Originally erected in 1822, after the Concordat as a suffragan (ecclesiastical subordinate) of the archdiocese of Chambéry, the diocese of Annecy is composed of the entirety of the department of Haute-Savoie in the Region of Rhône-Alpes.

Bishop Juste Guérin of Geneva (1639–1645) attempted to improve the quality of his clergy by instituting a seminar at Annecy for candidates for ordination lasting ten days.

He also established quarterly retreats at the seminary, and made attendance a requirement for any priest to receive a license to hear confessions.

[7] A successor to Bishop Biord, Canon Jpseph-Marie Paget, Provost of the cathedral Chapter, was nominated by Victor Amadeus III of Sardinia on 3 January 1787, and approved by Pope Pius VI on 23 April.

[8] On 13 June 1787, Canon de Thiollaz was installed as Provost of Geneva; he had been nominated by the new bishop, and was approved by Pope Pius VI, who held the right of appointment.

[14] Electors, who did not have to be Catholic or even Christian, were to meet and elect a bishop, who would be required to take the usual oaths to the French Constitution.

[18] A few weeks later, thanks to a change in political attidude of Bordeaux to the National Assembly in Paris, Thiollaz was released, and he took ship for Dover and then Bruxelles; by way of the Rhine, he reached Mainz and finally Lausanne on 8 August 1793.

[27] On 18 and 19 November 1804, Chambéry was visited by Pope Pius VII, who was on his way to Paris for the coronation of Napoleon as Emperor of the French.

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.

[33] Annecy was made an episcopal see on 15 February 1822, at the request of the recently deceased King Victor Emmanuel I of Sardinia, by Pope Pius VII, in the papal bull Sollicita catholici gregis.

[37] On 30 August 1824, Pope Leo XII authorized the transfer of the parish which had been located at the cathedral to the church of Nôtre-Dame.

[38] The first bishop of Annecy, Claude-François de Thiollaz, was nominated by King Charles Felix of Sardinia on 21 April 1822.

"[42] By the Treaty of Turin between the French Emperor, Napoleon III, and the King of Sardinia, Victor Emmanuel II, signed on 24 March 1860, Savoy and Nice were annexed by France.

[43] On 31 December 1860, Pope Pius IX sent an apostolic brief to the archbishop of Chambéry and the bishops of Annecy and of Nice, announcing that, inasmuch as they were now part of the French Empire, the terms of the apostolic letter of Pope Pius VII of 15 July 1801, and the bull "Ecclesia Christi" of 18 September 1801, now were held to apply to their dioceses as well.

It was determined that the Major Seminary building was being under-utilized, and it was therefore sold, and the proceeds used to construct a new "Centre diocesan de formation," to which the candidates for the priesthood were relocated.

In 1572, Prior Claude de Granier, who was later bishop of Geneva (1578–1602), attempted a reform of the monastery in accordance with the decrees of the Council of Trent, but was met with the opposition of 15 of his 20 monks.
