It and its 1972 sequel, The New Land (Nybyggarna), which were produced concurrently, are based on Vilhelm Moberg's The Emigrants, a series of novels about poor Swedes who emigrate from Småland, Sweden, in the mid-19th century and make their home in Minnesota. This film adapts the first two of the four novels–The Emigrants (1949) and Unto a Good Land (1952)–which depict the hardships the emigrants experience in Sweden and on their journey to America.
