The city of St. Petersburg, Russia, was founded in 1703 by Peter the Great, hence the name, St. Petersburg. But it wasn't always that simple. In 1914, at the beginning of World War I, Russian leaders felt that Petersburg was too German-sounding. So they changed the name of the city to Petrograd -- to make it more Russian-sounding. Then, in 1924, the country's Soviet Communist leaders wanted to honor the founder of the Soviet Union, Vladimir I. Lenin. The city of Petrograd became Leningrad and was known as Leningrad until 1991 when the new Russian legislators -- no longer Soviet Communists -- wanted the city to reflect their change of government, so they changed the name back to St. Petersburg.
