The Soviet Union, established following the Revolution, lasted until 1991, and as a superpower exerted a huge influence across the world.

Almost every major war or power struggle bears relation to the events of 1917. Our panel, including author Pankaj Mishra, unpick this complex and dramatic history, and the present day legacy.
