In 1790, Pope Pius VI entirely revised the ecclesiastical map of France to fit the new administrative map: dioceses were now to coincide with departments (the new administrative units), and consequently all Ancien Régime dioceses disappeared. Many former bishoprics remained heads of the new dioceses, but many cities lost their bishop. But the papacy did not accept those changes, and for more than a decade, the new French ecclesiastical hierarchy was technically in schism with Rome.
In 1801, following the Concordate First Consul Napoleon Bonaparte signed with Pope Pius VI, a compromise was found, but it was not before the late 1810s that a stable ecclesiastical organisation was reached, in which one diocese was more or less coterminous with one department. A few exceptions were retained, especially in departments where there was a particularly numerous population.
In December 2002, Pope John Paul II completely redrew the map of French ecclesiastical provinces: for this, see the post-2002 List of the Roman Catholic dioceses of France.
The following is a list of French ecclesiastical provinces and dioceses from 1825 to 2002. Except where stated, one diocese coincided with one department.
