Pagan studies is the multidisciplinary academic field devoted to the study of modern paganism, a broad assortment of modern religious movements, which are typically influenced by or claiming to be derived from the various pagan beliefs of premodern Europe. Pagan studies embrace a variety of different scholarly approaches to studying such religions, drawing from history, sociology, anthropology, archaeology, folkloristics, theology and other religious studies. The earliest academic studies of contemporary paganism were published between 1970 and 1980 by scholars like Margot Adler, Marcello Truzzi and Tanya Luhrmann, although it would not be until the 1990s that the actual pagan studies discipline properly developed, pioneered by academics such as Graham Harvey and Chas S. Clifton. Increasing academic interest in Paganism has been attributed to the new religious movement's increasing public visibility, as it began interacting with the interfaith movement and holding large public celebrations at sites such as Stonehenge. The first academic conference on the subject was held at the University of Newcastle upon Tyne, North-East England in 1993, followed three years later by a larger conference organised by the University of Lancaster in North-West England. Annual gatherings of the Conference on Current Pagan Studies and the Contemporary Pagan Studies Unit of the American Academy of Religion continue to develop scholarship in this field. In 2004, a peer-reviewed academic journal devoted to the discipline, The Pomegranate, began publication. Many books on the subject have been published by a variety of different academic publishing companies, while AltaMira Press began publication of the Pagan Studies Series. The relationship between pagan studies scholars and the contemporary pagan community which it studies has at times been strained, with some practitioners rejecting academic interpretations of their faiths. At the same time, many academics involved in Pagan studies are practicing pagans themselves, bringing an insider's perspective to their approaches.
