The Knights of Santiago is a Roman Catholic military order founded in the 12th century in Spain. Its primary mission was to protect pilgrims traveling to the shrine of Santiago de Compostela, where the remains of Saint James are believed to be buried. The order played a significant role in the Christian Reconquista, fighting against Muslim forces in the Iberian Peninsula. Members of the order, known as Santiago Knights, took vows of chastity, poverty, and obedience. They were recognized for their distinctive white mantles adorned with a red cross. Over time, the order evolved into a religious and charitable organization, contributing to various social and cultural initiatives.
