Barry Scott Zellen is an author, journalist, and political theorist specializing in the philosophy of war, the evolution of strategic theory, state-tribe conflict, and the tribal foundations of world order. Much of his early field work was rooted in the Arctic and Subarctic regions of North America, where he developed his ideas on the state-tribe interface, the tribal foundations of world order, and the persistence of tribal governance in remote regions well into the post-Westphalian era. He is a senior visiting fellow of the Anchorage-based Institute of the North and on the board of the Arctic Research Consortium of the United States (ARCUS).
