On 15 October 1942, in the cathedral of Petrópolis in Brazil, Duarte Nuno married Princess Maria Francisca of Orléans-Braganza (8 September 1914 – 15 January 1968), daughter of Pedro de Alcântara, Prince of Grão-Pará.
The marriage was particularly popular since Maria Francisca was the great-granddaughter of Pedro II of Brazil, the younger brother of Queen Maria II.
The marriage thus united the two rival lines of the Portuguese royal family.
Maria Francisca and her family were also viewed as representatives of a liberal monarchy as opposed to the traditional conservatism of Duarte Nuno's family.
