While young, he attended first the college of nobles in Milan and later studied in Como and then moved to Venice and finally to Siena.

Having embarked on his diplomatic career, in 1802 he obtained his first official post at the Napoleonic Italian Republic as assistant secretary to the Consulta of State.

His career came to an abrupt end, however, in 1804 when he decided to volunteer in the Grande Armée in Italy in the artillery branch, receiving public praise from the president, Francesco Melzi d'Eril, for being the first nobleman to join.

As an inheritance that he received from his grandfather through his mother, Litta became the owner of the Palazzo Brentano in Corbetta which he lived occasionally, especially during the summer.

The work, which began in 1814 after the military campaigns alongside France, enhanced the numerous noble families of the Italian peninsula, particularly those from Milan, of which Litta Biumi himself was a representative.
