In Sweden, an early proponent of progressive education was Alva Myrdal, who with her husband Gunnar co-wrote Kris i befolkningsfrågan (1934), a most influential program for the social-democratic hegemony (1932–1976) popularly known as "Folkhemmet". School reforms went through government reports in the 1940s and trials in the 1950s, resulting in the introduction in 1962 of public comprehensive schools ("grundskola") instead of the previously separated parallel schools for theoretical and non-theoretical education.[33]
