Explanation:

The February Revolution was the first of two revolutions which took place in Russia in 1917.

The main events of the revolution took place in and near Petrograd (present-day Saint Petersburg), the then-capital of Russia, where long-standing discontent with the monarchy erupted into mass protests against food rationing on 23 February. Revolutionary activity lasted about eight days, involving mass demonstrations and violent armed clashes with police and gendarmes, the last loyal forces of the Russian monarchy. On 27 February mutinous Russian Army forces sided with the revolutionaries. Three days later Tsar Nicholas II abdicated, ending Romanov dynastic rule and the Russian Empire. A Russian Provisional Government under Prince Georgy Lvov replaced the Council of Ministers of Russia.
