Ashur (god)
Ashur, Ashshur, also spelled Ašur, Aššur (Sumerian:  AN.ŠAR₂, Assyrian cuneiform:  ,  ) is the national god of the ancient Assyrians.

History
Ashur was the city god of the eponymous Assur, and was frequently interchanged in Old Assyrian texts. Since the city of Assur was situated upon a natural hill, Ashur may have been the deified hill, and subsequent Old Assyrian names that invoke Ashur relationship with mountains do suggest that he was originally a mountain god. Several things separate Ashur from the gods of Southern Mesopotamia, such as the fact that he did not originally have a family or any attributes, being solely connected to his city. A bull frequently appears in Old Assyrian seals, appearing to be worshipped, suggesting that the bull was either the symbol of Ashur or was Ashur himself. The rulers of Assur were only called the "governors" (išši'akum) of Assur, reserving the title of king for the god. A similar system was also attested in Eshnunna, with the human king as the governor and Tishpak taking on titles usually ascribed to kings. As a general rule, Ashur was not worshiped outside of the city of Assur, except in some of the Assyrian trading colonies (karum).

When Shamshi-Adad I captured Assur, he brought with him an increased level of southern influences. Shamshi-Adad renovated the temple of the god Ashur and called it Enlil's temple, equating Ashur with Enlil. This equation would become significant from the Middle Assyrian Period onwards, and Ashur would absorb Enlil's family, including his wife Ninlil (Mullissu) and his son Ninurta 

During the Middle Assyrian Period, Tukulti-Ninurta I made the unprecedented move regarding the cult of Ashur. Kar-Tukulti-Ninurta, a new royal residence north-east of Assur named after the king himself, would contain a new temple dedicated to Ashur. The city was largely abandoned after his death. Assur would remain the only cult center of the god Ashur until the fall of the Assyrian state.

With the development of the territorial state of Assyria, Ashur was also transformed from a local god to a national one. Ashur was conceptualized as the father of the gods. He was essential to Assyrian imperial ideology, with the King, the representative of Ashur, being expected to fulfill the divine mandate and expand the lands of Assyria as reflecting Ashur's universal rule. The close link between the Assyrian king and the god Ashur was reflected in the coronation ceremony which was performed in the temple of the god in the city of Assur, and the King was said to be the mirror image of Ashur.

Starting from the reign of Sargon II, Ashur was occasionally written as Anshar, the Primordial god in the Babylonian Enuma Elish that gave birth to Anu along with Kishar. After Sennacherib's destruction of Babylon in 689 BCE, Assyrian scribes fashioned a new version of Enuma Elish that exalted Ashur instead of Marduk. Ashur continued to be revered as Anshar in Neo-Babylonian Uruk after the collapse of the Assyrian Empire, where a temple to Ashur was built under the name of Anshar, breaking the tradition that Ashur's only cult place would be the city of Assur.

Representation and symbolism

In the Old Assyrian Period, many seals included a worshiped bull, indicating that it was either the symbol of Ashur or depicted Ashur himself. The Neo-Assyrian winged disk is also seen as a symbol for Ashur, although reservations exist, with some arguing that it represents Shamash instead. 

Ashur is attested in theophoric names starting from the Old Assyrian period down to Neo- and Late Babylonian periods. Considering that Ashur was a quintessential Assyrian god, this may be used as an ethnic marker. Ashur is also attested in theophoric names in Hatran Aramaic.
