A unique and comprehensive study, One Hundred Years of Socialism traces the fortunes of the political parties on the left in Western Europe through the twentieth century. From the Second International to the birth of the welfare state to the student uprisings of the 1960s and beyond, acclaimed historian Donald Sassoon charts the course of socialism across fourteen countries, showing us both the origins of Western socialism and its considerable accomplishments, particularly since 1945. One Hundred Years of Socialism is an essential account of the love/hate relationship between capitalism and socialism in twentieth century Western Europe.
