The year 1532 was a tumultuous one in New Spain. For one thing, the crown brought the institution of slavery under regulation. The enslavement of Indians was prohibited. Also, the Audiencia brought back verdicts on the "juicios de residencia" of Cortés, the oidores of the First Audiencia, and others. Cortés and Bishop Zumárraga were acquitted; Ortiz de Matienzo and Delgadillo were convicted, but not sentenced. On April 25, 1532, Emperor Charles V signed a degree raising Antequera (now the city of Oaxaca) to the rank of a city ("ciudad").
