Input: Passage: The central figure in the overthrow of Rosas, Entre Rios Governor Justo Jose de Urquiza, was granted the power of a head of state by the Palermo Protocols of April 6, 1852. This provoked resistance in Buenos Aires, however, which then refused to ratify the San Nicolas Agreement of May 31. The prospect of having the Argentine Congress headquartered in Santa Fe proved especially objectionable, and Urquiza's June 12 appointment of former President Vicente Lopez y Planes failed to turn public opinion in Buenos Aires. Colonel Bartolome Mitre rallied the Assembly against the San Nicolas Accords. The most contentious issue remained the Buenos Aires Customs, which remained under the control of the city government and was the chief source of public revenue. Nations with which the Confederation maintained foreign relations, moreover, kept all embassies in Buenos Aires (rather than in the capital, Parana).
