The Russian Republic (Russian: Российская республика), or just Russia (Россия) was a state formed following the February Revolution of 1917. The Russian Empire collapsed, and Tsar Nicholas II abdicated. The new leadership was shared by the Provisional Government, led by Prince Georgy Lvov and later Alexander Kerensky, and the Petrograd Soviet, a council of leftist leaders. The Soviet planned to attempt a revolution, but their would-be leader, Vladimir Lenin, died of a stroke while in Switzerland. Kerensky disbanded the provisional government in October and formed a permanent one, with himself as the President of Russia.
