First published in 1848, the The Communist Manifesto by Karl Marx and Friedrich Engels presents communism as a 'spectre' haunting Europe. During the century that followed, this revolutionary ideology swept the world and left an indelible mark on the geopolitical dynamics of the modern age. Historian Maurice J Casey talks to Danny Bird about the history of communism – from Bolshevik emigrés and the fall of the Berlin Wall; to the rise of the Comintern and the legacy of anticommunism.
