The House of Bourbon-Braganza (or Bourbon and Braganza) has its origins in a royal marriage arranged by King Charles III of Spain and his niece Queen Maria I of Portugal: in 1785 the Spanish infante Gabriel of Bourbon (1752–1788), married the Portuguese infanta Mariana Victoria of Braganza (1768–1788). It was a short marriage: they both died three years later, in Madrid, with smallpox.
Their surviving son, Peter Charles of Bourbon and Braganza (Pedro Carlos) (1786–1812), was brought up in the Portuguese court, first in Lisbon and, after 1807, in Rio de Janeiro.
As his father, he also married a Portuguese Infanta, his cousin Maria Therese of Braganza (1793–1874).
They had one child Sebastian of Bourbon and Braganza (1811–1875), Infante of Spain by birth, and Infante of Portugal by royal edict (issued in 1812). When the Portuguese Royal Family returned to Europe, Sebastian went to live in Spain (1822) but, due to his support to the Carlist pretender, he returned to Portugal (1865), where King Louis I gave him a warm reception.
This family is still today represented among the Spanish nobility (Dukes of Marchena, of Durcal, of Hernani, of Ansola).
