Sophia Lvovna Perovskaya (; – ) was a Russian Empire revolutionary and a member of the revolutionary organization Narodnaya Volya. She helped orchestrate the assassination of Alexander II of Russia, for which she was executed by hanging. Life as a revolutionary Perovskaya was born in Saint Petersburg, into an aristocratic family who were the descendants by the marriage of Elizabeth of Russia. Her father, Lev Nikolaievich Perovsky, was the military governor of Saint Petersburg. Her grandfather, Nikolay Perovsky, was a governor of Taurida. She spent her early years in the Crimea, where her education was largely neglected, but where she began reading serious books on her own. After the family moved to Saint Petersburg, Perovskaya entered the Alarchinsky Courses, a girls’ preparatory program. Here she became friends with several girls who were interested in the radical movement. She left home at the age of sixteen over her father's objections to her new friends. In 1871–1872, together with these friends, she joined the Circle of Tchaikovsky. In 1872–1873 and 1874–1877, she worked in the provinces of Samara, Tver, and Simbirsk. During this period, she received diplomas as a teacher and a medical assistant. A prominent fellow member of the Circle of Tchaikovsky, Peter Kropotkin, said the following of Perovskaya: In 1873, Perovskaya maintained several conspiracy apartments in Saint Petersburg for secret anti-tsarist propaganda meetings that had not been sanctioned by the authorities. In January 1874, she was arrested and placed in the Peter and Paul fortress in connection with the Trial of the 193. She was acquitted in 1877–1878. Perovskaya also took part in an unsuccessful attempt to free Ippolit Myshkin, a revolutionary and a member of Narodnaya Volya. In the summer of 1878, Perovskaya became a member of Zemlya i Volya, was soon arrested again, and banished to the Olonets Governorate. She managed to escape on her way to exile and went underground. As a member of Zemlya I Volya, Perovskaya went to Kharkov in order to organize the liberation of political prisoners from the central prison. In the fall of 1879, she became a member of the Executive Committee and later a member of the administrative committee of Zemlya i Volya. Perovskaya propagandized among students, soldiers, and workers, took part in organizing the Worker's Gazette, and maintained ties with political prisoners in Saint Petersburg.
