Starting from the assumption that there is an indissoluble link between the sovereignty and a notion of citizenship whatsoever, the author analyses, among many possible meanings, two "ideal types" which have differently had a part in the process of modern State building: citizenship in a «vertical» meaning, that is a relationship between the individual and the sovereign, and citizenship in a «horizontal» meaning, that is a collective identity, binding all individuals on the basis of a common political membership. After following the «great neutralisation» of the Nineteenth Century, when citizenship changes into the new dimension of "nationality", some considerations are developed about the relationship between sovereignty and citizenship in the Twentieth Century Constitutional State, when the idea of a "national" citizenship, sometimes as vertical relationship between the individual and the State, sometimes as consciousness of a collective membership, is still at the heart of our legislation. Finally, the author looks forward to the future, in a time when the relationships between citizenship and sovereignty are changing their appearance, assuming a new balance.
