In each volume, an introductory essay outlines of history of the disciplines under discussion, and describes how changes and innovations in these disciplines have affected our lives. The biographies that follow are organized in an A-Z format: each biography is divided into a "life" section describing the individual's life and influences and a "legacy" section summarizing the impact of that individual's work throughout history. These biographies cover a diverse group of men and women from around the globe and throughout history. Franklin Delano Roosevelt, Mao Tse-tung and Genghis Khan are among the 200 well-known historical figures included in this volume. Examples of other lesser-known, yet important, individuals covered in this work are: Gustavas Adolphus, Swedish empire creator; Hatshepsut, queen of ancient Egyptian dynasty; and Jean Jaurès, French socialist leader and pacifist. Each synopsis provides information on each individual's enduring impact on the common understanding of fundamental themes of human existence.

After completing his research for Democracy in America, Alexis de Tocqueville turned to the French consolidation of its empire in North Africa, which he believed deserving of similar attention. Tocqueville began studying Algerian history and culture, making two trips to Algeria in 1841 and 1846. He quickly became one of France's foremost experts on the country and wrote essays, articles, official letters, and parliamentary reports on such diverse topics as France's military and administrative policies in North Africa, the people of the Maghrib, his own travels in Algeria, and the practice of Islam. Throughout, Tocqueville consistently defended the French imperial project, a position that stands in tension with his admiration for the benefits of democracy he witnessed in America. Although Tocqueville never published a book-length study of French North Africa, his various writings on the subject provide as invaluable a portrait of French imperialism as Democracy in America does of the Early Republic period in American history. In Writings on Empire and Slavery, Jennifer Pitts has selected and translated nine of his most important dispatches on Algeria, which offer startling new insights into both Tocqueville's political thought and French liberalism's attitudes toward the political, military, and moral aspects of France's colonial expansion. The volume also includes six articles Tocqueville wrote during the same period calling for the emancipation of slaves in France's Caribbean colonies.
