Aleksandra Lvovna Sokolovskaya (Russian: Александра Львовна Соколовская; 1872 – 29 April 1938 was a Russian Marxist revolutionary and Leon Trotsky's first wife. She perished in the Great Purges no earlier than 1938. Alexandra Lvovna had one of the most important positions in the South Russian Workers' Union. Her utter loyalty to socialism and her complete lack of any personal ambition gave her an unquestioned moral authority. The work that we were doing bound us closely together, and so, to avoid being separated, we had married in the transfer prison in Moscow.
