Ivan the Fool is a fairy tale by Leo Tolstoy about three brothers: Semyon, a soldier; Taras, a merchant; and Ivan, a simple, hardworking fool. The Old Devil schemes to destroy the brothers' harmony, tempting each with money, power, and greed. While Semyon and Taras succumb to their vices, Ivan's simplicity and honesty prove immune to the Devil's tricks. The Devil's imps fail to corrupt Ivan's peasants, who value labor above wealth. Ultimately, Ivan's humility triumphs, and he creates a kingdom of contentment where honest laborers live peacefully. Tolstoy's tale champions simplicity, hard work, and moral integrity over greed and ambition.
