When Spain, in 1566, undertook the conquest of the Philippines, they were not erected into a separate government but were placed under the vice-royalty of New Spain or Mexico, with a governor or captain-general in command. When, in 1581, the bishopric of Manila was founded, it was suffragan to the archbishopric of Mexico and was not erected into a metropolitan see until 1595. The islands therefore were included in the district of the Mexican Inquisition, but they were too sparsely occupied by Europeans for the tribunal to think it necessary to establish an organization there. When, however, the first bishop, the Dominican Domingo de Salazar, reached his see in 1572, his zeal led him at once to establish an episcopal Inquisition with a fiscal and other officials, and the regular inquisitorial procedure; he soon found culprits and held a formal auto de fe, exercising his assumed authority with excessive severity. Don Francisco de Zuñiga, a youth of 20, in a discussion, had thoughtlessly declared fornication to be no sin; then on reflection he denounced himself, but notwithstanding this he was obliged to appear in an auto with a gag, and was banished for ten years, with a threat of two hundred lashes if he returned. Canon Francisco de Pareja, suspected of being one of the Alumbrados of Llerena, when arrested for solicitation, hanged himself in prison. Some of Salazar's penitents on reaching Mexico complained to the tribunal and thus aroused its attention to this invasion of its jurisdiction, when it lost no time in vindicating its rights.
