A Spanish Jesuit missionary who introduced Christianity to the indigenous Chamorro people of Guam and established the first Catholic mission in the Mariana Islands. He's also known for his role in the martyrdom of Saint Pedro Calungsod.
Diego Luis de San Vitores is best known for founding the first Catholic church on the island of Guam, establishing a Christian presence in the Mariana Islands, and playing a pivotal role in the Spanish-Chamorro Wars. Born in Spain in 1627, San Vitores dedicated his life to spreading Christianity and educating the local population.
San Vitores was born into a noble family in Burgos, Spain, and was baptized Diego Jerónimo de San Vitores y Alonso de Maluenda. Despite his parents' wishes for him to pursue a military career, San Vitores felt drawn to religious life and entered the Jesuit novitiate in 1640. He was ordained as a priest in 1651.
In 1662, San Vitores stopped in Guam on his way to the Philippines and vowed to return to the island. He eventually persuaded King Philip IV of Spain and Queen Mariana of Austria to establish a mission in Guam, and in 1668, he set sail from Acapulco to fulfill his dream.

San Vitores landed in Guam in 1668 and was greeted by Chief Kepuha. The chief's family donated land to establish the first Catholic mission on the island, and on February 2, 1669, San Vitores established the first Catholic Church in Hagåtña, dedicating it to the "Dulce Nombre de María" (Sweet Name of Mary).
The Chamorros initially welcomed San Vitores and the other Catholic missionaries, and hundreds were readily converted. The nobles of the community may have believed that conversion would elevate their social status, while other village chiefs desired peace and stability.
San Vitores' legacy is marred by controversy due to his role in the Spanish-Chamorro Wars. While he is celebrated for bringing Christianity to Guam, his actions also led to conflict and bloodshed. Today, he remains a complex figure in Guamanian history, remembered both for his missionary work and his involvement in the wars.
