In the years following the conquest of Central Mexico by
Hernán Cortés, New Spain had been governed by a
military government, generally with the objectives of maximizing personal economic gains by the Spanish conquistadors. Hoping to establish a more orderly government, to reduce the authority of Cortés, and secure the authority of the Spanish crown in the New World, on December 13, 1527 the metropolitan government of
Charles V in
Burgos named the
Real Audiencia de México to take over the government of the colony. This Audiencia consisted of a president and four
oidores (judges). Nuño Beltrán de Guzmán was named president. His oidores were
Juan Ortiz de Matienzo,
Diego Delgadillo, Diego Maldonado and Alonso de Parada; these two last fell sick during the voyage to New Spain and died shortly after arrival. At the time Guzmán was serving as governor of Pánuco, so Charles ordered the judges to assemble in
Veracruz and from there make a joint entrance into the capital. The four from Spain, however, did not wait for the arrival of Guzmán, and proceeded directly to the capital. They arrived on December 8, 1528, taking over the government on the following day. They were given a splendid reception by the city government. Guzmán arrived a few days after the others. The first
bishop of Mexico,
Juan de Zumárraga, had arrived in the capital only a few days before the oidores. The instructions given to the Audiencia included a recommendation for good treatment of the indigenous people and a directive that the investigation into the conduct of Cortés and his associates
Pedro de Alvarado,
Alonso de Estrada,
Rodrigo de Albornoz,
Gonzalo de Salazar and
Pedro Almíndez Chirino be concluded within 90 days. Most of these associates had participated in the government in the proceeding few years while Cortés was in Honduras, with a lot of in-fighting among themselves and injustices to the population, both Spanish and Indigenous. Cortés himself was now in Spain, where he was defending his conduct and appealing his loss of authority to Charles. Cortés had some success with his appeal, being named Marqués del Valle de Oaxaca and receiving some other honors. Nevertheless, Guzmán was now in charge in New Spain. Among his official acts was placing plaques bearing the royal coat of arms on the principal buildings of the capital, to stress that sovereignty resided in the king, not in Cortés. He had Pedro de Alvarado arrested for questioning the loyalty of Gonzalo de Salazar. There was already some animosity between Cortés and Guzmán, because the former had been reluctant to recognize the latter as governor of Pánuco. The later events made the two enemies. The Audiencia also banned direct communication with the court in Spain. This was so effective that Bishop Zumárraga felt the necessity of hiding a letter sealed in wax in a cask, to be smuggled to the Spanish authorities by a confederate sailor. In 1530, upon Hernán Cortés' return to New Spain, Guzmán was removed from the office of President of the Audiencia and instead appointed governor of
Nueva Galicia. As governor of Nueva Galicia he continued his politics of violent submission of the Indians of the
Gran Chichimeca and came into conflict with church authorities such as
Juan de Zumárraga, the Bishop appointed as Protector of the Indians, and Bishop of Michoacán
Vasco de Quiroga. He also founded several cities that still exist such as
Zacatecas,
Querétaro and
Guadalajara. In 1531 Zumárraga published a treatise decrying Guzmán's 1529 campaign as unjust. Guzmán, who had by then made many enemies, fell out of favor with the authorities and the Second Audiencia. In 1533 he was removed from the Governorship of Pánuco and in 1534 of that of Nueva Galicia. In 1537 he was charged with treason, jailed and later expelled from New Spain. ==As conqueror of western Mexico==
