Xavier de Maistre of Savoy (at the time, a region of the Kingdom of Sardinia), lived largely as a military man, but is known as a French writer. The younger brother of noted philosopher and counter-revolutionary Joseph de Maistre, Xavier was born to an aristocratic family at Chambéry in October 1763. He served when young in the Kingdom of Sardinia army, and wrote his fantasy, Voyage autour de ma chambre (Journey Around My Room, published 1794) when he was under arrest in Turin as the consequence of a duel.
Xavier shared the politics and the loyalty of his brother, and after a French revolutionary army annexed Savoy to France in 1792, he left the service, and eventually took a commission in the Russian army. He served under Alexander Suvorov in his victorious Austro-Russian campaign and accompanied the marshal to Russia in 1796. By then, Suvorov's patron Catherine II of Russia had died, and the new monarch Paul I dismissed the victorious general (partly on account of the massacre of 20,000 Poles after he conquered Warsaw). Xavier de Maistre shared the disgrace of his general, and supported himself for some time in St. Petersburg by miniature painting, particularly landscapes.
In 1803, Joseph de Maistre was appointed the Sardinia's ambassador to the court of Alexander I, Tsar of Russia. On his brother's arrival in St. Petersburg, Xavier de Maistre was introduced to the Minister of the Navy, and was appointed to several posts including director of the Library, and of the Museum of Admiralty. He also joined active service, and was wounded in the Caucasus, attaining the rank of major-general. In 1812 he married the Russian lady, related to the Tsars, Mrs. Zagriatsky, and established himself in his adopted country, even after the overthrow of Napoleon, and the consequent restoration of the Piedmontese dynasty.
