Catherine Breshkovsky (real name Yekaterina Konstatinova Breshko-Breshkovskaya) (1844–1934) was a Russian revolutionary, better known as Babushka (Grandmother).
She left her home at the age of 26 to join followers of anarchist Mikhail Bakunin in Kiev. As Narodnik revolutionary, she was inprisoned 1874 at Katorga and exiled to Siberia in 1878. After her release in 1896, she formed a Socialist-Revolutionary group and helped to organize the Socialist-Revolutionary Party in 1901.
She escaped to Switzerland and the United States in 1900. After returning to Russia in 1905, she was captured and exiled to Siberia again. After 1917, revolution political prisoners were released and Breshkovsky was given a seat in Aleksandr Kerensky's government. When the bolsheviks came to power, Breshkovsky was again forced to flee.
She died in Czechoslovakia in 1934.
