Akkad
According to the Sumerian king list, Akkad (Agade) was built by Sargon of Akkad, 23th century BC, and is often called the first empire in history. Even so, it is known from older cuneiform writings that the city was already there before Sargon, in the time of the kings of Uruk. According to the Bible (Genesis 10:10), it was one of the cities started by Nimrod. Also, in the earliest records, when Mesopotamian kings started calling themselves "lord of the four quarters" around Sumer, these were listed as: Martu, Shubar, Elam, and Uri-ki.
