Ancient Egyptian religion was a complex system of polytheistic beliefs and rituals that formed an integral part of ancient Egyptian culture. It centered on the Egyptians' interactions with many deities believed to be present and in control of the world. About 1,500 deities are known. Rituals such as prayer and offerings were provided to the gods to gain their favor. Formal religious practice centered on the pharaohs, the rulers of Egypt, believed to possess divine powers by virtue of their positions. They acted as intermediaries between their people and the gods, and were obligated to sustain the gods through rituals and offerings so that they could maintain Ma'at, the order of the cosmos, and repel Isfet, which was chaos. The state dedicated enormous resources to religious rituals and to the construction of temples.

Individuals could interact with the gods for their own purposes, appealing for help through prayer or compelling the gods to act through magic. These practices were distinct from, but closely linked with, the formal rituals and institutions. The popular religious tradition grew more prominent over the course of Egyptian history as the status of the pharaoh declined. Egyptian belief in the afterlife and the importance of funerary practices is evident in the great efforts made to ensure the survival of their souls after death – via the provision of tombs, grave goods and offerings to preserve the bodies and spirits of the deceased.

The religion had its roots in Egypt's prehistory and lasted for 3,500 years. The details of religious belief changed over time as the importance of particular gods rose and declined, and their intricate relationships shifted. At various times, certain gods became preeminent over the others, including the sun god Ra, the creator god Amun, and the mother goddess Isis. For a brief period, in the theology promulgated by the pharaoh Akhenaten, a single god, the Aten, replaced the traditional pantheon. Ancient Egyptian religion and mythology left behind many writings and monuments, along with significant influences on ancient and modern cultures. The religion decentralized following the Roman conquest of Egypt in 30 BC and was suppressed during the Christian period. Practices such as mummification halted, and the ancient Egyptian religion was considered to have fully died in the 530s. Following the Arab conquest of Egypt under Amr ibn al-As, Egyptians started to convert to Islam.

History The beginnings of Egyptian religion extend into prehistory, though evidence for them comes only from the sparse and ambiguous archaeological record. Careful burials during the Predynastic period imply that the people of this time believed in some form of an afterlife. At the same time, animals were ritually buried, a practice which may reflect the development of zoomorphic deities like those found in the later religion. The evidence is less clear for gods in human form, and this type of deity may have emerged more slowly than those in animal shape. Each region of Egypt originally had its own patron deity, but it is likely that, as these small communities conquered or absorbed each other, the god of the defeated area was either subsumed into the other god's mythology or entirely replaced by it. This resulted in a complex pantheon in which some deities remained only locally important while others developed more universal significance.

Archaeological data has suggested that the Egyptian religious system had close, cultural affinities with Eastern African populations and arose from an African substratum rather than deriving from the Mesopotamian or Mediterranean regions."A large number of gods go back to prehistoric times. The images of a cow and star goddess (Hathor), the falcon (Horus), and the human-shaped figures of the fertility god (Min) can be traced back to that period. Some rites, such as the "running of the Apil-bull," the "hoeing of the ground," and other fertility and hunting rites (e.g., the hippopotamus hunt) presumably date from early times.. Connections with the religions in southwest Asia cannot be traced with certainty." "It is doubtful whether Osiris can be regarded as equal to Tammuz or Adonis, or whether Hathor is related to the "Great Mother." There are closer relations with northeast African religions. The numerous animal cults (especially bovine cults and panther gods) and details of ritual dresses (animal tails, masks, grass aprons, etc) probably are of African origin. The kinship in particular shows some African elements, such as the king as the head ritualist (i.e., medicine man), the limitations and renewal of the reign (jubilees, regicide), and the position of the king's mother (a matriarchal element). Some of them can be found among the Ethiopians in Napata and Meroe, others among the Prenilotic tribes (Shilluk)."

A number of scholars have associated the Land of Punt with the homeland of Egyptian deities or ancestors, this has been attributed to the fact that Punt was called Ta netjer which translated into the "God's Land"."The most interesting part of the Egyptian knowledge about Sub-Saharan Africa is in relation to Punt and God's Land, or the lands of the gods. These lands had traded with Egypt since 2500 BC or even before. The Egyptians are not known to have had any war with the people of Punt, probably due to the fact that the land was not near enough to wage wars of conquest (kitchen, 1999: 174). These were lands of semi-mythical "horizon dwellers". Egyptians also considered their gods or ancestors to have originated from these lands thought to be in eastern and southern Africa (Whicker, 1990) and hence "God's land" (Kitchen, 1993:592). The records of the last Millennium BC show that Osiris and Isis, the most powerful Egyptian god and goddess, were "Ethiopians"/Black originating from countries in the south of Africa (Leclant, 1997: 157; Kendall, 1997: 171; Waterfield, 1967)."

Predynastic period

The first known depictions of the Egyptian god of fertility Min, appear in the form of monumental statues discovered in an ancient temple at Koptos, dated to the late Naqada II to early Naqada III periods circa 3300 BC, and now displayed in the Ashmolean Museum following their discovery by Flinders Petrie in Koptos at the end of the 19th century. The estimated size of the three known statues ranges from 372 cm to 403 cm. The statues show a bearded man, naked but for a belt and a sash, holding his erect penis. An early form of the character for "Min is inscribed on the side of two of these statues.

On the Koptos monumental statues of Min, generally dated to circa 3300 BC during the late Naqada II- early Naqada III periods, the Min symbol is inscribed, together with marine objects: the "sword" of a sawfish and two shells of the Pterocera species. These symbols seem to corroborate the traditional origin histories of the god, according to which he originated in the fabulous "Land of Punt", in the Eritrean region bordering on the Red Sea.

Early Dynastic period

The Early Dynastic Period began with the unification of Egypt around 3000 BC. This event transformed Egyptian religion, as some deities rose to national importance and the cult of the divine pharaoh became the central focus of religious activity. Horus was identified with the king, and his cult center in the Upper Egyptian city of Nekhen was among the most important religious sites of the period. Another important center was Abydos, where the early rulers built large funerary complexes.

Old and Middle Kingdoms During the Old Kingdom, the priesthoods of the major deities attempted to organize the complicated national pantheon into groups linked by their mythology and worshipped in a single cult center, such as the Ennead of Heliopolis, which linked important deities such as Atum, Ra, Osiris, and Set in a single creation myth. Meanwhile, pyramids, accompanied by large mortuary temple complexes, replaced mastabas as the tombs of pharaohs. In contrast with the great size of the pyramid complexes, temples to gods remained comparatively small, suggesting that official religion in this period emphasized the cult of the divine king more than the direct worship of deities. The funerary rituals and architecture of this time greatly influenced the more elaborate temples and rituals used in worshipping the gods in later periods.

The Ancient Egyptians regarded the sun as a powerful life force. The sun god Ra had been worshipped from the Early Dynastic period (3100–2686 BCE), but it was not until the Old Kingdom (2686–2181 BCE), when Ra became the dominant figure in the Egyptian pantheon, that the Sun Cult took power. Early in the Old Kingdom, Ra grew in influence, and his cult center at Heliopolis became the nation's most important religious site.. By the Fifth Dynasty, Ra was the most prominent god in Egypt and had developed the close links with kingship and the afterlife that he retained for the rest of Egyptian history. Around the same time, Osiris became an important afterlife deity. The Pyramid Texts, first written at this time, reflect the prominence of the solar and Osirian concepts of the afterlife, although they also contain remnants of much older traditions.. The texts are an extremely important source for understanding early Egyptian theology.

Symbols such as the 'winged disc' took on new features. The solar disk with the wings of a hawk was originally the symbol of Horus and associated with his cult in the Delta town of Behdet. The sacred cobras were added on either side of the disc during the Old Kingdom. The winged disc had protective significance and was found on temple ceilings and ceremonial entrances.

In the 22nd century BC, the Old Kingdom collapsed into the disorder of the First Intermediate Period. Eventually, rulers from Thebes reunified the Egyptian nation in the Middle Kingdom (–1650 BC). These Theban pharaohs initially promoted their patron god Montu to national importance, but during the Middle Kingdom, he was eclipsed by the rising popularity of Amun. In this new Egyptian state, personal piety grew more important and was expressed more freely in writing, a trend that continued in the New Kingdom.Callender, Gae, "The Middle Kingdom", in .

New Kingdom The Middle Kingdom crumbled in the Second Intermediate Period (–1550 BC), but the country was again reunited by Theban rulers, who became the first pharaohs of the New Kingdom. Under the new regime, Amun became the supreme state god. He was syncretized with Ra, the long-established patron of kingship and his temple at Karnak in Thebes became Egypt's most important religious center. Amun's elevation was partly due to the great importance of Thebes, but it was also due to the increasingly professional priesthood. Their sophisticated theological discussion produced detailed descriptions of Amun's universal power.

Increased contact with outside peoples in this period led to the adoption of many Near Eastern deities into the pantheon. At the same time, the subjugated Nubians absorbed Egyptian religious beliefs, and in particular, adopted Amun as their own.
