Proto-Indo-Iranian religion means the religion of the Indo-Iranian peoples prior to the earliest Hindu and Zoroastrian scriptures. These share a common inheritance of concepts including the universal force *rta (Sanskrit rta, Avestan asha), the sacred plant and drink *sauma (Sanskrit Soma, Avestan Haoma) and gods of social order such as *mitra (Sanskrit Mitra, Avestan and Old Persian Mithra, Miϑra), *bhaga (Sanskrit Bhaga, Avestan and Old Persian Baga). Proto-Indo-Iranian religion is an archaic offshoot of Indo-European religion.
