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.
St. Petersburg, Florida
St. Petersburg was founded in 1888 by John C. Williams, who purchased the land, and by Peter Demens, who brought the railroad industry into the area. As a part of a coin toss bet, the winner, Peter Demens, named the land after Saint Petersburg, Russia, while Williams opted to name the first hotel built which was named the Detroit Hotel, both named after their home towns respectively. St. Petersburg was incorporated as a town on February 29, 1892 and re-incorporated as a city on June 6, 1903.
