Knights Hospitaller
The Order of Knights of the Hospital of Saint John of Jerusalem (; ), also known as the Order of Saint John, Order of Hospitallers, Knights Hospitaller, Knights Hospitalier or Hospitallers, was a medieval and early modern Catholic military order. It was headquartered in the Kingdom of Jerusalem, on the island of Rhodes, in Malta and St Petersburg.
Knights Templar (Freemasonry)
Like the Masonic Red Cross of Constantine being inspired by the Sacred Military Constantinian Order of Saint George and the Order of Malta being inspired by the Sovereign Military Order of Malta, the Masonic order of Knights Templar derives its name from the medieval Catholic military order Knights Templar. However, it does not claim any direct lineal descent from the original Templar order.
