To conclude this part of our revolutionary ideas series, we explore the overlapping lives and thinking of two emblematic twentieth-century revolutionaries: Lenin and Trotsky. David talks to historian of Russia Edward Acton about what inspired them, what connected them and what divided them. How were they radicalised? How did they interpret the failure of the 1905 revolution? How did they make the 1917 revolution happen?Available from Saturday on PPF+: Lenin and Trotsky part 2, taking the story on from 1917 to explore civil war, the rise of Stalin and the re-invention of Trotskyism.
