During the reign of the Cassite dynasty, however, the worship of Ramman appears to have gained a stronger foothold.

Several kings of this dynasty have incorporated the name of this deity into their own names, and in an inscription dealing with events that transpired in the reign of one of these kings, Ramman occupies a prominent place.

Immediately after the great triad, Anu, Bel, and Ea, there is enumerated a second, Sin, Shamash, and Ramman, and only then there follows Marduk.[176] More than this, Ramman is introduced for a second time in conjunction with Shamash, as in the hymn of Hammurabi.
The two are appealed to as 'the divine lords of justice.' The conqueror of the Cassites, Nebuchadnezzar I., also holds Ramman in high esteem.
For him, Ramman is the god of battle who in companionship with Ishtar abets the king in his great undertakings.

He addresses Ramman as the great lord of heaven, the lord of subterranean waters and of rain, whose curse is invoked against the one who sets aside the decrees of Nebuchadnezzar or who defaces the monument the king sets up.

While acknowledging the supremacy of Marduk, upon whose appeal he proceeds to Babylonia to rid the country of its oppressors, Nebuchadnezzar nevertheless shows remarkable partiality for Ramman, perhaps as a matter of policy to offset the supposed preference shown by Ramman towards the previous dynasty.
