Historian Kjell Östberg presents the first comprehensive study of one of the most influential political movements of our time. Swedish Social Democracy was an inspiration to young socialists around the world for generations. But little remains of the Swedish model today. For almost a century, Social Democracy prevailed in Sweden, which for many appeared to be on the verge of becoming a truly socialist country. What followed instead was a jarring adaptation to a rising neoliberal world order. Large parts of the public sector have now been privatised, social inequality is rapidly worsening, and right-wing populists have come to represent much of the working class. Östberg discusses the reformist strategy, class organizations and social mobilisation, women’s struggle, and the creation of the Swedish welfare society. It is a history emblematic of the transformations in global politics of the last half century.
