فترة العبيد
During the Ubaid Period (5000–4000 BC), the movement towards urbanization began. "Agriculture and animal husbandry [domestication] were widely practiced in sedentary communities". There were also tribes that practiced domesticating animals as far north as Turkey, and as far south as the Zagros Mountains. The Ubaid period in the south was associated with intensive irrigated hydraulic agriculture, and the use of the plough, both introduced from the north, possibly through the earlier Choga Mami, Hadji Muhammed and Samarra cultures.
