The weight of a larger population, and the economic and commercial importance of the city as the only deep water port of the country, were decisive factors in the relationship between the federated provinces. This inequality was seen since the first years of the state, when after the May Revolution the Buenos Aires "porteños" were reluctant to accept the deputies of the interior in the First Junta, and became more severe during the long period of political instability of the First and Second triumvirates and the Directory. The attempts of 1819 and 1826 to dictate a Unitarian constitution to centralize in Buenos Aires the direct administrative power over the entire national territory pushed the situation, and the political measures taken by the provinces in the successive years – such as the Federal Pact – were oriented on avoiding such situations from taking place.
