Infante Diogo of Viseu (1450–1484) was the second son of Ferdinand, Duke of Viseu, and his wife Beatriz, Duchess of Viseu.
Diogo's father, uncle of King John II, was believed to be the richest man in Portugal, having accumulated two duchies and numerous lordships. [1] [2] In 1472, when his older brother John, Duke of Viseu, died without issue, Diogo inherited his titles and estates as Duke of Viseu and Duke of Beja.
Diogo was a popular personality at the court of his cousin King John II, and together with Duke Fernando II of Braganza, he was the main target of King John's centralization policies. [3] John II sought to limit the power of the upper nobility, which had increased greatly during the reign of John's father Afonso V of Portugal. [2] [4] [5]
Duke Fernando II of Braganza, husband of Isabella of Viseu, the sister-in-law of King John II of Portugal and Diogo's sister, was the first victim of John's efforts against the Portuguese nobility. In 1483, he was imprisoned, tried and executed in Évora. [6] [7]
In 1484, Diogo was accused of being the center of a conspiracy against the crown and was stabbed to death by the king himself. [8] [9] [10]
After the execution, King John II called the duke's younger brother, Infante Manuel of Viseu, and showed him his brother's body. He promised Manuel that he would consider him his own son. At that moment, Manuel inherited his brother Diogo's titles and estates. [11] [12]
Duke Diogo never married, but when he was quite young he visited the Crown of Castile, where he had a love affair with Doña Leonor de Sotomaior y Portugal (great-granddaughter of King Pedro I of Portugal). With her he had a natural son, Afonso de Portugal. King Manuel I of Portugal granted this nephew, Afonso de Portugal, the position of 8th Constable of Portugal. Afonso's daughter and heir, Beatrice of Lara, married the 3rd Marquis of Vila Real. [13]

Manuel I, known as the Fortunate, was King of Portugal from 1495 to 1521. A member of the House of Aviz, Manuel was Duke of Beja and Viseu prior to succeeding his cousin, John II of Portugal, as monarch. Manuel ruled over a period of intensive expansion of the Portuguese Empire owing to the numerous Portuguese discoveries made during his reign. His sponsorship of Vasco da Gama led to the Portuguese discovery of the sea route to India in 1498, resulting in the creation of the Portuguese India Armadas, which guaranteed Portugal's monopoly on the spice trade. Manuel began the Portuguese colonization of the Americas and Portuguese India, and oversaw the establishment of a vast trade empire across Africa and Asia.

As Sebastian and Henry lacked immediate heirs, a dynastic crisis unfolded, marked by internal conflicts and external contenders vying for the Portuguese throne. Ultimately, Philip II of Spain succeeded Henry I as King of Portugal, uniting the Portuguese and Spanish Crowns in the Iberian Union. This personal union endured for 60 years, during which the Portuguese Empire faced decline and global challenges, notably the Dutch–Portuguese War.

She married Afonso VI at the age of 20; because the marriage was never consummated, she was able to obtain an annulment. On 28 March 1668, she married the King's brother Infante Dom Peter, Duke of Beja, who was appointed prince regent the same year due to Afonso's perceived incompetence. She became queen a second time when Afonso died and Peter succeeded his brother, but she herself died three months later.
