; but his idealism was of a type the exact reverse of that which the Revolution in arms had sought to impose upon Europe. The idea of the sovereignty of the people was to him utterly abhorrent, and even any delegation of sovereign power on his own part would have seemed a betrayal of a God-given trust. "I will never," he declared, "allow to come between Almighty God and this country a blotted parchment, to rule us with paragraphs, and to replace the ancient, sacred bond of loyalty." His vision of the ideal state was that of a patriarchial monarchy, surrounded and advised by the traditional estates of the realm--nobles, peasants, burghers--and cemented by the bonds of evangelical religion; but in which there should be no question of the sovereign power being vested in any other hands than those of the king by divine right. In Prussia, with its traditional loyalty and its old-world caste divisions, he believed that such a conception could be realized, and he took up an attitude half-way between those who would have rejected the proposal for a central diet altogether as a dangerous "thin end of the wedge," and those who would have approximated it more to the modern conception of a parliament. With a charter, or a representative system based on population, he would have nothing to do. The united diet which was opened on the 3rd of February 1847 was no more than a congregation of the diets instituted by Frederick William III. in the eight provinces of Prussia. Unrepresentative though it was--for the industrial working-classes had no share in it--it at once gave voice to the demand for a constitutional system.
