Mesopotamia produced one of the best-known ancient civilizations, with a literate, urban culture and highly-developed political institutions. Harriet Crawford reviews the extraordinary social and technological developments in the region over a period of two millennia (from 3800 to 2000 BC) in this fully revised and expanded edition of her classic text. Drawing on the most up-to-date historical and archaeological sources, she describes the physical environment and covers architecture, trade and industry, the development of writing, and changes in social and political structures.
