Concept
Ubaid period
Summary
The Ubaid period (c. 5500–3700 BC) is a prehistoric period of Mesopotamia. The name derives from Tell al-'Ubaid where the earliest large excavation of Ubaid period material was conducted initially in 1919 by Henry Hall and later by Leonard Woolley.
In South Mesopotamia the period is the earliest known period on the alluvial plain although it is likely earlier periods exist obscured under the alluvium. In the south it has a very long duration between about 5500 and 3800 BC when it is replaced by the Uruk period.
In Northern Mesopotamia the period runs only between about 5300 and 4300 BC. It is preceded by the Halaf period and the Halaf-Ubaid Transitional period and succeeded by the Late Chalcolithic period.
The term "Ubaid period" was coined at a conference in Baghdad in 1930, where at the same time the Jemdet Nasr and Uruk periods were defined.
The Ubaid period is divided into four principal phases:
Ubaid 0, sometimes called Oueili, (5500–5400 BC), an early Ubaid phase first excavated at Tell el-'Oueili.
Ubaid 1, sometimes called Eridu corresponding to the city Eridu, (5400–4700 BC), a phase limited to the extreme south of Iraq, on what was then the shores of the Persian Gulf. This phase, showing clear connection to the Samarra culture to the north, saw the establishment of the first permanent settlement south of the 5 inch rainfall isohyet. These people pioneered the growing of grains in the extreme conditions of aridity, thanks to the high water tables of Southern Iraq.
Ubaid 2 (4800–4500 BC). At that time, Hadji Muhammed style ceramics was produced. This period also saw the development of extensive canal networks near major settlements. Irrigation agriculture, which seems to have developed first at Choga Mami (4700–4600 BC) and rapidly spread elsewhere, form the first required collective effort and centralised coordination of labour in Mesopotamia.
Ubaid 3: Tell al‐Ubaid style ceramics. Traditionally, this ceramic period was dated 5300–4700 BC.
