Chalcolithic

In 5000 BC, Nineveh transitioned from a Halaf village to an Ubaid village. During the Late Chalcolithic period Nineveh was part one of the few Ubaid villages in Upper Mesopotamia which became a proto-city. Others include Ugarit, Brak, Hamoukar, Arbela, Alep, and regionally Susa, Eridu, Nippur. During the period between 4500 and 4000 BC it grew to 40 hectares in size.

The greater Nineveh area is notable in the diffusion of metal technology across the near east as the first location outside of Anatolia to smelt copper. Tell Arpachiyah has the oldest copper smelting remains, and Tepe Gawa has the oldest metal work. The copper came from the mines at Ergani.
