Knights of Malta and their Boats
The birth of the Knights Hospitaller dates back to around 1048. Merchants from the ancient Marine Republic of Amalfi obtained from the Caliph of Egypt the authorisation to build a church, convent, and hospital in Jerusalem, to care for pilgrims of any religious faith or race. In 1113, Pope Paschal II approved the foundation of the Hospital and placed it under the aegis of the Holy See, granting it the right to freely elect its superiors without interference from other secular or religious authorities.
As time went on, the order adopted the white, eight-pointed Cross that is still its symbol today. The eight points represent the eight beatitudes that Jesus pronounced in his Sermon on the Mount. Others also think that it refers to the eight medieval nations whose nobles made up the famous Order of St. John.
The order was forced out of Jerusalem in 1291, after the Siege of Acre. In 1310, led by Grand Master Fra' Foulques de Villaret, the knights regrouped on the island of Rhodes. From there, the defense of the Christian world required the organization of a naval force; so the Order built a powerful fleet and sailed the eastern Mediterranean, fighting battles for the sake of Christendom, including Crusades in Syria and Egypt.
From its beginning, independence from other nations granted by pontifical charter and the universally recognised right to maintain and deploy armed forces constituted grounds for the international sovereignty of the Order, which minted its own coins and maintained diplomatic relations with other states.
In the early 14th century, the institutions of the Order and the knights who came to Rhodes from every corner of Europe were grouped according to the languages they spoke. The Order was governed by its Grand Master, the Prince of Rhodes, and its Council.
In 1523, after six months of siege and fierce combat against the fleet and army of Sultan Suleiman the Magnificent, the Knights were forced to surrender, and left Rhodes with military honours.
Malta
The Order remained without a territory of its own until 1530, when Grand Master Fra' Philippe de Villiers de l'Isle Adam took possession of the island of Malta, granted to the order by Emperor Charles V, Holy Roman Emperor and his mother Queen Joanna of Castile as monarchs of Sicily, with the approval of Pope Clement VII, for which the order had to honour the conditions of the Tribute of the Maltese Falcon.
