The coronation ceremony was held on 13 September 1779 inside the Church of Santi Ambrogio and Andrea,[1] since the Palazzo Ducale's hall of the Grand Council was not accessible due to the fire of 1777, and subsequent reconstruction work.

Brignole left office on 4 March 1781, entering the junta of the Borders and then that of the Jurisdiction; from 1788 to 1796 he was the principal state inquisitor and in this capacity he managed to approve, at the end of 1790, a new stricter regulation of censorship.

[3] In a climate now surreal and close to decline, Giacomo Maria Brignole was elected on 17 November 1796 once again as Genoese doge, a unique fact in the secular history of the Republic of Genoa.

Now pressured by troops from across the Alps, he agreed with the senators to send an embassy to Bonaparte, who negotiated the establishment of a provisional government headed by the same doge Giacomo Maria Brignole on 14 June 1797, with the aim to draft a democratic constitution.

[4] In August 1798 some important people of the former Republic of Genoa, defined "dangerous individuals", were expelled from the state, among them Brignole, Stefano Rivarola, the brothers Girolamo, Giovanni Battista Serra and the Jacobean marquis Gaspare Sauli.
