Short answers, pulled from the story.
The Akkadian Empire, also called the Kingdom of Akkad or Agade, was an ancient kingdom in Mesopotamia established around 2334 BCE and generally dated to 2334 to 2154 BC under the middle chronology. It is sometimes regarded as the first empire in world history, succeeding the city-states of Sumer.
Sargon of Akkad founded the Akkadian Empire after defeating the Sumerian king Lugal-zage-si at the Battle of Uruk. The Sumerian King List records him as the son of a gardener, and he began his career as a cupbearer to Ur-Zababa, a king of Kish.
The Akkadian Empire collapsed from a combination of internal unrest and severe environmental stress, including a major drought associated with the 4.2 kiloyear climate event that caused crop failures, famine, and population displacement. An invasion by the Gutians followed, and the empire likely fell in the 22nd century BC, within 180 years of its founding.
Naram-Sin was Sargon's grandson, ruling about 2254 to 2218 BC, who took the title King of the Four Quarters and declared himself a living god of Agade. He recorded the conquest of Ebla, marched against Magan and captured its king Mandannu, and built a royal residence at Tell Brak.
Enheduanna was the daughter of Sargon and high priestess of the moon god at Ur, and she is the first poet in history whose name is known. Living around 2285 to 2250 BC, she wrote hymns to the goddess Inanna, including the Exaltation of Inanna and the Temple Hymns.
The capital city of Akkad, also called Agade, has not yet been identified on the ground despite much speculation. Because the capital remains unlocated, archaeological remains of the empire are found mainly at provincial cities where regional governors were installed, such as Adab, Mari, Nuzi, and Tell Brak.
