Knights Hospitaller Infirmary Model

Timeline

1. c. 1099–1113Jerusalem · Holy LandAfter the crusaders captured Jerusalem, the Hospitaller brethren provided food, lodging, and medical care to pilgrims and the sick at the Hospital of St. John, gradually forming a permanent infirmary with rules and dedicated staff, laying the foundation for the order's dual military–medical functions.
2. 1101–1200Acre · Holy LandIn the 12th century the Knights Hospitaller expanded medical facilities at Acre, Margat Castle, and elsewhere, with wards segregated by gender and condition, equipped with pharmacies and surgical rooms, and staffed by trained medical brethren for daily care and treatment of war wounds.
3. 1217–1221Acre · Holy LandDuring the Fifth Crusade of 1217–1221, the Knights Hospitaller's infirmaries at Acre and elsewhere admitted large numbers of wounded soldiers and plague patients, with their model of specialized wards, stocked medicines, and religious charity in a highly active phase.
4. 1291–1300Rhodes · Eastern MediterraneanAfter the loss of Holy Land strongholds in 1291, the Knights Hospitaller brought their infirmary management experience to Cyprus, Rhodes, and European ports, with their ward rules and medicine supply systems influencing later monastic and municipal hospital organization.
