The Union of Liberation (Russian: Союз Освобождения, English transliteration: Soyuz Osvobozhdeniya) was a liberal political group founded in St. Petersburg, Russia in January 1904. Its goal was originally the replacement of the absolutism of the Tsar with a constitutional monarchy. Its other goals included an equal, secret and direct vote for all Russian citizens and the self-determination of different nationalities (such as the Poles) that lived in the Russian State.
