Ordo Supremus Militaris Templi Hierosolymitani

The Ordo Supremus Militaris Templi Hierosolymitani (OSMTH), also known as Knights Templar International, is a self-styled order founded in 1945 by Antonio Campello Pinto de Sousa Fontes (1878-1960), claiming to be a continuation of the self-styled l'Ordre du Temple founded in 1804 by Bernard-Raymond Fabré-Palaprat.

Fernando Campello Pinto Pereira de Sousa Fontes succeeded his father as the head of the order in 1960.

There are a number of Orders who claim they are OSMTH and the order exists in each country under different jurisdictions. In America, the order is known as the Sovereign Military Order of the Temple of Jerusalem, Inc. Another American group, calling itself the Loyalists or OSMTH-Regency and who recognised the leadership of Pereira de Sousa Fontes is entitled the Ordo Pauperum Commilitum Christi et Templi Solomonis, Equis Templi.

The OSMTH-KTI organisation that is registered in Geneva, Swiss Reg No: CH-660.1.972777-4 and is in Special Consultative Status with the Economic and Social Council of the United Nations has over 5000 active members in Austria, Bulgaria, Canada, England & Wales, Finland, France, Germany, Greece, Italy, Mexico, Norway, Portugal, Scotland, Serbia and in the United States.

OSMTH-KTI does not officially recognize the claims laid out in the Larmenius Charter as historically valid.

OSMTH-KTI, which is open to Christians of any denomination, operates as a charity, and engages in diplomatic and humanitarian works. They should not be confused with a multitude of other self-styled "Knights Templar", or the Masonic Knights Templar.

Christian men who join the organisation call themselves "Knights" with the republican honorific of Chevalier and females are termed "Dames" with the republican honorific of Chevaleresse (or Chevalière).
