All dates from this long ago should be regarded as either approximate or conjectural; there are no absolute dates for this time period.

c. 2150–2040 BC – The First Intermediate Period of Egypt, a period of decline in Egyptian central power.^[1]
c. 2112–2004 BC – The Third Dynasty of Ur.^[2] The Ziggurat of Ur is built. Administrative power in Ur is pushed far, with an Ensi, an appointed civil servant, at the head of the constituencies. A meticulous and finicky bureaucracy manages, counts and controls the whole administration, which is as much concerned with the economy as with war or the service of the gods. The weight of such an administration arguably contributes to the collapse of the empire. Finally, the Elamites sack Ur and the third dynasty comes to an end.^[3]
