Nikolay Platonovich Ogarev (Ogaryov; Russian: Никола́й Плато́нович Огарёв; December 6 [O.S. November 24] 1813 – June 12 [O.S. May 31] 1877) was a Russian poet, historian and political activist. He was deeply critical of the limitations of the Emancipation reform of 1861, claiming that the serfs were not set free, but had simply exchanged one form of serfdom for another. Ogarev was a fellow-exile and collaborator of Alexander Herzen on Kolokol, a newspaper printed in England and smuggled into Russia. In the summer of 1827, during a walk in the Sparrow Hills above Moscow, Herzen and Ogarev made an oath not to rest until their country was free; the oath reportedly sustained them and their friends throughout many crises of their lives at home and abroad and was described in E. H. Carr's The Romantic Exiles. Source: Wikipedia (en)
