Polytheistic reconstructionism is an approach to modern paganism first emerging in the late 1960s to early 1970s, which gathered momentum starting in the 1990s. Reconstructionism attempts to re-establish genuine polytheistic religions in the modern world through a rediscovery of the rituals, practices and contextual worldviews of pre-Christian pagan religions. This method stands in contrast with other neopagan syncretic movements like Wicca, and ecstatic/esoteric movements like Germanic mysticism or Theosophy.

Modern paganism, also known as contemporary paganism and neopaganism, is a type of religion or family of religions influenced by the various historical pre-Christian beliefs of pre-modern peoples in Europe and adjacent areas of North Africa and the Near East. Although they share similarities, contemporary pagan movements are diverse and as a result, they do not share a single set of beliefs, practices, or texts. Scholars of religion often characterise these traditions as new religious movements. Some academics who study the phenomenon treat it as a movement that is divided into different religions while others characterize it as a single religion of which different pagan faiths are denominations.
