伊朗人
Like other Indo-Europeans, the early Iranians practiced ritual sacrifice, had a social hierarchy consisting of warriors, clerics, and farmers, and recounted their deeds through poetic hymns and sagas. Various common traits can be discerned among the Iranian peoples. For instance, the social event of Nowruz is an ancient Iranian festival that is still celebrated by nearly all of the Iranian peoples. However, due to their different environmental adaptations through migration, the Iranian peoples embrace some degrees of diversity in dialect, social system, and other aspects of culture.
