Iranian wedding (Persian: مراسم عروسی در ایران), also known as Persian wedding, consists of traditions rooted in Zoroastrianism, the primary religion of pre-Islamic Iran. Though the concepts and theories of marriage have been changed by Islamic traditions, the ceremonies have remained more or less the same as they were originally in pre-Islamic Iran. Although modern-day Iran is a multi-ethnic country (see also Azeri wedding), Iranian wedding traditions are embraced by the majority of ethnic groups in Iran.
