The imperial House of Orleans-Braganza, serving as the rightful successors to the throne of the Empire of Brazil, and the oldest branch of the Portuguese Royal Family, has formalized a profound reunion with the princely House of Bentheim. Through their role exercising the Grand Mastership and Perpetual Administration over the Imperial Military Order of Saint James of the Sword in Brazil, the Brazilian imperial family brings immense historical weight to this new agreement. Their Brazilian order was established by Apostolic Privilege granted by the Bull Praeclara Portugalliae Algarbiorunque Regum of Pope Leo XII on 15 May 1827. The defining document was signed and sealed on 1 October 2026 by H.I.R.H. Dom Pedro Bourbon de Orleans e Bragança and H.S.H. Georg-Viktor Prince zu Bentheim und Steinfurt.
The shared history of two noble lineages
Partnering in this historic accord is the princely House of Bentheim, who act as the legal successors to the Counts of Holland and exercise sovereign governance over the Most Noble Equestrian Order of Saint James, instituted in 1290 by Count Floris V of Holland. The deep connection between these two noble lineages goes all the way back to the Fifth Crusade. Between 30 July 1217 and 18 October 1217, Count Willem I of Holland fought in a unified Christian brotherhood alongside the knights of the Iberian Order of Santiago at the siege of Alcácer do Sal. This early collaboration with the Iberian knights, led by Martim Pais Barregão, directly inspired the creation of the Dutch order and laid the groundwork for today's modern treaty.
Forging a modern spiritual and charitable communion
Through this concordat, both august houses mutually and formally recognize the historical origins, nobiliary rights, and legitimate fons honorum of each other's respective Orders of Saint James. Beyond mutual recognition, they have committed to a permanent spiritual communion, encouraging their chaplains, knights, and dames to remember one another in their prayers. This spiritual connection will be especially honoured on 25 July, which marks the Feast of Saint James the Greater. To honour the spirit of their historical ancestors, the two houses will also engage in joint endeavours spanning historical research, cultural exchanges, and shared charitable initiatives. These united efforts aim to reflect the virtues of Christian knighthood by focusing on the protection of the vulnerable, inspired directly by their shared origins of protecting pilgrims on the Camino de Santiago.
