The article studies the French pacifist Romain Rolland’s thoughts and writings on the Russian Revolution. He was convinced that Russian Revolution was the first great experiment of a social republic founded on work, but, because of his pacifism, he also questioned about the inevitable violence’s legitimacy. In addition, his visit to Stalin in the Thirties didn’t dissolve his doubts about the repression against political opponents. In public, he didn’t attack Russia, but however he silently expressed his dissent.
