Swedish novelist and dramatist, best-known for his novels of the Swedish emigration to America but concerned primarily with the people of the countryside from which he came and with the system that made life so miserable for them.

In his autobiographical novel, Soldat med brutet gevär (1944; When I Was a Child), Moberg considers it his calling to give a voice to the illiterate class from which he came. His most widely read and translated works include the Knut Toring trilogy (1935–39; The Earth Is Ours) and his four-volume epic of the folk migration from Sweden to America in the 1850s, Utvandrarna (1949–59; The Emigrants), Invandrarna (1952; Unto a Good Land), Nybyggarna (1956), and Sista brevet till Sverige (1959). The last two volumes were combined in the translation The Last Letter Home. During World War II, Moberg also wrote a novel eloquently attacking tyranny and oppression, Rid i natt! (1941; Ride This Night!), in which he dramatizes the necessity of men acting in the cause of freedom and justice.
