The theory, practice and origin of sacral kingship have provided a source of lively controversy ever since enthusiasm for the ancient history of the Near East was first kindled in the early nineteenth century by the expedition of Napoleon to Egypt, but the discussion has been more fruitful following the publication of the pioneer anthropological work The Golden Bough, which suggested new lines of approach. It is now generally accepted that, when incipient communities larger than the clan or family group came into existence, a priest or warchief would emerge set apart to some extent from the people, and regarded as possessing supernatural powers of magic through his contact with the elemental forces or deities believed to surround human life on every side. Such beliefs were too widespread and durable for it to be possible to seek a common geographical area of origin.
