How did Stendhal's friendship with Italian liberals affect his life?

Stendhal’s friendship with Italian liberals and Carbonari patriots during his residence in Milan significantly impacted his life by leading to his political compromise in the eyes of the Austrian occupying authorities. This association ultimately forced him to leave Milan in 1821.1

Beyond these political consequences, his time in Italy was a formative period that solidified his literary vocation. During this stay, he immersed himself in the study of music and the visual arts, and he published his first books, including Lives of Haydn, Mozart and Metastasio and History of Painting in Italy. His experiences in Italy, characterized by both intellectual discovery and deep emotional disappointment, remained a central, determining influence on his life and literary works.1
