Marduk

Marduk (Sumerian spelling in Akkadian: AMAR.UTU "solar calf"; Biblical: Merodach מְרֹדַךְ) was the Babylonian name of a late-generation god from ancient Mesopotamia and patron deity of the city of Babylon, who, when Babylon permanently became the political center of the Euphrates valley in the time of Hammurabi (18th century BC), started to slowly rise to the position of the head of the Babylonian pantheon, a position he fully acquired by the second half of the second millennium BC.
