Political map of Russia & the former Soviet Union 08 March 1917 (February Revolution): By February 1917 (according to the old style Julian calendar still in use in Russia), the Tsarist system was on the brink of collapse. Russia's troops were demoralized, its economy was crumbling, and discontent was everywhere. On 8 March (23 February old style) (February revolution), riots broke out in Petrograd, the capital, and within two days the city had been almost completely closed down. Tsar Nicholas II's attempts to end the disorder simply resulted in troop mutinies and the disintegration of the police force. On the 15th, the Tsar abdicated and the Provisional Government (Russian Provisional Government) of Prince George Lvov, Paul Milivkov and Alexander Kerensky took over.
