In Mesopotamia, one of the world's earliest civilizations, the emergence of writing was closely tied to the development of urban life, particularly in cities such as Uruk and Babylon. This writing began in about 3200 BCE, initially comprising pictographs that evolved into a more complex system of cuneiform signs, used for record-keeping in administration and trade. As cities developed, so did the complexity of their economies and social structures, requiring a system for documentation and communication. Scribes, who were trained in this craft, played a crucial role in facilitating trade, governance, and cultural development. The ability to document transactions and legal agreements allowed for greater organization within these societies. The section emphasizes that writing allowed for the preservation of knowledge across generations, contributing to the cultural legacy of civilizations and affecting practices such as record-keeping, literature, and government administration.
