Dacia
is in an area of Central Europe, bounded on the north by the
Carpathians, on the south by the Danube and on the east by the Black
Sea, corresponding to modern Romania and Moldova. With its temperate
climate and varied natural environment, the Dacian territory has been
inhabited since Lower Paleolithic (1.000.000 b.C. - 120.000 b.C.).
At the
beginning of the Neolithic, a relatively stable population can be
found, like the the Hamangia (Tulcea County, 6000 -
5000 b.C.) and Cucuteni (Iaşi County, 4500 b.C. -
3000 b.C.) cultures.
They were supplanted by Indo-European tribes. The Indo-European migrations had been dated between the end of the Neolithic and the late Palaeolithic. At the beginning of the Bronze Age (3300 b.C.) the Indo-European people of the Thracians settled in the Carpathian-Balkan region. In the first half of the first millennium b.C., the Thracian tribes of the Dacians were located in Transylvania and the Getae in Wallachia and Moldavia.
The Greeks first encountered the Getae by means of the
colonies created on the Black Sea shore in 7th century b.C., like
Istros (Histria), Callatis (Mangalia) and Tomi (Constanţa), and they
used their name for the whole population to the north of the Danube.
The Romans first encountered the Dacians, extending this name to cover
all the other tribes on the Dacia province, roughly the present-day
Romania.

In 512 b.C. the Persians leaded by Darius reached the regions of the Danube during the expedition against the Scythians, came in the region from the North of the Black Sea. In 335 b.C. the Macedonians with Alexander the Great conquered Dobruja, but in 300 b.C. and 292 b.C. the Macedonian general Lysimach was defeated by the Getas' king Dromichaites. an invasion in Transylvania by the Celts took place in 300 b.C. too.
One of
the greatest king of Dacia was Burebista, who ruled
between 82 b.C. and 44 b.C.; he succeeded in unifying the Geto-Dacian
tribes in a powerful kingdom. The fortifications and the sanctuary
raised in the area of Sarmizegetusa (in the
national park of Grădiştea Muncelului-Cioclovina, in Southern
Transylvania) prove the development of an advanced civilization. The
Sacred Mountain of Kogaion is identified with the Hill of Gradistea of
the Orastie Mountains area.
In 60 b.C. and 48 b.C. Burebista leaded successful campaigns against the Celts on the West side of the kingdom.
A first contact of the Dacians with the Romans was in 48 b.C., when Burebista took part in the dispote between Caesar and Pompeius offering his military support to Pompeius, who was defeated by Caesar.
After Burebist’s death, the Geto-Dacians kingdom was split into several parts under separate kingdoms, as the Greek cities on the Black Sea and the Celtic tribes no longer accepted the authority of a Dacian state.
