The [[Ubaid period]] (c. 6500–3800 BC) began in [[Mesopotamia]], its name derived from [[Tell al-'Ubaid]] where the first significant excavation took place.<ref>Carter, Robert A. and Philip, Graham  ''[http://oi.uchicago.edu/research/pubs/catalog/saoc/saoc63.html Beyond the Ubaid: Transformation and Integration in the Late Prehistoric Societies of the Middle East (Studies in Ancient Oriental Civilization, Number 63)] {{Webarchive|url=https://web.archive.org/web/20131115070526/http://oi.uchicago.edu/research/pubs/catalog/saoc/saoc63.html |date=15 November 2013 }}'' The Oriental Institute of the University of Chicago (2010) {{ISBN|978-1-885923-66-0}} p. 2; "Radiometric data suggest that the whole Southern Mesopotamian Ubaid period, including Ubaid 0 and 5, is of immense duration, spanning nearly three millennia from about 6500 to 3800 B.C."</ref><ref>Hall, Henry R. and Woolley, C.

By the end of this millennium, [[Jericho]] had become a large agricultural settlement with some eight to ten acres within its walls. [[Kathleen Kenyon]] reckoned that it was home to about three thousand people. Construction was done using stone implements to mould clay into bricks. The main crop was wheat.<ref>Bronowski, p. 70.</ref>
