who was the leader of the gods in babylon

The leader of the gods in Babylon was Marduk. He was the chief god of the city of Babylon and the national god of Babylonia. Marduk was also known as Bel, meaning "Lord." He originally seems to have been a god of thunderstorms and rose to preeminence by conquering the primordial chaos monster Tiamat, after which he became the "lord of the gods of heaven and earth." Marduk was considered the creator of nature and humanity and was thought to control the destiny of kingdoms and individuals. His chief temples were Esagila and Etemenanki in Babylon, where the Babylonian creation myth, Enuma Elish, was celebrated annually. Thus, Marduk was the supreme deity and the leader of the Babylonian pantheon.
