Early in 1809 a group of merchants and militiamen led by alzaga attempted to remove Santiago de Liniers without success in this endeavour. Saavedra and his soldiers gave a backing very strong the viceroy survived. But not missed much time so that the Government of Seville resolved to dismiss him appointing Baltasar de Cisneros as a new manager of the Rio de la Plata. Moreno, also a merchant and a strong liberal ideology, began his political career a few years before when he managed inter alia, very heavily develop economic initiatives implemented in 1777, by the then newly appointed first viceroy of the Rio de la Plata, Pedro Antonio de Cevallos of open trade in the colonies of the South with the Metropolis by eliminating the absurd and harmful trade monopoly regime. The pressure of the young Creole and desperation of Viceroy Cisneros to get new merchandise not already coming from Spain, which was in the hands of the French, They forced to declare the practice of free entry of goods. This decree meant a great friction with the factories of some municipalities and cities of the interior that could compete, yet, against smuggling, imports or exports of Buenos Aires, which handled the port and the Customs during the stage of monopoly. The areas that lost economically include Corrientes and missions that were adversely affected by the opening of the port of Buenos Aires big. Some years later, these provinces, were relegated from the Argentine general development. Varied historical sources argue that the important loss of their industrial power many correntinas families did not support the movement of Moreno and Saavedra and years later supported Yes, Jose Gervasio Artigas, the Uruguayan caudillo. After the Decree of economic and commercial freedom, Moreno was so well positioned within the Buenos Aires oligarchy, which was transformed into the soul of the revolution of may, but was not the visible head.
