sentences:  Swedish proletarian literature is perhaps most closely associated with Ivar Lo-Johansson, who wrote about the lives of statare in his acclaimed novel "Godnatt, jord" ("Goodnight, earth", 1933) and in many short stories, collected in the books "Statarna" (1936–1937) and "Jordproletärerna" ("Proletarians of the Earth", 1941).Jan Fridegård also wrote about the lives of statare and is best known for a series of autobiographical novels beginning with "Jag Lars Hård" ("I Lars Hård", 1935).His first novel "En natt i juli" ("A night in July", 1933) is about a strike among statare, and depicts statare in a much rawer way than Lo-Johansson.
