What happened
Peter I, Tsar since 1682, had spent time in Western Europe on his Grand Embassy studying shipbuilding and foreign institutions, and returned determined to modernize Russia. After going to war with Sweden for access to the Baltic Sea, he began building a fortress and port on the River Neva in May 1703 and named it St. Petersburg. He hired the Italian architect Domenico Trezzini, who spent nine years shaping the new city, and compelled hundreds of wealthy families and merchants to relocate there. In 1712, Peter made St. Petersburg the new capital of Russia, replacing Moscow.
Why it matters
St. Petersburg gave Russia a Baltic seaport built explicitly on Western European architectural models, physically embodying Peter's broader campaign of forced Westernization that touched the navy, the calendar, dress, and education. It remained the imperial capital for over two hundred years, until the Bolsheviks moved the seat of government back to Moscow in 1918.
How we know
Peter's own decrees and the accounts of foreign observers and the Italian architects and engineers he employed document the city's founding and rapid construction; the Peter and Paul Fortress from the original 1703 project still stands today.
