Xwedodah
Xwedodah (Persian: خویدوده khwēdōdah; Avestan: xᵛae¯tuuadaθa) is a type of consanguine marriage to have been historically practiced in Zoroastrianism before the Muslim conquest of Persia. 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.
This form of direct familial incest marriage allowed Zoroastrians to marry their sisters, daughters, granddaughters, and their own mothers to take as wives. 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. In modern Zoroastrianism it is near non-existent, having been noted to have disappeared as an extant practice by the 11th century.
