 Liniers was succeeded by Baltasar Hidalgo de Cisneros a few months later , who pardoned the mutineers to reduce political conflicts . Cisneros allowed free trade as well , as instructed by the Junta of Seville , which benefited British merchants ; Britain was allied with Spain in the Peninsular War . The agents of the Consulate of Cadiz asserted that this would hurt the local economy , moral values , social usages , religious practices , and the loyalty to Spain and its monarchy . As a result , Cisneros closed trade again , restoring the Spanish monopsony . A group of hacendados ( owners of haciendas ) , who did not feel adequately represented at the Cabildo , asked Moreno to defend them . Moreno wrote The Representation of the Landowners , a report that represented the export interest of the landowners , encouraged free trade , and condemned the privileges of the merchants benefited from the monopsony . It is considered the most comprehensive economic report from the time of the viceroyalty . It represented the new European economic ideas , and noted that the legal monopsony with Spain did not prevent British goods from being smuggled . Several authors have questioned Moreno 's authorship of the paper , considering it instead an update of another , previously drafted by Manuel Belgrano , Secretary of the Commerce Consulate of Buenos Aires , written to make a similar request to the former viceroy Liniers . This report , as well as Moreno 's prestige in the colonial society , helped him gain the confidence of Cisneros . Yet secretly , Moreno supported the plan to dismiss the Viceroy .
