The Anunnaki are the primary deities in ancient Mesopotamian cultures such as Sumerian, Akkadian, Assyrian, and Babylonian. They are associated with fertility and the underworld, where they became judges. Their relation to the Igigi is sometimes unclear, but in one myth the Igigi rebel against working for the Anunnaki. The Anunnaki are mentioned in creation myths and the Epic of Gilgamesh.

1. The Anunnaki are the primary group of deities in ancient
Mesopotamian cultures (i.e. Sumerian, Akkadian, Assyrian, and
Babylonian).
The name means something to the effectof "those of royal blood" or
"princely offspring",and has also been interpreted as "those who
from heavan to earth came".
According to The Oxford Companionto World Mythology, the
Anunnaki:

2. "are the Sumerian deities of the old primordial line; deities of fertility,
associated eventually with the underworld, where they became judges. They
take their name from the old sky god Anu."
Their relation to the group of gods known as the Igigiis not always
clear – at times the names are used synonymously, but in the Atra-
Hasis flood myth the Igigi are the sixth generation of the Gods who
have to work for the Anunnaki, rebelling after 40 days and replaced
by the creation of humans.
The Enuma Elish (also known as The Seven Tablets of Creation) is
the Mesopotamian creation myth whose title is derived from the
opening lines of the piece,`When on High'. In their Epic of Creation, it
is said that there are 300 lgigu of heaven.
When the Anunnaki appear in the Babylonian creation myth, Enuma
Elish (the late version magnifying Marduk), after the creation of
mankind, Marduk divides the Anunnaki and assigns them to their
properstations, in heaven and on the earth.
The Annunaki are mentioned in The Epic of Gilgamesh when
Utnapishtim tells the story of the flood,which shares many similarities
with Noah's deluge in the Bible.
In the Sumerian tale, the seven judges of the underworld are called
the Annunaki, and they set the land aflame as the storm is
approaching.
According to later Assyrian and Babylonian myth, the Anunnaki were
the children of Anu and Ki, brother and sister gods,themselves the
children of Anshar and Kishar (Skypivot and Earthpivot, the Celestial
poles),who in turn were the children of Lahamu and Lahmu ("the
muddy ones"), names given to the gatekeepers of the Abzu (House

3. of Far Waters) temple at Eridu, the site at which the creation was
thought to have occurred.
