Treaty of Pilar
The Treaty of Pilar (in Spanish, Tratado del Pilar) was a pact signed among the rulers of the
Francisco Ramírez for Entre Ríos, and provisional governor Manuel de Sarratea for Buenos Aires, after the dissolution of the national government caused by the Battle of Cepeda. A reference to it was included in the Preamble of the Argentine Constitution of 1853
as one of the "pre-existing pacts" fulfilled by it.
The treaty established national unity, the end of hostilities between the provinces, the withdrawal of military forces from Buenos Aires, a general amnesty for politically persecuted people, and the free navigability of the rivers
Free Peoples' League, who had recently been defeated in the Battle of Tacuarembó (Eastern Bank, present-day Uruguay) by the Brazilian-Portuguese Empire. Artigas, who had been fighting along Santa Fe and Entre Ríos against the centralist government
in Buenos Aires, denounced the pact as a treason on the part of his allies. López wrote back to him explaining that the treaty was for the common good, and wondering whether Artigas was aware of the situation in the provinces.
The Treaty of Pilar was soon followed by the Treaty of Benegas, for the mutual defense of Santa Fe and Buenos Aires against the expansionist Entre Ríos and, two years later, by the Quadrilateral Treaty (including Pilar's signatories, plus Corrientes Province).
