Lena massacre
The Lena Massacre or Lena Execution (Russian: Ленский расстрел, romanized: Lensky rasstrel) refers to the shooting of goldfield workers on strike in northeast Siberia near the Lena River on 17 April [O.S. 4 April] 1912.
The strike had been provoked by exceptionally harsh working conditions, and when the strike committee was arrested, a large crowd marched in protest. They were fired on by soldiers of the Imperial Russian Army, causing hundreds of casualties. The incident did much to stimulate revolutionary sentiment in Russia, and Alexander Kerensky's reporting of it in the Duma brought him to public notice for the first time.
