Biography
In 1668, Diego Luis de San Vitores landed in the Mariana Islands and founded the first Catholic church on Guam. A well-born Spanish Jesuit, he had petitioned the queen regent for years to fund the mission. He baptized chiefs and learned the Chamorro language. His efforts were inextricably tied to Spanish colonial power. Conflicts arose over religious practices, social structures, and the act of baptism itself, which some Chamorro viewed with deep suspicion after initial conversions were followed by illness. In 1672, a local chief whose son had died after baptism killed San Vitores and his assistant Pedro Calungsod. That killing triggered brutal Spanish military reprisals. Catholic tradition honors San Vitores as the 'Apostle of the Marianas.' To the Chamorro people, he represents catastrophic colonization and demographic collapse.
