The document summarizes the origins of cities from early hunter-gatherer societies to the emergence of permanent agricultural settlements. As the last ice age ended, some 10,000 years ago, people in the Fertile Crescent region began cultivating crops and domesticating animals, leading to settled agricultural villages. This sedentary lifestyle allowed for population growth and surplus food production. Some villages grew into early cities as divisions of labor emerged, populations concentrated, and formal institutions and defenses developed to manage communal resources and protect settlements, marking the beginnings of urbanization in places like Mesopotamia, Egypt, Anatolia and the Levant.
