Henotheistic in the context of "Friedrich Schelling"

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.

Akhenaten (pronounced /ˌækəˈnɑːtən/ listen), also spelled Akhenaton or Echnaton (Ancient Egyptian: ꜣḫ-n-jtn ʾŪḫə-nə-yātəy, pronounced [ˈʔuːχəʔ nə ˈjaːtəj] , meaning 'Effective for the Aten'), was an ancient Egyptian pharaoh reigning c. 1353–1336 or 1351–1334 BC, the tenth ruler of the Eighteenth Dynasty. Originally named Amenhotep IV (Ancient Egyptian: jmn-ḥtp, meaning "Amun is satisfied", Hellenized as Amenophis IV), in the fifth year of his reign he adopted the name "Akhenaten".

As a pharaoh, Akhenaten is noted for abandoning traditional ancient Egyptian religion of polytheism and introducing Atenism, or worship centered around Aten. The views of Egyptologists differ as to whether the religious policy was absolutely monotheistic, or whether it was monolatristic, syncretistic, or henotheistic. This culture shift away from traditional religion was reversed after his death. Akhenaten's monuments were dismantled and hidden, his statues were destroyed, and his name excluded from lists of rulers compiled by later pharaohs. Traditional religious practice was gradually restored, notably under his close successor Tutankhamun, who changed his name from Tutankhaten early in his reign. When, some dozen years later, rulers without clear rights of succession from the Eighteenth Dynasty founded a new dynasty, they discredited Akhenaten and his immediate successors and referred to Akhenaten as "the enemy" or "that criminal" in archival records.

Conceptions of God in classical theist, monotheist, pantheist, and panentheist traditions – or of the supreme deity in henotheistic religions – can extend to various levels of abstraction:

• as a powerful, personal, supernatural being, or as the deification of an esoteric, mystical or philosophical entity or category;
• as the "Ultimate", the summum bonum, the "Absolute Infinite", the "Transcendent", or Existence or Being itself;
• as the ground of being, the monistic substrate, that which we cannot understand; and so on.

The first recordings that survive of monotheistic conceptions of God, borne out of henotheism and (mostly in Eastern religions) monism, are from the Hellenistic period. Of the many objects and entities that religions and other belief systems across the ages have labeled as divine, the one criterion they share is their acknowledgment as divine by a group or groups of human beings.

A supreme deity, supreme god or supreme being is the conception of the sole deity of monotheistic religions or, in polytheistic or henotheistic religions, the paramount deity or supernatural entity which is above all others.

Atenism, also known as the Aten religion, the Amarna religion, and the Amarna heresy, was a religion in ancient Egypt. It was founded by Akhenaten, a pharaoh who ruled the New Kingdom under the Eighteenth Dynasty. The religion is described as monotheistic or monolatristic, although some Egyptologists argue that it was actually henotheistic. Atenism was centered on the cult of Aten, a god depicted as the disc of the Sun. Aten was originally an aspect of Ra, Egypt's traditional solar deity, though he was later asserted by Akhenaten as being the supreme of all deities.

In the 14th century BC, Atenism was Egypt's state religion for around 20 years, and Akhenaten met the worship of other gods with persecution; he closed many traditional temples, instead commissioning the construction of Atenist temples, and also suppressed religious traditionalists. However, subsequent pharaohs toppled the movement in the aftermath of Akhenaten's death, thereby restoring Egyptian civilization's traditional polytheistic religion. Large-scale efforts were then undertaken to remove from Egypt and Egyptian records any presence or mention of Akhenaten, Atenist temples, and assertions of a uniquely supreme god.

Demonization or demonisation is the reinterpretation of polytheistic deities as evil, lying demons by other religions, generally by the monotheistic and henotheistic ones. The term has since been expanded to refer to any characterization of individuals, groups, or political bodies as evil.
