Constanta County has an ancient historical tradition whose origins of human dwelling are manifested with the process of anthropogenesis (Paleolithic Age). The Bronze Age and the Iron Age reveal the thriving of the Thracian civilization and then the Geto-Dacian civilization, which is the basic population of Dobrogea and Constanta County for a long time. Starting with sec. VII before Christ, on the western shore of the Black Sea are installed the first Greek colonies: Histria, Tomis and Calatis, all situated on the territory of Constanta County - Greek civilization, entering a continuous and fruitful dialogue with the native population of the Geto-Dacians. At the end of the 1st century, i. Dobrogea and Constanta County have passed under the rule of the Roman Empire - a civilization that lasted 630 years. The influence of Rome and later of the Roman-Byzantine era was felt and contributed to the formation of the Romanian people and the Roman language. The medieval period is manifested by the evolution of the Romanian civilization initially integrated to the Romanian Country until the end of the reign of Mircea the Elder, after which Dobrogea and Constanta County, for 400 years, was under Ottoman administration. Numerous architectural monuments also reveal this medieval-era print. After the independence war of 1877, Dobrogea returned to the motherland - the Romanian national state - and the Treaty of Berlin (1878) consecrated the conquest of Romania's state independence. Undoubtedly, the history of Constanta County is indissolubly linked to that of the ancient city of Tomis (today Constanta).
