How does Mazzini express the main ideas of liberal nationalism?

Nationalism or nationalism, ideology, including national, ethnic, and national identity, the nationalist (English: Nationalist) advocated in the (national and ethnic) ideology mutual recognition of the premise to have The national community of the same nationality is the "basic unit" of human group life, and serves as the basis for shaping specific cultural and political ideas. Specifically, the proposition is that the nation is "the only legal basis for the existence of the state" and that "all ethnic groups have the right to self-determination and nation-building." Nationalism and patriotism are often (and not always, sometimes not necessarily) indistinguishable. In the past, nationalism had largely emphasized the national community, and more recently it had focused on cultural or political communities represented by the state or government.
