Saint Petersburg
Saint Petersburg has changed its name many times. During World War I, when Russia and Germany were fighting each other, Russians thought the name Sankt Peterburg sounded too German, so Tsar Nicholas II, on August 31 (August 18, Old Style), 1914 decided that the city was renamed Petrograd.  In 1918 during the Russian revolution, the Soviet capital was moved to Moscow, still the capital of Russia now.
