assigned the reviewing of legislation passed by Louis XVIII, and organized the National Guard in Picardy. Sébastiani was elected to the Chamber for the department of Aisne. After the Battle of Waterloo, he voted in favor of Napoleon's abdication, and, eventually, was among those assigned with negotiating a peace with the Seventh Coalition (as part of a delegation also comprising Benjamin Constant de Rebecque, the marquis de La Fayette, marquis d'Argenson and comte de Pontécoulant). During talks, he showed himself opposed to a second Bourbon return. Sébastiani spent a year in England before being allowed to return (having retired from active service and receiving half pay). Starting in 1819, after being promoted by the Duke Decazes, he was a prominent member of the Chamber of Deputies, initially representing Corsica, rallying with the Left. According to the Revue'''s comments, his political choice was unusual, reportedly astonishing both members of the Left and the moderate Decazes, a Royalist. Inside the Chamber, he joined forces with Maximilien Sebastien Foy, notably pushing projects to recognize the merits of Grande Armée veterans; a speech he held on the latter occasion, which gave praise to the French tricolor, caused an uproar among conservative deputies. During the 1824 French legislative election, his attempt to campaign in Corsica was frustrated by the local authorities representing the Royalist Government of Jean-Baptiste de Villèle, and he subsequently won 1 out of 48 votes. Instead, after General Foy's death in late 1825, he was elected as replacement in his constituency, the Aisne town of Vervins, receiving 120 votes out of 200.

During the Revolution, he parted with the Left, and made declarations in support of Charles X—including one which proclaimed that the only national flag was the white one for the Bourbons. Allegedly establishing links with the radical Aide-toi, le ciel t'aidera society in the early days of the July Monarchy, he subsequently rallied with the centrist politics of the Orléanist camp. With Laffitte, Benjamin Constant, Jean-Guillaume Hyde de Neuville, Adolphe Thiers, and others, he played a prominent part in calling Louis-Philippe to the French throne. After that, the Sébastianis became the most influential faction in Corsica, replacing the Legitimist Pozzo di Borgo family — one
