In religious matters, the Tsar tolerated no division of power. There must be no chance of a rivalry between an Emperor and a Pope as had happened in Europe. In the year 1721, Peter made himself head of the Russian Church. The Patriarchate of Moscow was abolished and the Holy Synod made its appearance as the highest source of authority in all matters of the Established Church.

Since, however, these many reforms could not be successful while the old Russian elements had a rallying point in the town of Moscow, Peter decided to move his government to a new capital. Amidst the unhealthy marshes of the Baltic Sea the Tsar built this new city. He began to reclaim the land in the year 1703. Forty thousand peasants worked for years to lay the foundations for this Imperial city. The Swedes attacked Peter and tried to destroy his town and illness and misery killed tens of thousands of the peasants. But the work was continued, winter and summer, and the ready-made town soon began to grow. In the year 1712, it was officially declared to be the "Imperial Residence." A dozen years later it had 75,000 inhabitants. Twice a year the whole city was flooded by the Neva. But the terrific will-power of the Tsar created dykes and canals and the floods ceased to do harm. When Peter died in 1725 he was the owner of the largest city in northern Europe.
Of course, this sudden growth of so dangerous a rival had been a source of great worry to all the neighbours. From his side, Peter had watched with interest the many adventures of his Baltic rival, the kingdom of Sweden. In the year 1654, Christina, the only daughter of Gustavus Adolphus, the hero of the Thirty Years War, had renounced the throne and had gone to Rome to end her days as a devout Catholic. A Protestant nephew of Gustavus Adolphus had succeeded the last Queen of the House of Vasa. Under Charles X and Charles XI, the new dynasty had brought Sweden to its highest point of development. But in 1697, Charles XI died suddenly and was succeeded by a boy of fifteen, Charles XII.
This was the moment for which many of the northern states had waited. During the great religious wars of the seventeenth century, Sweden had grown at the expense of her neighbours. The time had come, so the owners thought, to balance the account. At once war broke out between Russia, Poland, Denmark and Saxony on the one side, and Sweden on the other. The raw and untrained armies of Peter were disastrously beaten by Charles in the famous battle of Narva in November of the year 1700. Then Charles, one of the most interesting military geniuses of that century, turned against his other enemies and for nine years he hacked and burned his way through the villages and cities of Poland, Saxony, Denmark and the Baltic provinces, while Peter drilled and trained his soldiers in distant Russia.
