Works & Achievements
As a member of the Conservative Senate, he took part in the vote that made Bonaparte First Consul for Life — a decisive step toward the restoration of strong personal rule in France.
He participated in the historic vote that transformed the Consular Republic into a hereditary Empire and conferred upon Napoleon Bonaparte the title of Emperor of the French, completing the restoration of a monarchical system.
His regular attendance in the Senate over eight years was in itself a major political contribution: as a former nobleman who had rallied to the new regime, he lent the Napoleonic government the symbolic endorsement of a lineage whose prestige stretched back several centuries.
Anecdotes
Antoine-César de Choiseul-Praslin belonged to one of the most illustrious dynasties of the Ancien Régime: his cousin César-Gabriel de Choiseul had served as Foreign Minister under Louis XV, making the name Choiseul-Praslin synonymous with distinguished service to the monarchical state. This prestigious lineage earned him immediate recognition from Napoleon, who was actively seeking to win over such families in order to legitimize his regime.
Born in 1756, he was thirty-three years old when the Bastille fell. Like many aristocrats of his generation, he had to navigate the years of the Terror — a period when bearing a noble name was enough to attract suspicion. His ability to survive those turbulent years and emerge as an imperial senator speaks to the complexity of individual paths through the Revolution.
His appointment to the Conservative Senate perfectly illustrates the policy known as the 'ralliement' pursued by Bonaparte: by bringing former nobles into the heart of imperial institutions, the First Consul — and later Emperor — sought to reconcile the France of the Ancien Régime with the new France. Choiseul-Praslin thus stood among those 'living bridges' between two worlds that Napoleon knew how to use to great effect.
As a Grand Officer of the Legion of Honor, he was among the first recipients of this order, created in 1802. At the great imperial ceremonies — at Les Invalides or the Tuileries — he wore the broad red sash with its five-pointed enameled cross, symbol of a new France that now honored merit and service as much as birth.

Daily Life
Morning
The senator began his day by reading the *Moniteur universel*, the sole official newspaper publishing decrees, military bulletins, and government news. He would then receive his private secretary to dictate administrative correspondence before heading to Senate sessions on meeting days.
Afternoon
On session afternoons, his berline carriage took him to the Palais du Luxembourg, where he joined fellow senators to deliberate on the *sénatus-consultes* submitted by the imperial government. Outside sessions, he held audiences for petitioners seeking support or recommendations from the administration.
Evening
Evenings were devoted to dinners in the salons of the Faubourg Saint-Germain, where old and new nobility mingled in an atmosphere of political conversation, chamber music, and parlor games. These social gatherings formed an informal network of influence essential to the smooth functioning of the imperial regime.
Food
The table of a grand officer of the Empire reflected the luxury recovered after the privations of the Revolution: soups, roasted meats, game in season, and fine wines from Burgundy or Bordeaux. Dinner, the main meal served in the late afternoon, could last several hours during official receptions.
Clothing
In ceremonial dress at the Senate, he wore the regulation gold-embroidered green coat with the grand red sash of the Legion of Honor across his chest. In daily life, men's fashion under the Empire called for a lapelled frock coat, knee breeches or full-length trousers, a carefully knotted white cravat, and buckled shoes.
Housing
He resided in a private mansion in the Faubourg Saint-Germain, its décor blending the mahogany and gilded-bronze furniture characteristic of the Empire style with tapestries and paintings inherited from the *Ancien Régime*. The family estate in Champagne served as a summer residence.
