The village was established in 1543 during the
Ottoman era by
Oghuz Turks (Turkmens). The name of the town probably refers to a certain Yenice Bey who was a rebellious Turkmen chief who lived in the first half of the 16th century. In the early years of the 19th century, the town was briefly occupied by the rebellious
İbrahim Pasha of Egypt. After the
First World War, Yenice was shortly
occupied by France (
cf. Sykes–Picot Agreement). After the
Treaty of Ankara, 20 October 1921, Yenice was ceded to Turkey. On 30 January 1943, during the
Second World War, the
Adana Conference between the Turkish president
İsmet İnönü and the British prime minister
Winston Churchill was held in a railway carriage at
Yenice Railway Station to discuss Turkey's role in the war. The carriage is now displayed in the station. In 1953 Yenice was declared a township. == Economy ==
