The House of Braganza (Portuguese: Casa de Bragança; ), officially the Most Serene House of Braganza (Portuguese: Sereníssima Casa de Bragança), is an important imperial, royal, and noble house of Portuguese origin, a branch of the House of Aviz, and thus a descendant house of the Portuguese House of Burgundy. The House evolved from being powerful dukes of Portuguese nobility, to ruling as the monarchs of Portugal and the Algarves, from 1640 to 1910, and as monarchs of Brazil, from 1815 to 1889.
