The monograph is dedicated to the history of the oldest spiritual and chivalric order of the Roman Catholic Church. Throughout its centuries-old history, the order was repeatedly forced to change its location, and the name of the order and its knights changed. In the beginning they were called Hospitallers, or Johannites, from 1291 "Knights of Cyprus," from 1306 "Knights of Rhodes." Only when in 1530 the order received the island of Malta from the Holy Roman Emperor of the German nation Charles V, it became known as the "Maltese."
