 A new viceroy, Baltasar Hidalgo de Cisneros, arrived from Europe to replace Liniers. Belgrano had failed to convince Liniers of the benefits of the Carlotist plan, so he aimed instead to convince him of refusing to give up the viceroyalty, as Liniers had been confirmed as viceroy by a Spanish king. Cisneros, appointed by the Junta of Seville, lacked such legitimacy. Liniers refused this proposal as well, and handed command to Cisneros without resistance. Belgrano later convinced the new viceroy to allow him to edit a new newspaper, the "Correo de Comercio". This allowed him to gather with other revolutionary leaders with the excuse of discussing the development of the newspaper. He also supported Cisneros when he allowed foreign trade at the port (previously only Spanish ships were allowed), but this ruling was strongly rejected by Spanish merchants. The lawyer Mariano Moreno wrote The Representation of the Hacendados, an economic essay that convinced Cisneros to maintain the free foreign trade. Some historians, such as Miguel Ángel Scenna, suggest that the essay was actually Belgrano's work, or a work by Moreno from a draft written by Belgrano. Belgrano may not have been able to present such a work himself, because he held a political office and because his past opposition to Cisneros may have risked its rejection.
