clared 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.

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.

Charles continued to be a highly picturesque figure, a wonderful hero of romance, but in his vain attempt to have his revenge, he ruined his own country. In the year 1718, he was accidentally
