Anna Karenina follows the intertwined lives of Anna, a noblewoman who enters a passionate but socially ruinous affair with Count Vronsky, and Konstantin Levin, whose search for meaning offers a philosophical counterpoint. Through these parallel stories, Tolstoy explores love, family, infidelity, societal pressure, and the tension between personal desire and moral duty. Set against the sweeping backdrop of Imperial Russia, the novel blends emotional depth, psychological realism, and social critique, making it one of world literature’s greatest works.
