“”The label polytheism is used where a plurality of gods are acknowledged and/or worshipped. Through the course of human history, polytheistic religions of one sort or another have been a dominant majority by far.

Polytheism is the belief that there is more than one god or goddess. This belief is held mostly by older religions, such as those of ancient Rome, Greece, and Egypt, and survives to modern times most notably in the Hindu and Shinto faiths, neopagan religions such as Wicca, Asatru and a range of tribal religions in areas like Africa.
 Roman "henotheism"
Contrary to popular opinion, Romans and Greeks of antiquity were not strict polytheists, but more comparable to "soft monotheists" with one divine presence and many smaller gods -- in its own way, similar to Hinduism. As historian Gillian Clark writes in Christianity and Roman Society (2004):
|Some modern writers use 'polytheist', but though there is a Greek adjective polutheos ('of many gods'), neither Greek nor Latin provided a word for someone who believes that there are many gods. Moreover, many philosophically trained Greeks and Romans were not, strictly speaking, polytheist, for they believed that the many gods of traditional cult were subordinates of the one god or manifestations of the single divine power. This position is sometimes called 'henotheist', a modern term for belief in one supreme god, as distinct from monotheist belief in only one god; it is also called 'soft monotheism', belief in one god that allows for lesser divine beings (Fowden 1998; Athanassiadi and Frede 1999, reviewed by T. Barnes 2001). It is comparable to versions of Jewish monotheism that give very high status to Moses or to the Messiah or to angels; or to some accounts of the relationship of Jesus Christ to God, especially when those accounts are combined with popular devotion to saints and angels (for cults of angels, see Peers 2001:6—9). Much recent scholarship argues that this 'soft monotheism' was widespread in the Roman world of the early centuries CE, so one reason for the success Of Christianity was that the ground was already prepared (Liebeschuetz 2000).|
 The nature of polytheism
Polytheism typically involves many gods or gods/goddesses with different functions. There is division of labour among the gods/goddesses. Different gods have different functions and believers pray to the relevant god/goddess depending on what they want. The divine entities typically are seen as part of a divine community or pantheon and there may be a divine ruler who leads the other gods. Gods from other religions are treated in differing ways:
- They may be identified with an existing gods/goddess from the pantheon.
- They may be incorporated into the pantheon.
- They may be considered unworthy of worship.
Polytheistic religions are inherently flexible. 
 Abrahamic religions
The Abrahamic religions developed largely among polytheistic religions (Canaanite, Roman, and Arab belief systems preceding Judaism, Christianity, and Islam), and the initial ancestor of Judaism may have been polytheistic up until the Deutoronomic reforms under King Josiah. The early books of the Old Testament make a lot more sense if one imagines that the writers believed YHWH to be just one of many limited, rival gods. Some Christian denominations, most notably Roman Catholicism, preserve a memory of polytheism in the veneration of Mary and of the Saints (many of whom are almost openly conflated with pre-Christian deities). Like polytheistic gods/goddesses the various male and female saints have specific functions and Roman Catholics pray to a saint who deals with their particular issue. Syncretistic religions with Catholic roots such as Santeria, and Vodoun, and Umbanda are essentially polytheistic religions (African-derived, in the case of the above three) combined with Christian names and worship forms.
 Polytheism in literature
Numerous writers, many based on questionable historical research, others as part of a science fiction or fantasy storyline, have related the gods of ancient mythology to presumed-real alien life forms or paranormal beings. Such theories, for example, have informed the works of historian/huckster Erich von Däniken, and were the basis for the Star Trek episode Who Mourns for Adonais?, Philip K. Dick's 1954 short story, Strange Eden, and much of the storyline of Stargate.
