The Order of the Knights of Santiago is a Roman Catholic military order founded in the 12th century in Spain. Its primary purpose was to protect pilgrims traveling to the shrine of Santiago de Compostela, which is dedicated to Saint James the Greater. The order played a significant role in the Christian Reconquista, fighting against Muslim forces in the Iberian Peninsula. Members of the order, known as Knights of Santiago, took vows of chastity, poverty, and obedience. They wore a distinctive white cloak adorned with a red cross, symbolizing their commitment to their faith and mission. The order continues to exist today, focusing on charitable activities and preserving its historical legacy.
