Iranian wedding (Persian: مراسم عروسی در ایران), also known as Persian wedding, consists of traditions that go back to Zoroastrianism, which was the main religion of pre-Islamic Iran, and although the concepts 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 observed by the majority of ethnic groups in Iran.
