This study highlights the social concepts of the ‘night’ of the residents of Mesopotamia, who realized the nature of the universe, constellations, planets, stars, and the sun and the moon and their effect on the daily life. Moreover, they recognized the requirements of the day and the aspects of the night that impacted their life in one way or another. Through the cuneiform regarding day and night, we found that people had their special view concerning ‘night’ in terms of religious and secular dimensions. They had benefited from the appearance of stars and the moon and had related many events – social, religious, or military – to these phenomena. I chose to do this study in relation to ‘night’ due to its importance in the thought and beliefs of people in Mesopotamia. Since the cuneiform texts translated into other foreign languages are the most important resources in this regard, I depended on them in the current study. I divided the research into two parts. In the first part I presented the ‘night’ in language and terminology and the words related to it. The second part of the study includes the information related to the ‘night’ and its connection to social life. The second part is further divided into several sub-sections based on the detail of each theme. The main sources used in the current study are the following: A book by several authors entitled (The Assyrian Dictionary) that includes twenty-one parts presenting thousands of cuneiform texts translated into English. The cuneiform texts explain important information about the civilization of Mesopotamia. Lambert W.G books that include several foreign sources from which I got the information for this study. Ancient Iraqi legislations by Fawzi Rasheed who is specialized in Ancient Iraqi history.
