Ahura Mazda first appeared in the Achaemenid period (c. 550 - 330 BC) under Darius I's Behistun Inscription. Until Artaxerxes II of Persia (405-04 to 359-58 BC), Ahura Mazda was worshipped and invoked alone in all extant royal inscriptions. With Artaxerxes II, Ahura Mazda was invoked in a triad, with Mithra and Anahita. In the Achaemenid period, there are no known representations of Ahura Mazda at the royal court other than the custom for every emperor to have an empty chariot drawn by white horses, to invite Ahura Mazda to accompany the Persian army on battles. Images of Ahura Mazda, however, were present from the 5th century BC, but were stopped and replaced with stone carved figures in the Sassanid period and later removed altogether through an iconoclastic movement supported by the Sassanid dynasty.
'Ahura' is cognate with the Vedic word 'asura', both meaning 'lord'. Finnish Indologist, Asko Parpola, traces the etymological root of Asura to *asera- of Uralic languages, where it means 'lord, prince'.
Even though it is speculated that Ahura Mazda was a spirit in the Indo-Iranian religion, he had not yet been given the title of "uncreated spirit". This title was given by Zoroaster, who proclaimed Ahura Mazda as the uncreated spirit, wholly wise, benevolent and good, as well as the creator and upholder of Asha.
According to Zoroastrian tradition, at the age of 30, Zoroaster received a revelation: while fetching water at dawn for a sacred ritual, he saw the shining figure of the Amesha Spenta, Vohu Manah, who led Zoroaster to the presence of Ahura Mazda, where he was taught the cardinal principles of the "Good Religion" later known as Zoroastrianism. As a result of this vision, Zoroaster felt that he was chosen to spread and preach the religion. He stated that this source of all goodness was the Ahura worthy of the highest worship. He further stated that Ahura Mazda created spirits known as yazatas to aid him. Zoroaster proclaimed that some of the Iranian gods were daevas who deserved no worship. These "bad" deities were created by Angra Mainyu, the destructive spirit. The existence of Angra Mainyu was the source of all sin and misery in the universe. Zoroaster claimed that Ahura Mazda was not an omnipotent God, but used the aid of humans in the cosmic struggle against Angra Mainyu. Nonetheless, Ahura Mazda is Angra Mainyu's superior, not his equal. Angra Mainyu and his daevas, which attempt to attract humans away from the Path of Asha, would eventually be defeated.
Whether the Achaemenids were Zoroastrians is a matter of much debate. However, it is known that the Achaemenids were worshipers of Ahura Mazda. The representation and invocation of Ahura Mazda can be seen on royal inscriptions written by Achaemenid kings. The most notable of all the inscriptions is the Behistun Inscription written by Darius I which contains many references to Ahura Mazda. An inscription written in Greek was found in a late Achaemenid temple at Persepolis which invoked Ahura Mazda and two other deities, Mithra and Anahita.
Amongst the earliest surviving inscription, on the Elamite Persepolis Fortification Tablet 377, Ahura Mazda is invoked along with Mithra and Apam Napat, VedicVaruna ("moon-god"). Artaxerxes III makes this invocation to the three deities again in his reign. In Vedic texts which predate these inscriptions by thousands of years, the Vedic gods Mithra and Varuna are frequently mentioned together. In the earliest layer of the Rigveda, Varuna is the guardian of moral law, the ruler over Asuras, one who punishes those who sin without remorse, and who forgives those who err with remorse. He is the Guardian deity of the West, meaning regions west of India. He is mentioned in many Rigvedic hymns, such as 7.86-88, 1.25, 2.27-30, 8.8, 9.73 and others. His relationship with waters, rivers and oceans is mentioned in the Vedas. Vedic poets describe him as an aspect and one of the plural perspectives of the Agni, one of the Primary deities. Further, both have wrathful-gracious aspects in Indian mythology.
The early Achaemenid period contained no representation of Ahura Mazda. The winged symbol with a male figure who was formerly regarded by European scholars as Ahura Mazda has been now speculated to represent the royal xvar?nah, the personification of divine power and royal glory. However, it was customary for every emperor from Cyrus until Darius III to have an empty chariot drawn by white horses as a place for Ahura Mazda to accompany the Persian army on battles. The use of images of Ahura Mazda began in the western satraps of the Achaemenid Empire in the late 5th century BCE. Under Artaxerxes II, the first literary reference as well as a statue of Ahura Mazda was built by a Persian governor of Lydia in 365 BCE.
It is known that the reverence for Ahura Mazda, as well as Anahita and Mithra continued with the same traditions during this period. The worship of Ahura Mazda with symbolic images is noticed, but it stopped within the Sassanid period. Zoroastrian iconoclasm, which can be traced to the end of the Parthian period and the beginning of the Sassanid, eventually put an end to the use of all images of Ahura Mazda in worship. However, Ahura Mazda remained symbolized by a dignified male figure, standing or on horseback which is found in Sassanian investiture.

During the Sassanid Empire, a heretical and divergent form of Zoroastrianism, termed Zurvanism, emerged. It gained adherents throughout the Sassanid Empire, most notably the royal lineage of Sassanian emperors. Under the reign of Shapur I, Zurvanism spread and became a widespread cult. Zurvanism revokes Zoroaster's original message of Ahura Mazda as the uncreated spirit, and the "uncreated creator" of all, and reduces him to a created spirit, one of two twin sons of Zurvan, their father and the primary spirit. Zurvanism also makes Ahura Mazda and Angra Mainyu of equal strength and only contrasting spirits.
Other than Zurvanism, the Sassanian kings demonstrated their devotion to Ahura Mazda in other fashions. Five kings took the name Hormizd and Bahram II created the title of "Ohrmazd-mowbad" which was continued after the fall of the Sassanid Empire and through the Islamic times. All devotional acts in Zoroastrianism originating from the Sassanian period begin with homage to Ahura Mazda. The five G?hs begin with the declaration in Middle Persian, that "Ohrmazd is Lord" and incorporate the Gathic verse "Whom, Mazda hast thou appointed my protector". Zoroastrian prayers are to be said in the presence of light, either in the form of fire or the sun. In the Iranian dialects of Yid?a and Mun, the sun is still called "ormozd".
In 1884, Martin Haug proposed a new interpretation of Yasna 30.3 that subsequently influenced Zoroastrian doctrine to a significant extent. According to Haug's interpretation, the "twin spirits" of 30.3 were Angra Mainyu and Spenta Mainyu, the former being literally the "Destructive Spirit"[n 1] and the latter being the "Bounteous Spirit" (of Ahura Mazda). Further, in Haug's scheme, Angra Mainyu was now not Ahura Mazda's binary opposite, but--like Spenta Mainyu--an emanation of Him. Haug also interpreted the concept of a free will of Yasna 45.9 as an accommodation to explain where Angra Mainyu came from since Ahura Mazda created only good. The free will made it possible for Angra Mainyu to choose to be evil. Although these latter conclusions were not substantiated by Zoroastrian tradition, at the time Haug's interpretation was gratefully accepted by the Parsis of Bombay since it provided a defense against Christian missionary rhetoric,[n 2] particularly the attacks on the Zoroastrian idea of an uncreated Evil that was as uncreated as God was. Following Haug, the Bombay Parsis began to defend themselves in the English-language press, the argument being that Angra Mainyu was not Mazda's binary opposite, but his subordinate, who--as in Zurvanism also--chose to be evil. Consequently, Haug's theories were disseminated as a Parsi interpretation, also in the West, where they appeared to be corroborating Haug. Reinforcing themselves, Haug's ideas came to be iterated so often that they are today almost universally accepted as doctrine.[n 3]
In other religions
Some scholars (Kuiper. IIJ I, 1957; Zimmer. Münchner Studien 1984:187-215) believe that Ahura Mazda originates from *vouruna-mitra, or VedicVaruna (and Mitra). According to William W Malandra both Varuna (in Vedic period) and Ahura Mazda (in old Iranian religion) represented same Indo-Iranian concept of a supreme "wise, all-knowing lord".

In Manichaeism, the name Ohrmazd Bay ("god Ahura Mazda") was used for the primal figure N Qa?m?y?, the "original man" and emanation of the Father of Greatness (in Manicheism called Zurvan) through whom after he sacrificed himself to defend the world of light was consumed by the forces of darkness. Although Ormuzd is freed from the world of darkness his "sons", often called his garments or weapons, remain. His sons, later known as the World Soul, after a series of events will for the most part escape from matter and return again to the world of light where they came from. Manicheans often identified many of Mani's cosmological figures with Zoroastrian ones. This may be in part because Mani was born in the greatly Zoroastrian Parthian Empire.
In SogdianBuddhism, Xwrmzt' (Sogdian was written without a consistent representation of vowels) was the name used in place of Ahura Mazda. Via contacts with Turkic peoples like the Uyghurs, this Sogdian name came to the Mongols, who still name this deity Qormusta Tengri (Also Qormusta or Qormusda) is now a popular enough deity to appear in many contexts that are not explicitly Buddhist.
The pre-Christian Armenians had Aramazd as an important deity in their pantheon of gods. He is thought to be a syncretic deity, a combination of the autochthonous Armenian figures Aram and his son Ara and the Iranian Ahura Mazda. In modern-day Armenia, Aramazd is a male first name.

^For an explanation of the approximation of mainyu as "spirit", see Angra Mainyu.
^Most prominent of these voices was that of the Scottish Presbyterian minister Dr. John Wilson, whose church was next door to the M. F. Cama Athornan Institute, the premier school for Zoroastrian priests. That the opinions of the Zoroastrian priesthood is barely represented in the debates that ensued was to some extent due to the fact that the priesthood spoke Gujarati and not English, but also because they were (at the time) poorly equipped to debate with a classically trained theologian on his footing. Wilson had even taught himself Avestan.
^For a scholastic review of the theological developments in Indian Zoroastrianism, particularly with respect to the devaluation of Angra Mainyu to a position where the (epitome of) pure evil became viewed as a creation of Mazda (and so compromised their figure of pure good), see Maneck 1997
