Hardly is a figure more maligned in British history than Robert Stewart, Viscount Castlereagh. One of the central figures of the Napoleonic Era and the man primarily responsible for fashioning Britain's strategy at the Congress of Vienna, Castlereagh was widely respected by the great powers of Europe and America, yet despised by his countrymen and those he sought to serve. A shrewd diplomat, he is credited with being one of the first great practitioners of Realpolitik and its cold-eyed and calculating view of the relations between nations. Over the course of his career, he crushed an Irish rebellion and abolished the Irish parliament, imprisoned his former friends, created the largest British army in history, and redrew the map of Europe. Today, Castlereagh is largely forgotten except as a tyrant who denied the freedoms won by the French and American revolutions. John Bew's fascinating biography restores the statesman to his place in history, offering a nuanced picture of a shy, often inarticulate figure whose mind captured the complexity of the European Enlightenment unlike any other. Bew tells a gripping story, beginning with the Year of the French, when Napoleon sent troops in support of a revolution in Ireland, and traces Castlereagh's evolution across the Napoleonic Wars, the diplomatic power struggles of 1814-15, and eventually the mental breakdown that ended his life. Skillfully balancing the dimensions of Castlereagh's intellectual life with his Irish heritage, Bew's definitive work brings Castleragh alive in all his complexity, variety, and depth.

In her study of English theatre during the Peninsular War, Susan Valladares contextualizes the theatrical treatment of the war within the larger political and ideological axes of Romantic performance. From its nuanced reading of Richard Brinsley Sheridan's Pizarro (1799), to its accounts of wartime productions of Shakespeare, description of performances at the minor theatres, and detailed case study of dramatic culture in Bristol, Valladares’s book reveals how theatrical entertainments reflected and shaped public feeling on the Peninsular campaign.

The Office of Ordnance has been ill-served by previous accounts of its role in arming the Royal Navy during the French Revolution and Napoleonic Wars. Cole offers an in-depth examination of its organizational structure and demonstrates how the department responded to the pressures of war over an extended period of time.

An argument that the gas industry was the first integrated large-scale technological network and that it signaled a new wave of industrial innovation. In Progressive Enlightenment, Leslie Tomory examines the origins of the gaslight industry, from invention to consolidation as a large integrated urban network. Tomory argues that gas was the first integrated large-scale technological network, a designation usually given to the railways. He shows how the first gas network was constructed and stabilized through the introduction of new management structures, the use of technical controls, and the application of means to constrain the behavior of the users of gas lighting. Tomory begins by describing the contributions of pneumatic chemistry and industrial distillation to the development of gas lighting, then explores the bifurcation between the Continental and British traditions in distillation technology. He examines the establishment and consolidation of the new industry by the Birmingham firm Boulton & Watt, and describes the deployment of the network strategy by the entrepreneur Frederick Winsor. Tomory argues that the gas industry represented a new wave of technological innovation in industry because of its dependence on formal scientific research, its need for large amounts of capital, and its reliance on business organization beyond small firms and partnerships—all of which signaled a departure from the artisanal nature and limited deployment of inventions earlier in the Industrial Revolution. Gas lighting was the first important realization of the Enlightenment dream of science in the service of industry.
