James Harrington's brief career as a political and historical theorist spans the last years of the Cromwellian Protectorate and the Restoration of 1660. This volume comprises the first and last of Harrington's writings. Harrington was the first theorist to interpret the English Civil Wars as a revolution, the result of a long-term process of social change which led to the decay of the old political order. The Commonwealth of Oceana (1656) is a fictionalised presentation of English history up to the victory of the New Model Army, explaining the fall of the monarchy and proposing a republic to replace it. A System of Politics, written after the Restoration, is a scheme of history and political philosophy erected on the foundations of his previous works. Professor Pocock's introduction emphasises Harrington's place as a pivotal figure in the history of English political thought. This edition also contains a chronology of events in Harrington's life and a guide to further reading.

Despite not being an active participant in the English Civil War, seventeenth-century political thinker James Harrington exercised an important influence on the ideas and politics of that crucial period of history. In The Commonwealth of Oceana he sought to explain why civil war had broken out in 1642, to put the case for commonwealth government, and to offer a detailed constitutional blueprint for a new and successful English government. In this intellectual biography of Harrington, Rachel Hammersley sets a fresh analysis of this and Harrington's other writings against the background of his life and the turbulent period in which he lived. In doing so, this study seeks to move beyond the conventional view of Harrington as primarily a republican thinker, offering a broader and more comprehensive account of him which addresses the complexity of his republicanism as well as exploring his contributions to economic, historical, religious, philosophical, and scientific debates; his experimentation with vocabulary and literary form; and the relationship between his life and thought. Harrington is presented as an innovative political thinker, committed to democracy, social mobility, and meritocracy. Ultimately, this broader examination of Harrington's life and work opens a window on political, economic, religious, and scientific issues which serve to complicate understandings of the English Revolution, and sheds fresh light on the relevance of seventeenth-century ideas to the modern world.
