The title Duke of Braganza (Portuguese: Duque de Bragança) in the House of Braganza is one of the most important titles in the peerage of Portugal. Starting in 1640, when the House of Braganza acceded to the throne of Portugal, the male heir of the Portuguese Crown were known as Duke of Braganza, along with their style Prince of Beira or (from 1645 to 1816) Prince of Brazil. The tradition of the heir to the throne being titled Duke of Braganza was revived by various pretenders after the establishment of the Portuguese Republic on 5 October 1910 to signify their claims to the throne.
