Giuseppe Mazzini's work refers to his influential role in the Italian nationalist movement during the 19th century, where he advocated for the unification of Italy and the establishment of a democratic republic. His ideas emphasized the importance of national identity, civic duty, and the necessity of political change through popular will, aiming to inspire a sense of nationalism across Italy and beyond. Mazzini is often seen as a key figure in the broader wave of nationalism that swept through Europe during this period, promoting the belief that nations should govern themselves based on shared culture and heritage.
