Why did Giuseppe Mazzini favor a republican Italy?

Giuseppe Mazzini favored a republican form of government for Italy because he believed it was the only system capable of ensuring that all citizens were treated as free and equal brothers under the law of God and humanity.1

As the founder of the Young Italy movement, Mazzini argued that a republic was essential to the moral and spiritual revival of the Italian people. He maintained that a unified, republican state was necessary to provide the nation with true strength, asserting that without unity, there is no real nation. Unlike the moderate liberals of his time, who were often willing to compromise with absolute monarchs, Mazzini was an uncompromising republican who sought to achieve independence through popular participation and political revolution rather than through the existing autocratic structures.123
