The Order of Knights of the Hospital of Saint John of Jerusalem, commonly known as the Knights Hospitaller, is a medieval and early modern Catholic military order. It was founded in the crusader Kingdom of Jerusalem in the 12th century and had headquarters there until 1291, thereafter being based in Kolossi Castle in Cyprus (1302–1310), the island of Rhodes (1310–1522), Malta (1530–1798), and Saint Petersburg (1799–1801).
Pie postulatio voluntatis. Bull issued by Pope Paschal II in 1113 in favour of the Order of St. John of Jerusalem, which was to transform what was a community of pious men into an institution within the Church. By virtue of this document, the pope officially recognized the existence of the new organisation as an operative and militant part of the Roman Catholic Church, granting it papal protection and confirming its properties in Europe and Asia.
