 Mariano Moreno had several contacts with groups seeking the removal of Cisneros , but was not strongly involved with the May Revolution , which considered the fall of the Junta of Seville a reason to depose the viceroy and create a local junta . At the time , Moreno was still loyal to Álzaga . He attended the May 22 open Cabildo , but according to the father of Vicente Fidel López and the father @-@ in @-@ law of Bartolomé Mitre ( both direct witness ) he stayed silent at one side and did not join the debate . He voted for Saavedra 's proposal : to remove viceroy Cisneros and replace him with a Junta . Manuel Hermenegildo Aguirre , captain of hussars , proposed that the Cabildo take the reins of government , with five men appointed as counselors , Moreno among them . However , nobody else voted for that proposal , and it was the only one that included him . Moreno felt betrayed when the Cabildo twisted the results of the open Cabildo and created a Junta that would be headed by Cisneros . He refused any further contacts with the revolutionaries and stayed home during the remaining events . The definitive members of the Junta came from a popular petition signed on May 25 , which was given to the Cabildo . The reasons of Moreno 's inclusion in the list are unclear , as with all other members of the Junta . A commonly accepted theory considers it to be a balance between Carlotists and Alzaguists .
