The Fiume issue, the origin of which was, indeed, in the principle of nationality and Italianness, nevertheless emphasised, by placing it at the centre of social rights, the right of minorities and the effects this had on freedom of education. This was just one of the many contributions of the Fiuman Constitution, known to be the mother of the Constitution, especially in its socio-economic part. But it was precisely on the formation of personal identity, carried out within the framework of social formation, that the experience of the sublime constitutional minds of Alceste De Ambris and Gabriele D’Annunzio, the subject of this study, arose, demonstrating how a great nationalist was, above all, also a pluralist. The Charter of Carnaro, a great work of literary quality, will be defeated in space, but not in time, remaining, by definition and structure, also projected into the future.
