Marquis of Valença
Marquis of Valença (in Portuguese Marquês de Valença) was a Portuguese title of nobility granted by royal decree of King Afonso V of Portugal, dated from October 11, 1451, to Dom Afonso of Braganza (1400–1460), who already was 4th Count of Ourém. It is the 1st Marquis title in Portugal. This title was only renovated later in the 17th century: when the 7th Count of Vimioso (belonging to the 1st Marquis’ lineage) died, King Pedro II of Portugal, through a special decree, issued on December 13, 1681, legitimated the count's natural and only son, Francisco de Paula de Portugal e Castro (Francis III), as 8th Count, and also granted him the title of 2nd Marquis of Valença.
