This chapter develops Sturm's notion of geopolitical religion, and hence religious and spiritual discourses and practices which give meaning to, predict or seek to intervene in the relations between nations and the map of political spaces. It aims to explore how religious and spiritual actors give meaning to, practice and create visions of geopolitical space, and how they seek to enact religious and political power both within and beyond the nation. The chapter analyses a particular example of occult geopolitics – Dion Fortune's Fraternity of Inner Light and what has become known as the 'Magical Battle of Britain' – which sought to direct the course of World War Two through connecting to and manipulating an esoteric topology of unseen forces. The philosopher, mathematician, astrologer, alchemist and geographer Dr John Dee is a widely acknowledged thinker whose magical and occult work entwines in many ways with geopolitics.
