Knights Hospitaller
The Knights Hospitaller or more correctly The Order of Knights of the Hospital of Saint John of Jerusalem (Latin: Ordo Fratrum Hospitalis Sancti Ioannis Hierosolymitani), were a medieval and early modern Roman Catholic military order of which two major Orders of Chivalry evolved, the Order of the Knights of St. Lazarus and the Order of the Knights of St. John, later to be known as the Sovereign Military Order of Malta. It was headquartered in the Kingdom of Jerusalem until 1291, on the island of Rhodes from 1310 until 1522, in Malta from 1530 until 1798 and at Saint Petersburg from 1799 until 1801. More recently, there are several successor, humanitarian organizations.
History
The Hospitallers arose around the work of an Amalfitan hospital located at the Muristan site in Jerusalem, founded around 1023 by Blessed Gerard to provide care for poor, sick or injured pilgrims to the Holy Land. After the Western Christian conquest of Jerusalem in 1099 during the First Crusade, the organisation became a religious and military order under its own charter, and was charged with the care and defence of the Holy Land. Following the conquest of the Holy Land by Islamic forces, the Order operated from Rhodes, over which it was sovereign, and later from Malta where it administered a vassal state under the Spanish viceroy of Sicily.
The Order was weakened by Napoleon's capture of Malta in 1798 and became dispersed throughout Europe. It regained strength during the early 19th century as it repurposed itself towards humanitarian and religious causes. The modern continuation of the mediaeval Order is the Roman Catholic Sovereign Military Order of Malta, headquartered in Rome; allied Protestant orders are headquartered in the United Kingdom, Germany (Johanniter-Orden), the Netherlands and Sweden.
