Enmebaragesi

Enmebaragesi (Sumerian: 𒂗𒈨𒁈𒄄𒋛 Enmebárgisi [EN-ME-BARA2-GI4-SE]; fl. c. 2750 BC) originally Mebarasi (𒈨𒁈𒋛) was the penultimate king of the first dynasty of Kish and is recorded as having reigned 900 years in the Sumerian King List. Like his son and successor Aga, he reigned during a period when Kish had hegemony over Sumer.a Enmebaragesi signals a momentous documentary leap from mytho-history to history, since he is the earliest ruler on the king list whose name is attested directly from archaeology.
