History of the world
Whether in prehistoric or historic times, people always needed to be near reliable sources of potable water. Settlements developed on river banks as early as 3000 BCE in Mesopotamia, on the banks of Egypt's Nile River, in the Indus River valley, and along China's rivers. As farming developed, grain agriculture became more sophisticated and prompted a division of labour to store food between growing seasons. Labour divisions led to the rise of a leisured upper class and the development of cities, which provided the foundation for civilization. The growing complexity of human societies necessitated systems of accounting and writing.
History of Cluj-Napoca
The oldest human settlement near Cluj dates from the Neolithic Age. It was discovered at Gura Baciului, near Suceagu, in the valley of a tributary of the Nadăș river and nearby the Hoia Forest. The settlement dates back to 6000–5500 BCE, making it the oldest discovered settlement in Transylvania. The archaeological discovery connects it to the Starčevo–Kőrös–Criş culture, and more settlements like these have been discovered since: a tomb from this same culture was discovered in the Mănăștur district, and a similar settlement was discovered on the Strada Memorandumului.
