A cousin of Dmitri's mother, the wealthy Pyotr Miusov takes joint guardianship over Dmitri when his mother dies. Miusov spends most of his time in Europe and is consequently the most Europeanized of the characters. Liberal and progressive, atheist and socialist, Miusov detests Russian Orthodoxy as a backward, reactionary religion. But his behavior undercuts his so-called progressive values. He's a socialist who has no desire to give up his wealth, and his hatred for the Russian Orthodox Church could have something to do with the fact that he's in a land dispute with them.
