The names of saints Peter and Paul, bestowed upon original city's citadel and its cathedral (from 1725—a burial vault of Russian emperors) coincidentally were the names of the first two assassinated Russian Emperors, Peter III (1762, supposedly killed in a conspiracy led by his wife, Catherine the Great) and Paul I (1801, Nicholas Zubov and other conspirators who brought to power Alexander I, the son of their victim).
The third emperor's assassination took place in Petersburg in 1881 when Alexander II fell victim to narodniki (see the Church of the Savior on Blood).
In 1716, Peter the Great appointed Frenchman Jean-Baptiste Alexandre Le Blond as the chief architect of Saint Petersburg.
The style of Petrine Baroque, developed by Trezzini and other architects and exemplified by such buildings as the Menshikov Palace, Kunstkamera, Peter and Paul Cathedral, Twelve Collegia, became prominent in the city architecture of the early 18th century.
By the 1840s, neoclassical architecture had given way to various romanticist styles, which dominated until the 1890s, represented by such architects as Andrei Stackenschneider (Mariinsky Palace, Beloselsky-Belozersky Palace, Nicholas Palace, New Michael Palace) and Konstantin Thon (Moskovsky railway station).
The project was not completed, but is evident in the layout of the streets.
Baroque architecture became dominant in the city during the first sixty years, culminating in the Elizabethan Baroque, represented most notably by Italian Bartolomeo Rastrelli with such buildings as the Winter Palace.
In the 1760s, Baroque architecture was succeeded by neoclassical architecture.
On November 7, 1917 (OS October 25), the Bolsheviks, led by Vladimir Lenin, stormed the Winter Palace in an event known thereafter as the October Revolution, which led to the end of the post-Tsarist provisional government, the transfer of all political power to the Soviets, and the rise of the Communist Party.
