In 1903, at the close of the Second Congress of the Russian Social Democratic Labour Party, the socialist party had split into two factions, those that would follow Lenin¿s proposed revolutionary path and those that would follow Iulii Martov¿a group that would call themselves the Mensheviks. In this edition, Martov¿s only book is ably translated by Paul Kellogg and Mariya Melentyeva, making it available in English in its complete form for the first time in a hundred years.
