The February Revolution was a bourgeois-democratic revolution that overthrew Tsar Nicholas Romanov and made up the first state of the Russian revolution of 1917, which culminated in the Great October Socialist Revolution.
On 8 March 1917, Petrograd had a shortage of fuel and food. Women working in the textile industry began a strike, and men and women from other industries soon joined. By 10 March, 50,000 workers were on strike, and Tsarism collapsed on 18 March.
The first leader of the provisional government was Georgy Lvov, an aristocratic prince, and his successor, Alexander Kerensky, was a liberal lawyer. Poliksena Shishkina-Iavein led a large demonstration on 19 March for equal rights, and a system of soviets formed dual power by April. Kerensky's government continued to support imperialism, leading the Bolsheviks to denounce it and call for another revolution.
