O Herdeiro presumptivo do Imperio terá o Titulo de "Principe Imperial" e o seu Primogenito o de "Principe do Grão Pará" todos os mais terão o de "Principes". O tratamento do Herdeiro presumptivo será o de "Alteza Imperial" e o mesmo será o do Principe do Grão Pará: os outros Principes terão o Tratamento de Alteza.
(The heir presumptive of the Empire will have the title of "Prince Imperial" and his first born son the title of "Prince of Grão-Pará", all the others shall have that of "Prince". The style of the heir presumptive and the Prince of Grão-Pará will be "Imperial Highness": the other princes will have the style of "Highness".)
The only known documented and official exception was Princess Maria da Glória, who was created Princess of Grão-Pará in her own right by her father, Pedro I of Brazil, after the birth of his heir apparent, Prince Imperial Pedro (later Pedro II). She used the title in her capacity as second in the line of succession to the Brazilian throne from December 1825 to April 1826, until her father abdicated the throne of Portugal in her favor, and she became Queen Maria II.
However, after the fall of the monarchy, the family maintained the use of their titles of right.[2] In 1909 Prince Pedro Henrique of Orléans-Braganza was born, son of Prince Luís, styled Prince Imperial of Brazil, and therefore was titled Prince of Grão-Pará until the death of his father in 1920, becoming Prince Imperial.
