Polytheism is a religious belief system that recognizes the existence of several gods or deities. It stands in contrast to monotheism, which affirms the existence of a single God. The word comes from the Greek polys, meaning “many,” and theos, meaning “god.”
In polytheistic religions, deities may have different personalities, functions, and powers. Some are associated with forces of nature, such as the sun, the sea, or storms, while others are connected to love, war, fertility, wisdom, or the protection of human beings. They may be regarded as independent of one another, belong to the same divine family, or form part of a hierarchical structure dominated by a principal deity.
Polytheism does not, however, mean that believers must worship all deities equally. An individual may have a particularly close relationship with one god while recognizing the existence and importance of others. Religious practices vary according to communities, regions, families, and the circumstances of life.
Polytheism has played a major role in the religious history of humanity. In ancient Greece, the gods formed a group known as a pantheon. Zeus was regarded as the ruler of the gods, while Poseidon was associated with the sea, Athena with wisdom and the protection of certain cities, Apollo with music and divination, and Aphrodite with love. The Greeks dedicated temples to them, organized religious festivals, and presented offerings and sacrifices. These practices are documented by the Metropolitan Museum of Art.
Roman religion also included numerous deities, among them Jupiter, Juno, Mars, Venus, and Minerva. Several corresponded to Greek gods, although Roman traditions retained their own distinctive characteristics. The Romans also attached great importance to deities who protected the household, the family, and the city.
In ancient Egypt, deities such as Ra, Osiris, Isis, Horus, and Anubis fulfilled different functions in the organization of the world and in beliefs concerning death. Their importance varied according to historical periods and regions. Some gods could be associated or merged, as in the case of Amun and Ra, who became Amun-Ra. The British Museum presents this diversity through the principal Egyptian deities.
In Mesopotamia, the Sumerians, Babylonians, and Assyrians also recognized numerous gods. Among them were An, Enlil, Enki, Inanna, and Marduk. Each major city often had its own protective deity, and the importance of individual gods could change as political circumstances evolved. The Metropolitan Museum of Art highlights the connection between the power of cities and the position of their deities within the pantheon.
Polytheism, however, is not confined to the past.
Hinduism includes numerous traditions in which several deities are worshipped, notably Vishnu, Shiva, Devi, Ganesha, and Lakshmi. However, it would be inaccurate to describe Hinduism as a whole as simply polytheistic. Some schools recognize a supreme God, while others regard the different deities as manifestations of a single divine reality known as Brahman. Historian of religions Wendy Doniger discusses this diversity in her study Are Hindus Monotheists or Polytheists?.
Shinto, Japan’s traditional religion, recognizes a multitude of kami, sacred powers or presences associated particularly with nature, places, ancestors, and certain mythological figures. Kami do not always correspond to the Western conception of a personal god. Their veneration is expressed primarily through rituals, offerings, and festivals celebrated at shrines.
Some traditional African religions also recognize a plurality of divine powers. In the Yoruba religion, for example, the orishas occupy a central place in religious practices, alongside belief in a supreme being, Olodumare. This structure demonstrates that the presence of several deities or sacred powers does not necessarily imply the absence of a higher divine principle.
Polytheism also finds contemporary expression in various Neopagan movements. Some seek to revive ancient Greek, Roman, Norse, or Celtic religions, adapting their rituals to the modern world. However, not all Neopagan movements are polytheistic: some adopt pantheistic, monotheistic, or nontheistic conceptions.
Scholars also distinguish polytheism from henotheism, which gives a predominant position to one deity while recognizing the existence of other gods, and from monolatry, which involves the exclusive worship of a single god without necessarily denying the existence of others.
Polytheism should not be confused with animism, which recognizes a spiritual dimension in certain beings or elements of the natural world. These two conceptions may coexist, but they do not refer to exactly the same beliefs.
Finally, the distinction between monotheism and polytheism does not make it possible to classify every religion without difficulty. Some traditions combine the existence of several divine figures with the affirmation of a single overarching principle. Others do not place the concept of a god at the center of their beliefs.
Polytheism therefore represents one of the major ways in which religious beliefs are organized. Far from being merely a matter of multiplying gods, it encompasses a wide diversity of conceptions of the divine, ritual practices, and relationships between human beings and the sacred world.
