How did Sara Lidman's writing shift between the 1950s and the late 1970s?

Sara Lidman’s literary career underwent a significant transformation between the 1950s and the late 1970s, characterized by a shift from regional fiction to political activism and a subsequent return to creative storytelling.12

• 1950s: Lidman established herself as a prominent novelist with works such as Tjärdalen (1953) and Hjortronlandet (1955). These early novels were deeply rooted in the rural life of her native northern Sweden, blending realism with a biblical tone and a fairy-tale atmosphere.1
• 1960s and 1970s: During this period, Lidman largely abandoned fiction to engage in political debate and social criticism. She traveled to Africa and North Vietnam, producing works that protested international injustices and oppression, such as Samtal i Hanoi (1966) and Fåglarna i Nam Dinh (1972). She also focused on domestic social conditions, notably in her study of iron miners, Gruva (1968).12
• Late 1970s: Lidman returned to creative literature, initiating a new series of novels set in her home district. These works, including Din tjänare hör (1977) and Vredens barn (1979), revisited the themes of her early career, depicting preindustrial history and provincial life with renewed narrative passion.12
