Knights Hospitaller

A Catholic religious and military order founded in Jerusalem to care for sick pilgrims. It later defended Crusader states and ruled Rhodes and Malta.

Hospital of Saint John of Jerusalem: A medieval hospital in Jerusalem that cared for sick and poor pilgrims and gave the Hospitallers their name. The order emerged from this hospital and its community of caregivers.
Rule of the Hospitallers: The religious regulations governing the Hospitallers’ communal life, duties, and organization. The rule gave members a shared framework for service and discipline.
Siege of Rhodes (1480): An Ottoman siege of Rhodes repelled by the Hospitallers under Grand Master Pierre d’Aubusson. The defense showed the order’s capacity to resist a major Ottoman assault.
