History.
The department is one of the 83 French departments made during the French revolution, on 4 March 1790. The department was created mainly from parts of the former provinces of "Orléanais" (Beauce) and "Maine" (Perche), but also parts of the old "Île-de-France".
The new department had six districts: Chartres, Châteaudun, Châteauneuf-en-Thymerais, Dreux, Janville and Nogent-le-Rotrou. The capital (now prefecture) was Chartres.
In 1800, with the creation of the "arrondissements" in France, the six districts were changed into four "arrondissements": Chartres, Châteaudun, Dreux and Nogent-le-Rotrou.
On 10 September 1926, the "arrondissement" of Nogent-le-Rotrou was eliminated but in 1943 Nogent-le-Rotrou became again an "arrondissement" of the department.
