Among other reforms he changed the calendar, making the year to begin with January, and abolished the old laws with reference to marriage, by which young people had no power of choice; but he decreed that no marriage should take place unless an intimacy had existed between the parties for at least six months. He instituted balls and assemblies, to soften the manners of the people. He encouraged the theatre, protected science, invited eminent men to settle in Russia, improved the courts of justice, established posts and post-offices, boards of trade, a vigorous police, hospitals, and alms-houses. He imported Saxony sheep, erected linen, woollen, and paper mills, dug canals, suppressed gambling, and fostered industry and art. He aimed to do for Russia what Richelieu and Colbert did for France. The greatest opposition to his reforms came from the clergy, with the Patriarch at their head,--a personage of great dignity and power, ruling an _imperium in imperio_. Peter had no hostility to the Greek religion, nor to the clergy. Like Charlemagne, he was himself descended from an ecclesiastical family. But finding the clergy hostile to civil and social reforms, he sought to change the organization of the Church itself. He did not interfere with doctrines, nor discipline, nor rites, nor forms of worship; but he unseated the Patriarch, and appointed instead a consistory, the members of which were nominated by himself. Like Henry VIII., he virtually made himself the head of the Church,--that is, the supreme direction of ecclesiastical affairs was given to those whom he controlled, and not to the Patriarch, whose power had been supreme in religious matters,--more than Papal, almost Druidical. In former reigns the Patriarch had the power of life and death in his own tribunals; and when he rode to church on Palm Sunday, in his emblazoned robes, the Czar walked uncovered at his side, and held the bridle of his mule. It is a mark of the extraordinary power of Peter that he was enabled to abolish this great dignity without a revolution or bloodshed; and he not only abolished the patriarchal dignity, but he seized the revenues of the Patriarch, taxed the clergy, and partially suppressed monasteries, decreeing that no one should enter them under fifty years of age; yea, he even decreed universal toleration of religion, except to the Jesuits, whom he hated, as did William III. and Frederic II. He caused the Bible to be translated into the Slavonic language, and freely circulated it. And he prosecuted these reforms while he was meditating, or was engaged in, great military enterprises.
