HISTORICAL NOTE: the usurper, ex-prince D. Miguel de Bragança, since his banishment and outcast (1834), misused several titles belonging to the Kings of Portugal and to the Royal House of Portugal, a practice continued by his descendants (until ours days). In an abusive and illegal manner (in the light of the law applicable until October 5, 1910), they usurped, namely, the titles of King, Royal Prince, Prince of Beira, Duke of Bragança, Duke of Guimarães, Duke of Viseu, etc., systematically harassing the Reigning Royal Family in Portugal until the end of the Monarchy; They continued with the same abuse during the life of King Manuel II and the Queen Dona Amélia of Orléans. Continuing to do so, nowadays, trying to deceive the Portuguese people, shielding themselves in the actions of the dictator Salazar.
