Members of the Knights of Malta walk in procession towards St. Peter's Basilica during a celebration to mark the 900th anniversary of the Order of the Knights of Malta, at the Vatican, Saturday, Feb. 9, 2013. The order traces its history to the 11th century with the establishment of an infirmary in Jerusalem that cared for people of all faiths making pilgrimages to the Holy Land. It is the last of the great lay chivalrous military orders like the Knights Templars that combined religious fervor with fierce military might to protect and expand Christendom from Islam's advance during the Crusades. In February 1113, Pope Paschal II issued a papal bull recognizing the order as independent from bishops or secular authorities, reason for Saturday's anniversary celebrations at the Vatican.
