Nikolay Platonovich Ogarev (Ogaryov; December 6 [O.S. November 24] 1813 – June 12 [O.S. May 31] 1877) was a Russian poet, historian and political activist.
He is deeply critical of the limitations of the Emancipation reform of 1861, claiming that the serfs are not free but have simply exchanged one form of serfdom for another.
Ogarev is a fellow-exile and collaborator of Alexander Herzen on Kolokol, a newspaper printed in England and smuggled into Russia.
The two young men had sworn on the Sparrow Hills above Moscow in 1840 not to rest until their country is free; the oath reportedly sustains them and their friends throughout many crises of their lives at home and abroad and is described in E. H. Carr's The Romantic Exiles.
