Overview
Babylonian and Assyrian religion carried on the religious tradition of Sumer among Mesopotamia's later Semitic-speaking populations, as Marduk of Babylon and Ashur of Assyria each rose to head their own state's pantheon. Marduk's rise is told in the Enuma Elish, recited yearly at Babylon's Akitu festival, while much of what survives of this tradition comes down through the library the Assyrian king Ashurbanipal assembled at Nineveh.[2–7]
History

From Sumer to Babylon and Assyria c. 2000–1750 BCE
After Sumerian political unity ended around 2000 BCE, Babylon in the south and Ashur in the north emerged as successor states inheriting Sumerian religion largely intact, and Babylon's king Hammurabi built the city into a lasting power, his law code showing him before the sun god Shamash.[6, 8]
Neo-Babylonian height and the end of native rule 626 BCE – 1st century CE
Nebuchadnezzar II rebuilt Babylon and its temples at the height of Neo-Babylonian power before Persia's Cyrus took the city in 539 BCE, after which Mesopotamia passed through Achaemenid, Seleucid and Parthian rule into the early centuries CE.[1, 9]

Practice

Omens and scholarship
Priests and scribes compiled large collections of omen texts, treating unusual events as divine messages; this scholarly activity is attested in the cuneiform archives of cities such as Ashur and Nineveh.[10]
Scripture
Enuma Elish · Enūma Eliš
attested by the 12th century BCE
Babylon's creation epic names Marduk supreme among the gods after his defeat of the chaos-monster Tiamat.[4]
Places

Babylon (Esagila and Etemenanki)
IRQ · UNESCO World Heritage, 2019
Babylon's temple complex housed the Esagila, Marduk's sanctuary, beside the ziggurat Etemenanki, likely the model behind the Tower of Babel story.[11]
