Tardenois

It is known among archeologists for the epipaleolithic culture known as Tardenoisian after its characteristic arrowheads, originally found at Coincy in the Tardenois in 1885.

In the Middle Ages, it became a county (comitatus) under the Carolingians, subject to visits by missi dominici (lord's envoys).

[1] Hincmar, archbishop of Reims, records around 870 that the Tardenois was under a count named Bertram, a relative of his, who exercised the bannum and held placita.

It was still regarded as a county in the late eleventh century, when it was part of the domains of Ralph IV (1038–74) and his son Simon (1074–77), counts of Valois.

During 22–26 July 1918, the Italian 2nd Corps, supported by two British divisions, launched an offensive that drove the Germans back behind Fère-en-Tardenois.
