Lagerlöf made her debut in 1891 with The Gösta Berling saga, a story about her own region, Värmland and her home, the country manor Mårbacka. With her novel she starts the wave of romantic nationalist literature in Sweden of the 1890s. Her novel Jerusalem (1901-02) is about religious emigrants from Sweden to Palestine. She is the author of Sweden’s most read novel, The Adventures of Nils Holgerssons (1906), a story about a boy traveling across Sweden on the back of a goose. Her stories often evolve around folklore and supernatural events. One of the peaks in her career was her novel The Emperor of Portugal (1914). In 1907 she got a honorary degree at the University of Uppsala, in 1909 she got the Nobel Prize and 1914 she became a member of the Swedish Academy. Her home Mårbacka is now a museum visited by thousands of tourists every year.
