Histria was founded as a colony of the Ionian city of Miletus towards the end of the 7th century BC. It got its name from the Danube, whose lower reaches the Greeks called Istros and which flows into the Black Sea not far away from Histria.
After the Persian Wars, Histria experienced a flourishing period in the 5th century BC. In the 4th century B.C. it came under Scythian influence, and since Alexander the Great under Macedonian influence. From the 1st century B.C. Histria belonged to the Roman sphere of influence, interrupted by a brief rule of the Dacian king Burebista over the city.
The decline of the town began with a plundering by the Goths in the middle of the 3rd century AD, but it continued to exist, since Diocletian as part of the province of Scythia, until the early Byzantine period. After being destroyed by Avars and Slavs, Histria was abandoned at the beginning of the 7th century AD.
Since 1914, Histria has been the site of repeated archaeological excavations by Romanian researchers, who uncovered parts of the Byzantine and Roman buildings and penetrated to the earliest Greek layers, dating back to the 7th century BC.
