Marduk

Marduk, highest god of ancient Babylon. Called “lord of the gods of heaven and earth,” Marduk rose to power by conquering Tiamat, the monster of chaos. Some of Babylon's most elaborate temples were built to worship Marduk, and, as the conquering armies of the empire overran most of the Middle East, worship of Marduk spread to those lands.
