Jesuits arrived in Mexico in 1572. They had come from a Spain unified by an imperial ideology—its prime components a single faith, shared cultural values and traditions, and belief in a royal mystique—allowing, indeed encouraging, expansion of the monarchy overseas. Spanish Jesuits, some of whom articulated adherence to this ideology, by 1580 had established their religious order among the most respected corporations in Mexican society. Through preaching, ministering to the needy, and missionary work, but above all through gaining a near monopoly on secondary education in New Spain, members of the Society of Jesus achieved a position of prestige and influence within all strata of society. In order to understand, therefore, how Jesuits contributed to the maintenance of Mexican ties to Spanish empire, it is first necessary to get some idea of the nature of their system of education, its curriculum, teaching methods, and aims in New Spain.
