The House of Braganza (Portuguese: Casa de Bragança; Portuguese pronunciation: [bɾɐˈɣɐ̃sɐ]), officially the Most Serene House of Braganza (Portuguese: Sereníssima Casa de Bragança), is an important imperial, royal, and noble house (dynasty) of Portuguese origin. It is a branch of the House of Aviz. The House changed from being powerful dukes of Portuguese nobility, to ruling as the monarchs of Portugal and the Algarves, from 1640 to 1910. They were also monarchs of Brazil, from 1815 to 1889. The heir to the Portuguese throne was usually given the title of "Duke of Braganza".
