Lavr Georgiyevich Kornilov18 August 1870 – 13 April 1918) was a military intelligence officer, explorer, and general in the Imperial Russian Army during World War I and the ensuing Russian Civil War. He is today best remembered for the KornilovAffair, an unsuccessful endeavor in August/September 1917 that purported to strengthen Alexander Kerensky's Provisional Government, but which led to Kerensky eventually having Kornilov arrested and charged with attempting a coup d'état, and ultimately undermined the rule of Kerensky; strengthening the claims and power of the soviets, and the Bolshevik party.
Alexander Fyodorovich Kerensky 4 May 1881 – 11 June 1970) was a lawyer and major political leader before the Russian Revolutions of 1917 belonging to a moderate socialist party, called Trudoviks.
After the February Revolution Kerensky served as Minister of Justice in the democratic Russian Provisional Government. In May he became Minister of War. In July he became the second Prime Minister until it was overthrown by the Bolsheviks in the October Revolution. He spent the remainder of his life in exile, dying in New York City at the age of 89.
