The class struggle (Erfurt program)

The official commentary of the Social Democratic Party of Germany (SPD) on their Erfurt Program from 1891. The seminal (and popular) text for Orthodox Marxism and the Second International. Historian Donald Sassoon wrote it “became one of the most widely read texts of socialist activists throughout Europe” and Kautsky's commentary “was translated into sixteen languages before 1914 and became the accepted popular summa of Marxism” around the world.
