History of Saint Petersburg
Founded by Tsar Peter the Great on 27 May 1703. It became capital of the Russian Empire for more than two hundred years (1712–1728, 1732–1918). St. Petersburg ceased being the capital in 1918 after the Russian Revolution of 1917.
Stavropol
It was founded on October 22, 1777 following the Russo-Turkish War of 1768–1774 as a military encampment, and was granted city status in 1785. Prince Grigory Potemkin, who founded Stavropol as one of ten fortresses built between Azov and Mozdok at the request of Catherine the Great, played a leading role in the creation of the city. Don Cossacks, particularly those from the Khopersky Regiment, settled the area in and around the cities of Stavropol and Georgiyevsk with a mission to defend borders of the Empire.
