>Xwedodah (Persian: خویدوده xidude; Avestan: xᵛaētuuadaθa) is a type of consanguine marriage historically practiced in Zoroastrianism before the Muslim conquest of Persia.[1] Such marriages are recorded as having been inspired by Zoroastrian cosmogony and considered pious. It was a high act of worship in Zoroastrianism, and there were punishments for not performing it.[2][3]

>This form of direct familial incest marriage allowed Zoroastrians to marry their sisters, daughters, granddaughters, and their own mothers to take as wives.[4] Xwedodah was widely practiced by royalty and nobility, and possibly clergy, but it is not known if it was commonly practiced by families in other classes.[5] In modern Zoroastrianism it is near non-existent, having been noted to have disappeared as an extant practice by the 11th century.[5]
