The existence of the area where the present day city of Constanta lies dates back to 500 BC according to inscriptions found of a city called Tomis, a Greek colony which existed at that time.

Due to its strategic location, in the earliest century, the city knew alot of wars and various change of names and take over from varying empires, ranging from the greeks, the Romans, slavs and Avars and Byzanthine.

This also existed in later times, that is in this A.D. century. The city has at one time been included in different province under the various empires after the failure of one empire and subsequent takeover by another.

There was a name change from Tomis to CONSTANTIANA, when the city was under the emperor Constantine the Great. Archealogical evidence showing the earliest usage of the name, "Constantia" dates back in 950.

For quite a time, the city of Constanta successively became part of the Bulgarian Empires, Constanta fell under the Ottoman (present day Turkey) rule around 1419.

A railroad linking Constanta to Cernavoda was opened in 1860. In 1878, Constanta and the rest of Northern Dobrogea (which is the land between the Danube River to the west and Black Sea to the east) was ceded by the Ottoman Empire to Romania after the Romanian War of Independence.

The city became and is still to this day, Romania's main seaport and transit point for much of Romania's exports. In 1916 (during the World War I), Constanta was occupied by briefly by German, Turkish and Bulgarian troops. The Allied troops vacated the city in 1918 after the successful offensive on the Thessaloniki front which knocked Bulgaria out of the war.
