Italian unification posed a national question only in partial aspects, not fully

Evidence

The most strident contradiction was created by this series of facts. The urban force of the South could not be considered as something on its own, independent of that of the North. To pose the question in such a way would have meant asserting in advance an incurable “national” rift—a rift so serious that not even a federalist solution would have been able to heal it. It would have meant asserting the existence of separate nations, between which all that could have been achieved was a diplomatic-military alliance against the common enemy, Austria. (The sole element of community or solidarity, in short, would have consisted simply in having a “common” enemy.) In reality, however, there existed only certain “aspects” of such a national question, not “all” the aspects nor even the most essential ones. — Antonio Gramsci, Selections from the Prison Notebooks, 532
