Mihail Alexandrovich Bakunin

In "Anarchism", by Daniel Guerin (Monthly Review Press, 1970), page 4, Guerin states, "The relative unity of Social Anarchism arises from the fact that it was developed during a single period by two masters, one of whom was a disciple of the other: the Frenchman Pierre-Joseph Proudhon (1809-1865) and the Russian exile Mikhail Bakunin (1814-1876). The latter defined anarchism as 'Proudhonism greatly developed and pushed to its furthest conclusion'. This type of anarchism called itself collectivist".
