The origin of the Knights of Saint John was a hospital for pilgrims and the sick in Jerusalem. Raymond du Puy de Provence (1083-1160), the order's first Grand Master (1120-1160) enacted sometime about 1155 the order's first constitution. The order first quickly spread in Mediterranean Europe. Beginning in 1137, the Knights also took on the task of armed border protection, thereby becoming an ecclesiastical knightly order. In 1309, the order founded on the island of Rhodes a sovereign knightly state. After the Reformation there was, besides the original Catholic branch a new Protestant branch, the Bailiwick of Brandenburg of the Chivalric Order of Saint John of the Hospital at Jerusalem, which persists to this day. Since 1859, the Catholic branch has borne the name Order of Malta.
