3. The Historical Evolution Of The City
What is a city, and how did it become what it is today? The evolution of the city is a fascinating journey through human history.
- Ancient Cities (4000-1000 BCE): The earliest cities emerged in Mesopotamia, Egypt, and the Indus Valley. These cities were centers of agriculture, trade, and religion, characterized by monumental architecture, complex social structures, and specialized labor. Examples include Uruk, Memphis, and Mohenjo-daro.
