The prehistoric presence of humanity is confirmed in numerous locations throughout Dobrogea : in the caves of "Adam" and "Izvor" in the valley of Casimcea, and in the villages of Mamaia, Cernavoda, Medgidia, Ovidiu, Nazarcea, Topalu and others...

As archaeological research has shown, during the Neolithic, these communities created very evolved civilizations.
In the second and first millennia BC, the Gete and Dace tribes were born from cultural and ethnic intermingling in the Carpathian-Danubian region.
During the seventh and sixth century BC, the coast of the Black Sea saw a rapid development as the Greek colonists founded the cities of Tyras, Argamum, Histria, Tomis, Callatis and others.

During seven centuries, Dobrogrea was integrated into the Roman world. In 28 AD the area passed to the control of the king of the Odrides, an agent of Rome, and then the Moésie province annexed the region in 46 AD.
In 602 AD, the Roman domination of the Danube frontier caved in under the pressure of the Slaves, yet maintained relations with the Byzantine Empire until the arrival of the Buglers in 680. During the re-occupation of the region by Byzantium in the Tenth Century the area experienced diverse political systems under the rule of various local chiefdoms.
In the fourteenth century, Dobrotita, son of Dobrotici, united all the smaller entities recognized by the Byzantine Empire under one State that would later share in the "Tara Româneasca".
From the fifteenth to the seventeenth century the expansion of the Ottoman Empire brought Dobrogea under the flag of the Crescent Moon.
After the War of Independence in 1877-1878, in accord with the Berlin Treaty, the region between the Danube and the Black Sea became the modern State of Romania.
