Overview
Sumerian religion is the oldest religious tradition known from written sources, practiced in the city-states of southern Mesopotamia from shortly after 3000 BCE until Sumerian ceased to be a living language around 1900 BCE, with each city centered on the temple of its own patron god. Sumerian myths and ritual forms passed almost intact to the Akkadians, Babylonians and Assyrians, who preserved them in cuneiform for another two millennia.[1–2, 7–8]
History

City-states around the temple c. 3300–2334 BCE
Sumerian speakers were established in southern Mesopotamia by about 3300 BCE, and shortly after 3000 BCE Mesopotamia's recorded history begins; by the third millennium the land held at least a dozen walled city-states, each built around the temple of its own patron god.[1–2]
Akkad and the Third Dynasty of Ur c. 2334–2004 BCE
Sargon of Akkad conquered the Sumerian city-states and built the first Mesopotamian empire; after his dynasty's fall, the Third Dynasty of Ur briefly reunified the south, and it was in this age that most surviving Sumerian literature took the written form in which it survives.[9]
Absorbed into a wider tradition c. 2000–1900 BCE
Sumer's political unity ended when Ur fell around 2000 BCE, and Sumerian ceased to be a living spoken language soon after, even as Sumerian religious vocabulary and temple culture carried on among Akkadian-speaking successors.[7–8]

Practice

Praise and lament
Professional singers, the encomiast, sang hymns of praise, while a separate class, the elegist, sang laments over destroyed temples and dying fertility gods.[10]
Scripture
The Epic of Gilgamesh
Separate Sumerian poems about the legendary king Gilgamesh of Uruk circulated before being woven, centuries later, into the longer Akkadian epic.[11]

How we know
Knowledge of Sumerian religion rests almost entirely on archaeology and cuneiform tablets excavated since the nineteenth century; most literary copies come from Old Babylonian scribal schools centuries after the texts were first composed.[12]
Common misconceptions
Myth Sumerian ziggurats were tombs, like Egyptian pyramids.
Fact A ziggurat was a stepped temple tower topped by a shrine; kings and commoners were normally buried elsewhere, not inside the ziggurat itself.[6]
