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.
Military history of the Russian Empire
The epoch of Russian history that Peter created has been variously known as the Imperial Age, because of the new connection between the ruler and land; the St. Petersburg Era, as the capital was moved to the newly built Saint Petersburg during his reign; and the All-Russian Period, which stresses the greater hegemony founded in the previously xenophobic country. The period from the time of his rule to the October Revolution (and dissolution of the Russian Empire) in 1917 is also sometimes called the Petrine era, in tribute to his importance. However, the Russian Empire proper was not founded until Peter took the title of "imperator" (emperor), at the end of the Great Northern War.
