Coat of Arms of the Marquesses and Dukes of Loulé.
Count of Vale de Reis (in Portuguese Conde de Vale de Reis) is a Portuguese title of nobility granted by royal decree of King Philip III of Portugal (also known as Philip IV of Spain), dated from August 16th, 1628, to Nuno de Mendoça (c.1560-1632).
The Counts of Vale de Reis, who inherited several Lordships and estates, became Marquesses of Loulé (in 1799) and Dukes of Loulé (in 1862).
Originally, the family name associated with this House was de Mendoça (from the Spanish name Mendoza).
Due to different Lordships inherited by this family, several other names were added and, in the late 18th Century, they became known as de Mendoça Rolim de Moura Barreto.
