The first Swedish preschool for young children was established in 1836 to provide a practical solution to the problem of child supervision during the Industrial Revolution. During this period of intense industrialization, women began working in urban factories and thus required daytime childcare. A century later, in the 1930s, the Swedish idea of family policy was challenged by sociologists Alva and Gunnar Myrdal. They had a political vision of public childcare and championed a scientific approach to child development. A social pedagogical preschool was developed, emphasizing children’s right to an inspiring environment outside of the home. National reforms were implemented, establishing child health centers, child benefits for all children, and municipal grants for preschool teachers’ salaries.
