Wicca in the context of "Nature worship"

Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries (Bosnia and Herzegovina, Kosovo and Albania) have Muslim majorities, with Christianity being the second-largest religion in those countries. Transcontinental nations between Europe and Asia also have muslim majorities, such as Turkiye and Azerbaijan, or large muslim minorities, such as Cyprus (including a de facto majority in the generally unrecognised Northern Cyprus) and Georgia.

Little is known about the prehistoric religion of Neolithic Europe. Bronze and Iron Age religion in Europe as elsewhere was predominantly polytheistic and included Ancient Greek religion, Ancient Roman religion, Slavic paganism, Finnish paganism, Celtic polytheism and Germanic paganism. Modern revival movements of these religions, and religions influenced by them, include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and Hetanism.

While the word religion is difficult to define and understand, one standard model of religion that is used in religious studies courses defines it as

Many religions have their own narratives, symbols, traditions and sacred histories that are intended to give meaning to life or to explain the origin of life or the universe. They tend to derive morality, ethics, religious laws, or a preferred lifestyle from their ideas about the cosmos and human nature. According to some estimates, there are roughly 4,200 religions, churches, denominations, religious bodies, faith groups, tribes, cultures, movements, or ultimate concerns.

Diana is a goddess in Roman religion, primarily considered a patroness of the countryside and nature, hunters, wildlife, childbirth, crossroads, the night, and the Moon. She is equated with the Greek goddess Artemis, and absorbed much of Artemis' mythology early in Roman history, including a birth on the island of Delos to parents Jupiter and Latona, and a twin brother, Apollo, though she had an independent origin in Italy.

Diana is revered in modern neopagan religions including Roman neopaganism, Stregheria, and Wicca. In the ancient, medieval, and modern periods, Diana has been considered a triple deity, merged with a goddess of the moon (Luna/Selene) and the underworld (usually Hecate).

Polytheistic reconstructionism (or simply 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.

While the emphasis on historical accuracy may imply historical reenactment, the difference between these two movements can be summarized as one of intent. Historical reenactment seeks historical accuracy as a goal in and of itself. On the other hand, a reconstructionist neopagan views historical accuracy as a means to the end of establishing a harmonious relationship between a belief-community and the gods.

Modern paganism, also known as neopaganism and contemporary paganism, is a range of new religious movements variously influenced by the beliefs of pre-modern peoples across Europe, North Africa, and the Near East. Despite some common similarities, contemporary pagan movements are diverse, sharing no single set of beliefs, practices, or religious texts. Scholars of religion may study the phenomenon as a movement divided into different religions, while others study neopaganism as a decentralized religion with an array of denominations.

Adherents rely on pre-Christian, folkloric, and ethnographic sources to a variety of degrees; many of them follow a spirituality that they accept as entirely modern, while others claim to adhere to prehistoric beliefs, or else, they attempt to revive indigenous religions as accurately as possible. Modern pagan movements are frequently described on a spectrum ranging from reconstructive, which seeks to revive historical pagan religions; to eclectic movements, which blend elements from various religions and philosophies with historical paganism. Polytheism, animism, and pantheism are common features across pagan theology. Modern pagans can also include atheists, upholding virtues and principles associated with paganism while maintaining a secular worldview. Humanistic, naturalistic, or secular pagans may recognize deities as archetypes or useful metaphors for different cycles of life, or reframe magic as a purely psychological practice.

Modern paganism, also known as "contemporary" or "neopagan", encompasses a wide range of religious groups and individuals. These may include old occult groups, those that follow a New Age approach, those that try to reconstruct old ethnic religions, and followers of the pagan religion or Wicca.

Reincarnation, also known as rebirth or transmigration, is the philosophical or religious concept that the non-physical essence of a living being begins a new lifespan in a different physical form or body after biological death. In most beliefs involving reincarnation, the soul of a human being is immortal and does not disperse after the physical body has perished. Upon death, the soul merely transmigrates into a newborn baby or into an animal to continue its immortality. (The term "transmigration" means the passing of a soul from one body to another after death.)

Reincarnation (punarjanman) is a central tenet of Indian religions such as Hinduism, Buddhism, Jainism, and Sikhism. In various forms, it occurs as an esoteric belief in many streams of Judaism, in certain pagan religions (including Wicca), and in some beliefs of the Indigenous peoples of the Americas and of Aboriginal Australians (though most believe in an afterlife or spirit world). Some ancient Greek historical figures, such as Pythagoras, Socrates, and Plato, expressed belief in the soul's rebirth or migration (metempsychosis).
