The history of the County of Nevers is closely connected to the
Duchy of Burgundy. The counts also held the
County of Auxerre in the 11th and 12th centuries, and the county was held by the
count of Flanders and then the duke of Burgundy again in the 14th century. In 1539, it became a duchy in the
peerage of France. For a time, it was held by a
cadet branch of the
House of Gonzaga. This branch inherited the
Duchy of Mantua from the senior Gonzaga line (when it became extinct in 1627) and ruled Mantua until 1708, when the branch died out in the male line.
Charles IV Gonzaga sold the duchies of Nevers and
Rethel in 1659 to
Cardinal Mazarin. His family held the duchy of Nevers until the
French Revolution. ==Counts of Nevers==
