Short answers, pulled from the story.
The Consulte de Lyon was an extraordinary meeting hosted in the former chapel of the Jesuit college of the Trinity in Lyon from 11 to the 26th of January 1802. Napoleon Bonaparte called this consulta as first consul during the French Consulate period.
Notable attendees included Vincenzo Brunetti, Antonio Aldini, Francesco Melzi d'Eril, Filippo Maria Visconti, Alessandro Volta, bishops of Pavia, Bergamo, Lodi and Cremona, Antonio Cagnoli, Talleyrand, Joachim Murat, and Jean-Baptiste Jules Bernadotte. The assembly also contained 452 deputies vetted by Bonaparte before they could participate.
Napoleon converted the Cisalpine Republic into the Italian Republic during his opening speech on the 26th of January. This political transformation established Napoleon as president of the newly formed state following a vote where both Aldini and Melzi had rejected the presidency.
Charles-Maurice de Talleyrand-Périgord exerted pressure on Bonaparte regarding internal leadership disputes between Italian factions. He pushed for an end to the quarrel between Aldini and Melzi and influenced how the opening speech would be delivered in Italian under pressure from him.
Nicolas-André Monsiau created a painting depicting the Consulte de Lyon between 1806 and 1808. This artwork serves as the primary visual documentation of the historical event today and subsequent historiography has relied heavily on this representation when analyzing the meeting.
