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.
Sovereign Military Order of the Temple of Jerusalem
The order exists in each country under different jurisdictions. In America, the OSMTH is known as the "Sovereign Military Order of the Temple of Jerusalem, Inc." (SMOTJ) - this being the English rendering of the Latin name. They should not be confused with a multitude of other self-styled "Knights Templar", or the Masonic Knights Templar.
