Manuel I of Portugal
Manuel's mother was the granddaughter of King John I of Portugal, whereas his father was the second surviving son of King Edward of Portugal and the younger brother of King Afonso V of Portugal. In 1495, Manuel succeeded his first cousin, King John II of Portugal, who was also his brother-in-law, as husband to Manuel's sister, Eleanor of Viseu.
Postage stamps and postal history of the Niassa Company
After the assassination of King Carlos I in 1908 his son, Manuel, ascended to the throne for two turbulent years until deposed following the 1910 revolution. Nyassa's stamps were belatedly updated by the creation of an issue in 1911 (pictured in the gallery below) based on a similar layout to the 1901 issue, but featuring two new designs (a zebra and the St. Gabriel, the flagship of Vasco da Gama's fleet), Manuel's portrait in place of that of Carlos I, and overprinted in red with the word "REPUBLICA" to reflect Portugal's new political status.
