Vera Ivanovna Zasulich was a Russian revolutionary and socialist activist. Born into impoverished nobility, Zasulich became involved in radical politics in the late 1860s. In 1878, she gained international renown for attempting to assassinate Fyodor Trepov, the governor of St. Petersburg, to protest his abuse of a political prisoner. In a high-profile case that highlighted the unpopularity of the tsarist government, a sympathetic jury acquitted her.
To avoid re-arrest, Zasulich fled to Western Europe, where she became a key figure in the populist Black Repartition movement. Disillusioned with terrorism as a revolutionary tactic, she converted to Marxism and in 1883 co-founded the Emancipation of Labour group, the first Russian Marxist organization, with Georgi Plekhanov and Pavel Axelrod.
