Avestan period in the context of "Zoroastrian religion"

Zoroastrianism, also called Mazdayasna or Behdin, is an Iranian religion centred on the Avesta and the teachings of Zarathushtra Spitama, who is more commonly referred to by the Greek translation, Zoroaster (Greek: Ζωροάστρις Zōroastris). Among the world's oldest organized faiths, its adherents exalt an uncreated, benevolent, and all-wise deity known as Ahura Mazda (𐬀𐬵𐬎𐬭𐬀⸱𐬨𐬀𐬰𐬛𐬁), who is hailed as the supreme being of the universe. Opposed to Ahura Mazda is Angra Mainyu (𐬀𐬢𐬭𐬀⸱𐬨𐬀𐬌𐬥𐬌𐬌𐬎), who is personified as a destructive spirit and the adversary of all things that are good. As such, the Zoroastrian religion combines a dualistic cosmology of good and evil with an eschatological outlook predicting the ultimate triumph of Ahura Mazda over evil. Opinions vary among scholars as to whether Zoroastrianism is monotheistic, polytheistic, henotheistic, or a combination of all three. Zoroastrianism shaped Iranian culture and history, while scholars differ on whether it significantly influenced ancient Western philosophy and the Abrahamic religions, or gradually reconciled with other religions and traditions, such as Christianity and Islam.

Originating from Zoroaster's reforms of the ancient Iranian religion, Zoroastrianism began during the Avestan period (possibly as early as the 2nd millennium BCE), but was first recorded in the mid-6th century BCE. For the following millennium, it was the official religion of successive Iranian polities, beginning with the Achaemenid Empire, which formalized and institutionalized many of its tenets and rituals, and ending with the Sasanian Empire, which revitalized the faith and standardized its teachings. In the 7th century CE, the rise of Islam and the ensuing Muslim conquest of Iran marked the beginning of the decline of Zoroastrianism. The persecution of Zoroastrians by the early Muslims in the nascent Rashidun Caliphate prompted much of the community to migrate to the Indian subcontinent, where they were granted asylum and became the progenitors of today's Parsis. Once numbering in the millions, the world's total Zoroastrian population is estimated to comprise between 110,000 and 120,000 people, with most of them residing either in India (50,000–60,000), in Iran (15,000–25,000), or in North America (22,000). The religion is thought to be declining due to restrictions on conversion, strict endogamy, and low birth rates.

Avestan (/əˈvɛstən/ ə-VESS-tən) is the liturgical language of Zoroastrianism. It belongs to the Iranian branch of the Indo-European language family and was originally spoken during the Avestan period (c. 1500 – 400 BCE) by the Iranians living in eastern Greater Iran as evidenced from names in Avestan geography.

After Avestan became extinct, its religious texts were transmitted orally, then collected and put into writing during the Sasanian period (c. 400 – 500 CE). The extant material falls into two groups: Old Avestan (c. 1500 – 900 BCE) and Younger Avestan (c. 900 – 400 BCE). The immediate ancestor of Old Avestan was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language. As such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language.

The Avesta is the text corpus of religious literature of Zoroastrianism. All its texts are composed in the Avestan language and written in the Avestan alphabet. Modern editions of the Avesta are based on the various manuscripts that have survived in India and Iran.

The individual texts of the Avesta were originally oral compositions. They were composed over a long period of several centuries during the Avestan period (possibly ranging from 15th century BCE – 4th century BCE). The written transmission began much later during the Sasanian era (224 to 651 CE), with the creation of the Avestan alphabet. The resulting texts were then compiled into the multi-volume edition of the Sasanian Avesta. This edition was lost sometime after the 10th century CE, and only a small portion of it has survived, scattered across a number of individual manuscript traditions. The oldest surviving fragment of such a manuscript dates to 1323 CE.

Herat, also known as Harat or Hirat, and historically known as Hira, Harew, Haraiva, Areion, and Horeiva, is an oasis city and the third-largest city in Afghanistan. In 2020, it had an estimated population of 574,276. It is the capital of Herat Province, situated south of the Paropamisus Mountains (Selseleh-ye Safēd Kōh) in the fertile valley of the Hari River in the western part of the country. An ancient civilization on the Silk Road between West Asia, Central Asia, and South Asia, it is a regional hub in the country's west.

Herat dates back to Avestan times and was traditionally known for its wine. The city has a number of historic sites, including the Herat Citadel and the Musalla Complex. During the Middle Ages, Herat became one of the important cities of Khorasan, as it was known as the Pearl of Khorasan. After its conquest by Tamerlane, the city became an important center of intellectual and artistic life in the Islamic world. Under the rule of Shah Rukh, the city served as the focal point of the Timurid Renaissance, whose glory is thought to have matched Florence of the Italian Renaissance as the center of a cultural rebirth. After the fall of the Timurid Empire, Herat has been governed by various Afghan rulers since the early 18th century. In 1716, the Abdali Afghans inhabiting the city revolted and formed their own Sultanate, the Sadozai Sultanate of Herat. They were conquered by the Afsharid Persia in 1732.

Avestan geography refers to the investigation of place names in the Avesta and the attempt to connect them to real-world geographical sites. It is connected to but different from the cosmogony expressed in the Avesta, where place names primarily refer to mythical events or a cosmological order.

Identifying such connections is important for localizing the people of the Avesta and is therefore crucial for understanding the early history of Zoroastrianism and the Iranians. Sources for such geographical references are exclusively found in the younger Avestan portion of the text, in particular in the Vendidad and several of the Yashts. The identification of these Avestan place names with real locations is often supported by comparisons with references made in later Iranian sources.

The Yaz culture (named after the type site Yaz-Tappe, Yaz Tepe, or Yaz Depe, near Baýramaly, Turkmenistan) was an early Iron Age culture of Margiana, Bactria and Sogdia (c. 1500–500 BC, or c. 1500–330 BC). It emerges at the top of late Bronze Age sites (BMAC), sometimes as mud-brick platforms and sizeable houses associated with irrigation systems. Ceramics were mostly hand-made, but there was increasing use of wheel-thrown ware. Bronze and iron arrowheads, iron sickles and carpet knives are among other artifacts that have been found.

With the farming citadels and absence of burials it has been regarded as a likely archaeological reflection of early East Iranian culture as described in the Avesta. So far, no burials related to the culture have been found, and this is taken as possible evidence of the Zoroastrian practice of exposure or sky burial.

Turan (Avestan: Tūiriiānəm; Middle Persian: Tūrān; Persian: توران, romanized: Turân, pronounced [tʰuːˈɾɒːn], lit. 'The Land of Tur') is a historical region in Central Asia. The term is of Iranian origin and may refer to a particular prehistoric human settlement, a historic geographical region, or a culture. The original Turanians were an Iranian tribe of the Avestan age.
