[5] But Francis I of France, the Archbishop of Lyon, and the Bishop of Grenoble all objected, and on 22 September 1516, Pope Leo was obliged to cancel the establishment of Chambéry as an archdiocese.

Each member of the clergy was required to swear an oath to the Constitution or be deported from French territory; an exception was made for clerics over sixty years of age.

[10] Unaware of the bishop's death, Pope Pius VI wrote a letter on 5 October 1793, commiserating with and encouraging the cathedral Chapter of Chambéry in their sufferings, and warnihg them of the dangers of schism.

[11] Under severe pressure from First Consul Napoleon Bonaparte,[12] Pope Pius VII issued the bull "Qui Christi Domini vices" on 29 November 1801.

[15] The Bull "Beati Petri," signed by Pope Pius VII on 17 July 1817, made Chambéry, which had been assigned to the Kingdom of Sardinia (1720–1861) by the Congress of Vienna, the seat of an archdiocese, with the diocese of Aosta as a suffragan.

In 1860, the French Empire and the Kingdom of Sardinia (Piedmont) agreed to allow France to annex the duchy of Savoy, including Chambéry, St.Jean de Maurienne, Annecy, Tarentaise, and Nice.

[19] This created an anomaly, from the point of view of national governments, that the Diocese of Aosta in the Kingdom of Sardinia had been a suffragan of the archbishop of Chambéry, in France, since 1819.

Napoleon III therefore petitioned Pope Pius IX to adjust the borders of dioceses and ecclesiastical provinces, making Aosta a suffragan of the archdiocese of Turin.
