Castelli set up his government in Chuquisaca, where he presided over the change of regime for the entire region. He planned the reorganization of the Mines of Potosi, and a reform at the University of Charcas. He proclaimed the end of native slavery and servitude in Upper Peru, and the natives were granted political rights equal to those of the criollos. Castelli forbade the establishment of new convents and parishes to avoid the common practice that, under the guise of spreading Christian doctrine, the natives were forced into servitude by religious orders. He authorized free trade and redistributed land expropriated from the former workers of the mills. The decree was published in Spanish, Guarani, Quechua, and Aymara; he established several bilingual schools as well. Several Indian chiefs participated in the first anniversary of the May Revolution, celebrated in Tiahuanaco, where Castelli paid tribute to the ancient Incas and encouraged the people to rise against the Spanish. Despite their welcome, however, Castelli was aware that most of the aristocracy supported the auxiliary army out of fear instead of genuine support.
