Duque de Bragança

The title Duke of Braganza in the House of Braganza is one of the most important titles in the peerage of Portugal. Since the House of Braganza acceded to the throne of Portugal in 1640, the male heir of the Portuguese Crown was known as the Duke of Braganza and Prince of Brazil until 1822, or sometimes also as Prince of Beira. The tradition of the heir to the throne being titled Duke of Braganza was revived by various pretenders after the foundation of the Portuguese Republic on 5 October 1910 to signify their claims to the throne.
