The objective of this article is to undertake an analysis of the concept of citizenship based on certain elements of Hannah Arendt's political theory: freedom, action, plurality and public space. Those elements are necessary to compose a concept under its specific political form, which can be enunciated as follows: citizenship is the political action of individuals who seek in the sphere of the public space of plurality the achievement of freedom. In its extension, this concept may be interpreted as a critique in front of the deficiencies of the liberal thesis of citizenship, amending its limitations. Simultaneously, it casts perspectives of proximity (and also, of remoteness) in relation to the political theory of republicanism.2130267296
