First published in Germany in 1980, British historian Ian Kershaw's The "Hitler Myth" is recognized as one of the most important books ever written about Adolf Hitler and the Nazi State. Kershaw wanted to focus on what he called the "history of everyday life", and so investigated the attitude of the German public to Hitler at the time, rather than looking at the dictator from the perspective of those in positions of power. He was intrigued to find out how someone like Hitler could have become such a powerful figure.

British-born American political activist Thomas Paine wrote Rights of Man in 1791 in response to Reflections on the Revolution in France, Edmund Burke's attack on the French Revolution. Burke was wary of tearing down old institutions of government. But Paine argued that revolution is acceptable - in fact, necessary - when government ignores the rights of its people. Not surprisingly, Rights of Man proved very popular in the newly liberated United States, selling over 100,000 copies.

Kenneth Waltz's Theory of International Politics created a "scientific revolution" in international relations, starting two major debates. In the 1980s it defined the controversy between the neorealists, who believed that competition between states was inevitable, and the neoliberals, who believed that states could cooperate with each other. As the debate wound down with the end of the Cold War in the 1990s, a second more fundamental debate began.

US psychologist Abraham Maslow's 1943 essay "A Theory of Human Motivation" established his idea of humanistic psychology as a "third force" in the field. He outlined a new approach to understanding the mind, saying humans are motivated by their need to satisfy a series of hierarchical needs, starting with the most essential first. He thought it important for the advancement of psychology to identify, group, and rank them in terms of priority.

Michael R. Gottfredson and Travis Hirschi's 1990 work, A General Theory of Crime, assessed contemporary work in criminology, while also introducing a new, comprehensive theory of crime. At the time, researchers tended to focus on environmental factors that led to crime, not on the criminals themselves. Additionally, crime researchers came from different disciplines and inclined towards thinking about crime only from their particular perspective. This meant ideas about what caused crime, and how to prevent it, were often in conflict.
