Lavrov was born into a military family of hereditary nobles. His father was a retired artillery officer of the
Imperial Russian Army and his mother was from a Russified Swedish merchant family. He entered a
military academy and graduated in 1842 as an army officer. He became well-versed in
natural science, history,
logic,
philosophy, and
psychology. He also taught mathematics for two decades, being a professor at the Artillery College in St. Petersberg. Lavrov joined the
revolutionary movement as a radical in 1862. He was arrested following
Dmitry Karakozov's failed attempt to assassinate
Alexander II. Letters and poems which were considered compromising had been found at his house and he was imprisoned in the military prison at St. Petersberg for nine months. No charge of being involved in the conspiracy was laid against him, but he was found guilty of having published subversive ideas and having shown sympathy with men of criminal tendencies. While in Paris, Lavrov fully committed himself to the revolutionary socialist movement. He became a member of the Ternes section of the
International Workingmen's Association in 1870. He was also present at the start of the 1871
Paris Commune, and soon went abroad to generate international support. Lavrov arrived in
Zürich in November 1872, and became a rival of
Mikhail Bakunin in the "Russian Colony". In Zürich he lived in the Frauenfeld house near the university. Lavrov tended more toward reform than revolution, or at least he saw reform as salutary. He preached against the conspiratorial ideology of
Peter Tkachev and others like him. Lavrov believed that while a
coup d'état would be easy in Russia, the creation of a socialist society needed to involve the Russian masses. He founded the journal
Vperyod! (lit. Forward!) in 1872, its first issue appearing in August 1873. Lavrov used this journal to publicize his analysis of Russia's special historical development. He spent time in London in 1877 and 1882. Lavrov wrote prolifically for more than 40 years. His works include
The Hegelian Philosophy (1858–59) and
Studies in the Problems of Practical Philosophy (1860). A contribution to the revolutionary cause,
Historical Letters (1870), was written under the pseudonym "Mirtov". The letters greatly influenced revolutionary activity in Russia. ==Revolutionary ideology==
