In The Age of Revolution, renowned British Marxist historian Eric Hobsbawm focuses on the historical period from the end of the 18th century to the middle of the 19th. He concludes that the "dual revolutions" of the time - the French Revolution and the British Industrial Revolution - changed the way the whole world thought about politics and power, and fundamentally shaped the modern era.

How do those in power exercise that power over a state's citizens? French thinker Michel Foucault's 1975 work Discipline and Punish looks to answer this question by investigating the prison system. Foucault does not believe that the modern-day system developed out of reformers' humanitarian concerns. He argues that prison both created and then became part of a bigger system of surveillance that extends throughout society.

In his 1996 book The Clash Of Civilizations and the Remaking of World Order, American political scientist Samuel Huntington sets out his vision of the post-Cold War world. While the era from 1945 to 1989 was shaped by ideological conflict (communism vs. capitalism), Huntington predicts a future of cultural conflict.

Environmental factors shape our history just as much as - and sometimes more than - human factors. That's the premise of Alfred W. Crosby's 1972 work The Columbian Exchange: Biological and Cultural Consequences of 1492, a key text in environmental history. While earlier scholars emphasized cultural and technological factors as defining the way our world developed, Crosby argues that nonhuman factors, such as the exchange of plants, animals, and microbes between the Old and New Worlds had more overall impact.
