Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
Brașov
The oldest traces of human activity and settlements in Brașov date back to the Neolithic age (about 9500 BCE). Archaeologists working from the last half of the 19th century discovered continuous traces of human settlements in areas situated in Brașov: Valea Cetății, Pietrele lui Solomon, Șprenghi, Tâmpa, Dealul Melcilor, and Noua. The first three locations show traces of Dacian citadels; Șprenghi Hill housed a Roman-style construction. The last two locations had their names applied to Bronze Age cultures — "Schneckenberg" ("Hill of the Snails"; Early Bronze Age) and "Noua" ("The New"; Late Bronze Age).
