Head of the Imperial House of Brazil
The Head of the Brazilian Imperial House (Portuguese: Chefe da Casa Imperial do Brasil) is a title used by the leader of the Brazilian imperial family, currently the House of Orléans-Braganza, a descendant branch of the House of Braganza. The title of the head of the imperial house is "Emperor de jure". The current head of the imperial house is disputed between the Direct-Line descendant Dom Pedro Borbon of Orléans-Braganza and the Cadet-Line descendant Dom Prince Bertrand of Orléans-Braganza.
After the death of the last emperor of Brazil, Pedro II, in 1891, in the wake of the proclamation of the Brazilian republic on November 15, 1889, and the revocation of all titles of nobility then existing, starting with the Brazilian Constitution of 1891, it serves to indicate the heir presumptive to the extinct imperial throne of Brazil. The Brazilian monarchists affirm that, maintaining the logic established by the Brazilian Constitution of 1824, this title would respect the line of sovereignty of the jus sanguinis, being granted to the oldest male direct descendant of Emperor Pedro I of Brazil and, failing that, to the female one. If the holder of the title were a descendant of the Brazilian imperial family, as was Princess Isabel of Braganza, who married Prince Gaston of Orléans in 1864, the title would never be transmitted to her husband, this being the Head Consort of the Brazilian Imperial House.
In the same way that happened with the Brazilian emperors when they were elevated to the throne, the first-born of the Head of the Brazilian Imperial House would receive the extinct title of Prince Imperial of Brazil, and his son the title of Prince of Grão-Pará.
