Historians have also discovered traces of habitation in the Dacian period, during the last centuries B.C. The sites of Straulesti, Popesti-Novaci or Crasani etc. are still there in the archaeologists' academic reports and in the nightmares of high-school students who prepare their graduation exams.

A noteworthy detail are the treasures discovered this century on the site of the city: in 1931, at Fundeni, urns copied after Greek originals were dug up; in 1938, near Herastrau, jewellery and silver coins from the 2^nd century B.C. copied after Greek tetradrachmas were found; the same holds true for subsequent discoveries of treasures in Colentina, Bragadiru or Popesti-Leordeni - all copies of Greek coins from the 4^th or 3^rd centuries B.C. or of Roman coins. Those who marvel today at the wealth of Exchange Offices on the boulevards of Bucharest will understand now that their ancestors were as cosmopolitan as they are in point of financial passion; one could even argue that the fake dollars to be found on today's market are themselves part of some kind of tradition.

The Bucharest area was also inhabited in the first centuries A.D., even if evidence of important habitats is not attested; as was the case with the whole Romanian territory, Bucharest proto-inhabitants pulled through after the centuries of migration, enriching their genetic endowment yet preserving ascendance thanks to their Latin origin. Slavic and Romanian cohabitation resulted in several Slavic etymons, for instance the name of the river Dimbovita, which is probably a reminder of the river-side landscape, one covered by thick oak forests that surrounded the whole city (dimb - Slavic for oak), while the name of the river Ialomita comes from ialov (Slavic for deserted area), as it ran across an area of untilled land. However, strictly Romanian toponyms outnumber these influences; most of them end in -eni or -esti, a clear reference to names of landowners or rulers of the epoch, which could ultimately indicate that the Romanians have had from the very beginning an acute sense of ownership.
