Count of Miranda do Corvo
Count of Miranda do Corvo (in Portuguese Conde de Miranda do Corvo) was a Portuguese title of nobility created by a royal decree, dated from March 21, 1611, by King Philip II of Portugal, also known as Philip III of Spain, and granted to Dom Henrique de Sousa Tavares. Henrique was 26th Lord of the House of Sousa, Lord of Miranda do Corvo and Alcaide (Mayor) of Arronches. The Prince Regent Pedro, Duke of Beja, on behalf of King Afonso VI of Portugal, granted the new title of Marquis of Arronches (in Portuguese Marquês de Arronches) by a royal decree dated from June 27, 1674 to Henrique de Sousa Tavares, who was already 3rd Count of Miranda do Corvo. On May 13, 1796, a royal decree issued by Queen Maria I of Portugal, upgraded the title of Count of Miranda do Corvo to Duke of Miranda do Corvo (in Portuguese Duque de Miranda do Corvo), who should be beard by the Duke of Lafões heir during his father's life.
