Syncretism () is the practice of combining different beliefs and various schools of thought. Syncretism involves the merging or assimilation of several originally discrete traditions, especially in the theology and mythology of religion, thus asserting an underlying unity and allowing for an inclusive approach to other faiths. Syncretism also occurs commonly in expressions of art and culture, known as eclecticism, as well as in politics, known as syncretic politics. Nomenclature The English word is first attested in the early 17th century, from Modern Latin , drawing on the , supposedly meaning "Cretan federation", but this is a spurious etymology from the naive idea in Plutarch's 1st-century AD essay on "Fraternal Love (Peri Philadelphias)" in his collection Moralia. He cites the example of the Cretans, who compromised and reconciled their differences and came together in alliance when faced with external dangers. "And that is their so-called Syncretism [Union of Cretans]". More likely as an etymology is sun- ("with") plus kerannumi ("mix") and its related noun, "krasis," "mixture." Social and political roles Overt syncretism in folk belief may show cultural acceptance of an alien or previous tradition, but the "other" cult may survive or infiltrate without authorized syncresis. For example, some conversos developed a sort of cult for martyr-victims of the Spanish Inquisition, thus incorporating elements of Catholicism while resisting it. The Kushite kings who ruled Upper Egypt for approximately a century and the whole of Egypt for approximately 57 years, from 721 to 664 BCE, constituting the Twenty-fifth Dynasty in Manetho's Aegyptiaca, developed a syncretic worship identifying their own god Dedun with the Egyptian Osiris. They maintained that worship even after they had been driven out of Egypt. A temple dedicated to this syncretic god, built by the Kushite ruler Atlanersa, was unearthed at Jebel Barkal. Syncretism was common during the Hellenistic period, with rulers regularly identifying local deities in various parts of their domains with the relevant god or goddess of the Greek Pantheon as a means of increasing the cohesion of their kingdom. This practice was accepted in most locations but vehemently rejected by the Jews, who considered the identification of Yahweh with the Greek Zeus as the worst of blasphemy. All major religious conversions of populations have had elements from prior religious traditions incorporated into legends or doctrine that endure with the newly converted laity.
