Buenos Aires was declared a rogue city by the Council of Regency, which appointed Montevideo as capital of the viceroyalty of the Río de la Plata, and Francisco Javier de Elío the new viceroy. However, the May Revolution was not initially separatist. Patriots supported the legitimacy of the Juntas in the Americas, whether royalists supported instead the Council of Regency; both ones acted on behalf of Ferdinand VII. All of them believed that, according to the retroversion of the sovereignty to the people, in the absence of the rightful king sovereignty returned to the people, which would be capable to appoint their own leaders. They did not agree on who was that people, and which territorial extension had the sovereignty. Royalists thought that it applied to the people on European Spain, who had the right to rule over all the Spanish empire. The leaders of the May Revolution thought that it applied to all the capitals of Spanish kingdoms. José Gervasio Artigas would lead later a third perspective: the retroversion applied to all regions, which should remain united under a confederative system. The three groups battled each others, but the disputes about the national organization of Argentina (either centralist or confederal) continued in Argentine Civil War, for many years after the end of the war of independence.
