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.

While previous scholars of international history had focused on "great men" and their achievements, Paul Kennedy focused on the interdependent relationship between military might and economic growth. In his 1987 work, The Rise and Fall of the Great Powers, he shows why countries that balance the economic and the military can become "great powers." Those that fail to do so, however, risk imperial overstretch and failure.

i>Imagined Communities, Benedict Anderson's brilliant book on nationalism, forged a new field of study when it first appeared in 1983. Since then it has sold over a quarter of a million copies and is widely considered the most important book on the subject. In this greatly anticipated revised edition, Anderson updates and elaborates on the core question: What makes people live and die for nations, as well as hate and kill in their names?

Frantz Fanon's Black Skin, White Masks offers a radical analysis of the psychological effects of colonization on the colonized. Born in 1925 on the island of Martinique - at the time a French colony - Fanon witnessed firsthand the abuses of white colonizers and the system's effects on his country. His revulsion was only confirmed later in life when he worked as a psychiatrist in Algeria, another French colony. Fanon's work played a pivotal role in the civil rights movements of the 1960s and was later taken up by scholars of postcolonialist studies.

Western thinking about the Middle and Far East has been distorted by stereotype and inaccuracy. This argument lies at the center of Palestinian-American literary theorist Edward Said's groundbreaking book, Orientalism. Originally published in 1978, it cemented Said's reputation as the father of postcolonial studies.
