Abstract
In this text, I propose to adapt the Collective Agentivity theory of List and Pettit so as to consider nations as agents. This exercise could thus give an additional argument to collective rights theories of interest to national groups, since they can truly be recognised as subjects of rights, capable of self-determination and moral claims. Seymour collective rights theory will be used as a model in this regard. Although the political liberalism of Seymour refuses to comment on metaphysical problems, it is interesting to open up the conceptual possibility of national groups being agents in their own right. To do so, it will be necessary to determine how a national officer can take decisions and how he or she can be subjected to actions, in addition to exploring what this could imply for the collective responsibility of nations.
