Censorship in Mexico
The Mexican Inquisition, usually working under the direction of the Spanish Inquisition, fortified the effort to censor books within Spain’s overseas dominions by printing official proclamations that served as updates to the Spanish Index librorum prohibitorum
and the Index librorum expurgatorum
. Most often published as single-sheet broadsides bearing the official seals and signatures of the ecclesiastical authorities, these decrees warned that violators of censorship laws were subject to excommunication.
