Düzce, the only ancient city of the Western Black Sea, survived to date. It dates back to the Hittite (Eti) civilization that reigned between 1390 and 800. Düzce and its surroundings have been known since the 15th century. Especially in the second volume of Evliya Çelebi's Seyahatname, the bit in Düzce mentions the Salt Market. We can discuss the history of Duzce in four time periods;
Old-time Bithynian Era: In this period, there was almost no Düzce. However, Prusyas (Üskübü) was present. Düzce, on the other hand, was located in a flat and wide plain, in the marshes, east of the settlements of Bitintyalı. ,
Roman and Byzantine Period: Prussia (Üskübü) with the plain in the plain of Düzce, Bitiuyoji Nikomed, the Roman people died by the will. III. After Nikomed's son Filmostan, Bithynia remained under the Roman rule for a while. Düzce 's this time seems to have evolved a little more than the first circuit. The plain of Düzce, which was in the form of a bog in the Bithynian period, was rebuilt by the Romans at the time and was made more suitable for agriculture and began to settle down slowly. After the Romans, this region was dominated by the Byzantines. Here is the development of this circuit, the development of the last time.
The Ottoman Period: During the Ottoman Empire, Konuralp Bey, one of the commanders of Orhan Gazi, freed this place from the domination of the Byzantines and added it to the empire. Düzce 's name to take the name of this period is. Then the first district center is Gümüşabadı. Then the district office called Üskübü. In the center Prusyas (Üskübü) was. Duzce in this period in terms of trade and land Üskübü 'and the first district of the province of Gümüşabadı' in the shade showed. In 1871 the district center was transferred to Düzce.
Republican Period: During this period, showing a great improvement Duzce Turkey as it is everywhere 'was the busiest and richest district. With the passing of the D-100 highway and the TEM highway, it came to the fore in the national and international dimension. After the August 17 and November 12, 1999 earthquakes, it was the 81st city on 9 December 1999 to be able to develop again in a short time.
