The Swedish author Vilhelm Moberg in the mid-20th century wrote a series of four novels describing one Swedish family's migration from Småland to Minnesota in the late 19th century, a destiny shared by almost one million people. The author emphasizes the authenticity of the experiences as depicted (although he did change names). These novels have been translated into English ("The Emigrants", 1951, "Unto a Good Land", 1954, "The Settlers", 1961, "The Last Letter Home", 1961). The musical "Kristina från Duvemåla" by ex-ABBA members Björn Ulvaeus and Benny Andersson is based on this story.
