Recent years have seen a remarkable growth of interest in revolution and social upheaval. This collection of essays by distinguished historian and long-standing Marxist Eric Hobsbawm is a commentary and critical retrospective on the revolutionary movements and ideas that dominated the twentieth century, and which remain of crucial contemporary relevance. The essays here explore a broad range of related topics including the history of communism, the influence of marxism, insurrection, military coups and guerrilla warfare, and the role of intellectuals. This updated edition presents new thoughts on anti-communist polemics and the Spanish Civil War. Written with clarity and masterly assurance, Eric Hobsbawm's essays are indispensable for a true understanding both of twentieth-century history and of the pattern of events today.
