Ancient Iranian religion in the context of "Ancient history of Afghanistan"

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.

Zarathushtra Spitama, more commonly known as Zoroaster or Zarathustra, was an Iranian religious reformer who challenged the tenets of the contemporary Ancient Iranian religion, becoming the spiritual founder of Zoroastrianism. In the oldest Zoroastrian scriptures, the Gathas, which he is traditionally believed to have authored, he is described as a preacher and a poet-prophet. Some have claimed, with much scholarly controversy, to find his influence in Heraclitus, Plato, Pythagoras, and, perhaps less controversially, in the Abrahamic religions, including Judaism, Christianity, and Islam, particularly through concepts of cosmic dualism and personal morality.

He spoke an Eastern Iranian language, named Avestan by scholars after the corpus of Zoroastrian religious texts written in that language. Based on this, it is tentative to place his homeland somewhere in the eastern regions of Greater Iran (perhaps in modern-day Afghanistan or Tajikistan), but his exact birthplace is uncertain. His life is traditionally dated to sometime around the 7th and 6th centuries BC; though most scholars, using linguistic and socio-cultural evidence, suggest a dating to somewhere in the second millennium BC.

The religions of the ancient Near East were mostly polytheistic, with some examples of monolatry (for example, Yahwism and Atenism). Some scholars believe that the similarities between these religions indicate that the religions are related, a belief known as patternism.

Many religions of the ancient near East and their offshoots can be traced to Proto-Semitic religion. Other religions in the ancient Near East include the ancient Egyptian religion, the Luwian and Hittite religions of Asia Minor and the Sumerian religion of ancient Mesopotamia. Offshoots of Proto-Semitic religion include Canaanite religion and Arabian religion. Judaism is a development of Canaanite religion, both Indo-European and Semitic religions influenced the ancient Greek religion, and Zoroastrianism was a product of ancient Indo-Iranian religion primarily the ancient Iranian religion. In turn these religious traditions strongly influenced the later monotheistic religions of Christianity, Mandaeism, Druzism, Gnosticism, Islam, and Manicheanism, which inherited their monotheism from Judaism and Zoroastrianism.

Yazidis, also spelled Yezidis (/jəˈziːdiz/ ; Êzidî), are a Kurdish-speaking endogamous religious group indigenous to Kurdistan, a geographical region in Western Asia that includes parts of Iraq, Syria, Turkey, and Iran, with small numbers living in Armenia and Georgia. The majority of Yazidis remaining in the Middle East today live in Iraq, primarily in the governorates of Nineveh and Duhok.

There is a disagreement among scholars and in Yazidi circles on whether the Yazidi people are a distinct ethnoreligious group or a religious sub-group of the Kurds, an Iranic ethnic group. Yazidism is the ethnic religion of the Yazidi people. It is monotheistic in nature and syncretic. Having its origin from Adawiyya Sufi order, which blended Sufi Sunni Islam, a local Kurdish veneration of Yazid ibn Mu'awiya and Umayyad dynasty, and local Kurdish peasant belief of pre-Zoroastrian Iranic faith. By the 15th century, Yazidism developed into a distinct religion separate from Islam.

Yazidism, also known as Sharfadin, is a monotheistic syncretic ethnic religion its origin from Adawiyya Sufi order, which blended Sufi Sunni Islam, a local Kurdish veneration of Yazid ibn Mu'awiya and Umayyad dynasty, and local Kurdish peasant belief of pre-Zoroastrian Iranic faith. Its followers, called Yazidis, are a Kurdish-speaking community.

Yazidism includes elements of ancient Iranian religions, as well as elements of Judaism, Church of the East, and Islam. Yazidism is based on belief in one God who created the world and entrusted it into the care of seven Holy Beings, known as Angels. Preeminent among these Angels is Tawûsî Melek (lit. 'Peacock Angel', also spelled as Melek Taûs), who is the leader of the Angels and who has authority over the world. The religion of the Yazidis is a highly syncretistic one: Sufi influence and imagery can be seen in their religious vocabulary, especially in the terminology of their esoteric literature, but much of the mythology is non-Islamic, and their cosmogonies apparently have many points in common with those of ancient Iranian religions.

Kurdish Christians refers to Kurds who follow Christianity. Some Kurds had historically followed Christianity and remained Christian when most Kurds were converted to Islam, however, the majority of modern Kurdish Christians are converts. Historically, Kurdish converts to Christianity came from diverse backgrounds, including Ancient Iranian religion, Zoroastrianism, Islam, and Yazidism.
