Friedrich Kratochwil is the author of the classic book: Rules, Norms and Decisions (1989), which introduced constructivism to international relations and has had a profound and significant impact on the discipline.

The Puzzle of Politics brings together for the first time a collection of his key essays to explain his approach to international relations and how his thinking has developed over the last 30 years. It addresses topical themes and issues central to his work including sovereignty, law, epistemology, boundaries, global governance and world society.

The book includes a framing introduction written for this volume in which Kratochwil provides an intellectual biography providing context as well as an introduction to his work.

This important volume will be of very strong interest to students and scholars of international relation, political theory and law.
