International Relations Theory offers a unique approach to help students think conceptually and critically about how our contemporary world of diverse state and non-state actors works, but also the implications of domestic and global changes. The seventh edition covers current IR theory images (realism, liberalism, economic-structuralism, and the English School), interpretive understandings (constructivist, feminist, postmodern, critical theory, and green theory), normative considerations, and intellectual foundations from the ancient world to the modern era.
