Nikolai Sablin

Nikolai Alekseyevich Sablin (Russian: Никола́й Алексе́евич Са́блин), was the son of a petty landowner, was born in 1849 or 1850 (sources vary). While at Moscow University he became involved in revolutionary politics as a member of the Narodnaya Volya or People's Will.
Sablin went to Zurich in 1874 but returned to Russia the following year. He was arrested in March, 1875, but was not tried until January, 1878. He was found guilty but was soon released because of the long time he had been awaiting trial.
A member of People's Will, Sabin joined the plot to kill Alexander II. Others involved included Sophia Perovskaya, Andrei Zhelyabov, Gesya Gelfman, Ignaty Grinevitsky, Nikolai Kibalchich, Nikolai Rysakov, and Timofei Mikhailov.
On 15 March 1881, two days after Alexander II was assassinated, police raided the house where Sablin was living in common law marriage with Gesya Gelfman. Sablin killed himself with a revolver shot in the head before he could be arrested.
