On 8 March 1917 (23 February in the Russian calendar) a protest by women workers demanding bread in Petrograd grew into a general strike. When the soldiers of the capital, ordered to suppress it, went over to the crowds, the government was powerless. Delegates of workers and soldiers formed the Petrograd Soviet, and members of the Duma set up a Provisional Government.
On 15 March (2 March) Nicholas II abdicated, ending the Romanov dynasty after more than three hundred years. A Provisional Government led by liberals and a Soviet led by socialists now shared authority — the so-called “dual power”.
The Provisional Government granted freedom of speech and assembly, but kept its promises to the Allies and went on fighting, and it put off land reform until a Constituent Assembly. Returning from exile in April, Lenin called for “All power to the Soviets” in his April Theses. When an offensive launched by Kerensky, prime minister from July, also failed, support for the Bolsheviks grew rapidly.
