Peter the Great
While the Poles fought the Swedes, Peter founded the city of Saint Petersburg in 1703, in Ingermanland (a province of the Swedish Empire that he had captured). It was named after his patron saint Saint Peter. He forbade the building of stone edifices outside Saint Petersburg, which he intended to become Russia's capital, so that all stonemasons could participate in the construction of the new city. Between 1713 and 1728 and in 1732–1918, Saint Petersburg was the capital of imperial Russia.
History of Saint Petersburg
The son of Emperor Nicholas I, Emperor Alexander II implemented the most challenging reforms undertaken in Russia since the reign of Peter the Great. The emancipation of the serfs (1861) caused the influx of large numbers of poor into the capital. Tenements were erected on the outskirts, and nascent industry sprang up, surpassing Moscow in population and industrial growth. By 1900, St. Petersburg had grown into one of the largest industrial hubs in Europe, an important international center of power, business and politics, and the 4th largest city in Europe.
