Treaty of Pilar

It was signed in the city of Pilar, Buenos Aires on 23 February 1820 by governor Estanislao López for Santa Fe, caudillo 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.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 Paraná and Uruguay by the signatories.It also called for deputies sent by them to be gathered in a congress in San Lorenzo, Santa Fe, 60 days afterwards, to decide on a federalist form of government.It noticeably excluded José Gervasio Artigas, former leader of the federalist 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.
