Argentine Confederation
After independence, the Republic of Paraguay and the Argentine Confederation succeeded to these disputes. On 19 July 1852, the governments of the Argentine Confederation and Paraguay signed a treaty, by which Paraguay relinquished its claim to the Misiones. However, this treaty did not become binding, because it required to be ratified by the Argentine Congress, which refused. Paraguay's claim was still alive on the eve of the war. After the war the disputed lands definitively became the Argentine national territory of Misiones, now Misiones Province.
