Building on A People’s History of the United States, this radical world history captures the broad sweep of human history from the perspective of struggling classes. An “indispensable volume” on class and capitalism throughout the ages—for readers reckoning with the history they were taught and history as it truly was (Howard Zinn) From the earliest human societies to the Holy Roman Empire, from the Middle Ages to the Enlightenment, from the Industrial Revolution to the end of the twentieth century, Chris Harman provides a brilliant and comprehensive history of the human race. Eschewing the standard accounts of “Great Men,” of dates and kings, Harman offers a groundbreaking counter-history, a breathtaking sweep across the centuries in the tradition of “history from below.” In a fiery narrative, he shows how ordinary men and women were involved in creating and changing society and how conflict between classes was often at the core of these developments. While many scholars see the victory of capitalism as now safely secured, Harman explains the rise and fall of societies and civilizations throughout the ages and demonstrates that history moves ever onward in every age. A vital corrective to traditional history, A People's History of the World is essential reading for anyone interested in how society has changed and developed and the possibilities for further radical progress.
