The 1869 Citizenship Law seemed to have put to rest the internal dispute over who was, and how one became, an Argentine; it also resolved questions about whether this quality could be revoked. Although the disagreement between Buenos Aires and the Confederation was settled, it was not long before a new wave of immigration—the very migration that the 1876 law had sought to encourage—renewed the importance of the nationality law. This law was considered, by this time, an instrument to regulate and control migration as well as a settlement policy that implied new tensions with the “friendly” powers.
