Anna Karenina, novel by Leo Tolstoy, published in installments between 1875 and 1877 and considered one of the pinnacles of world literature.The narrative centres on the adulterous affair between Anna, wife of Aleksey Karenin, and Count Vronsky, a young bachelor. Karenin’s discovery of the liaison arouses only his concern for his own public image. Anna promises discretion for the sake of her husband and young son but eventually becomes pregnant by Vronsky. After the child is born, Anna and the child accompany Vronsky first to Italy and then to his Russian estate. She begins making furtive trips to see her older child and grows increasingly bitter toward Vronsky, eventually regarding him as unfaithful. In desperation she goes to the train station, purchases a ticket, and then impulsively throws herself in front of the incoming train. A parallel love story, involving the difficult courtship and fulfilling marriage of Kitty and Levin, provides a rich counterpoint to the tragedy and is thought to reflect Tolstoy’s own marital experience.
