while supporting ethical and social progressive reforms. Both of these latter schools tend to center the Gathas without outright rejecting other texts except the Vendidad. The Ilm-e-Khshnoom and the Pundol Group are Zoroastrian mystical schools of thought popular among a small minority of the Parsi community inspired mostly by 19th-century theosophy and typified by a spiritual ethnocentric mentality. From the 19th century onward, the Parsis gained a reputation for their education and widespread influence in all aspects of society. They played an instrumental role in the economic development of the region over many decades; several of the best-known business conglomerates of India are run by Parsi-Zoroastrians, including the Tata, Godrej, Wadia families, and others. Though the Armenians share a rich history affiliated with Zoroastrianism (that eventually declined with the advent of Christianity), reports indicate that there were Zoroastrian Armenians in Armenia until the 1920s. A comparatively minor population persisted in Central Asia, the Caucasus, and Persia, and a growing large expatriate community has formed in the United States mostly from India and Iran, and to a lesser extent in the United Kingdom, Canada and Australia. At the request of the government of Tajikistan, UNESCO declared 2003 a year to celebrate the "3000th anniversary of Zoroastrian culture", with special events throughout the world. In 2011 the Tehran Mobeds Anjuman announced that for the first time in the history of modern Iran and of the modern Zoroastrian communities worldwide, women had been ordained in Iran and North America as mobedyars, meaning women assistant mobeds (Zoroastrian clergy). The women hold official certificates and can perform the lower-rung religious functions and can initiate people into the religion. Relation to other religions and cultures Indo-Iranian origins The religion of Zoroastrianism is closest to Vedic religion to varying degrees. Some historians believe that Zoroastrianism, along with similar philosophical revolutions in South Asia were interconnected strings of reformation against a common Indo-Aryan thread. Many traits of Zoroastrianism can be traced back to the culture and beliefs of the prehistorical Indo-Iranian period, that is, to the time before the migrations that led to the Indo-Aryans and Iranics becoming distinct peoples. Zoroastrianism consequently shares elements with the historical Vedic religion that also has its origins in that era. Some examples include cognates between the Avestan word Ahura ("Ahura Mazda") and the Vedic Sanskrit word Asura ("demon; evil demigod"); as well as Daeva ("demon") and Deva ("god") and they both
