In 1935, the POUM, the Workers’ Party of Marxist Unification, was founded, playing a pivotal role at the outbreak of the Civil War and the revolution. Of the many dissident communist groups that began to emerge internationally in the 1930s, the POUM was the most important. This book by Andy Durgan tells the story of a revolutionary militancy of the first third of the 20th century, its party, its ideas, and its tragic fate. A story more relevant than ever in a world where the parallels with the 1930s, also threatened by the darkest reaction, compel us to read about that generation.
