Knights Hospitaller
- a military and religious order founded as the Knights of the Order of the Hospital of St John of Jerusalem in the 11th century僧侣骑士团(11世纪建立的教会军事团体, 初创时称为耶路撒冷圣约翰慈善事业骑士团)。
Originally protectors of pilgrims, they also undertook the care of the sick. During the Middle Ages they became a powerful and wealthy military force, with foundations in various European countries. In England, the order was revived in 1831 and was responsible for the foundation of the St John Ambulance Brigade in 1888.
