A modern edition on the 150th anniversary of the Manifesto. The Communist Manifesto, drafted on the eve of the 1848 revolutions, is the most brilliant and incisive political text ever written; a work of great literary power as well as historical insight. Eric Hobsbawm, whose writing has brilliantly described the century and a half of history that has been both shaped and illuminated by the Manifesto, presents it here. As the "age of extremes" draws to an end and capitalism seems everywhere to be triumphant, as it did one hundred and fifty years ago, Eric Hobsbawm critically appraises a work which, he argues, is now more timely than ever. Hobsbawm notes the curious fact that the Manifesto remained a subterranean text for many decades and did not circulate on a mass scale, or achieve a canonical status, until comparatively recently. He argues that only the complete unfolding of capitalism on a global scale in recent times allows us to take the full measure of Marx and Engels's truly astounding mixture of passion, science and poetry.
