This open access book explores the various manifestations of the archangel Michael in history, politics, and popular culture. One of the most venerated intermediate beings of the belief systems of all Christian traditions, the archangel Michael has assumed multiple roles that go far beyond the ways in which he has been defined by his major cults. Chapters explore how the archangel Michael has often accompanied processes of Christianization as well as being the divine messenger par excellence. Covering a broad variety of academic perspectives and historical contexts, the book explores how the archangel Michael has subsumed ancient cults, been endowed with magical and ritual powers and guided religious and secular leaders in their exploits. The figure of the archangel Michael is shown to have even inspired educational systems, and in more recent times become a "commercial brand" of blessings and protections. Going beyond orthodoxies, this book reveals how the history and interpretations of the Archangel's manifestations have been redefined by Christians of Adventist beliefs, by politicians using religious apocalypse in their rhetoric, and by New Age leaders in highly innovative and individualistic manners.
