Eleanor of Viseu

Eleanor of Viseu (2 May 1458 – 17 November 1525; ) was a Portuguese infanta (princess) and later queen consort of Portugal. She is considered one of her country's most notable queens consort and one of the only two who were not foreigners. To distinguish her from other infantas of the same name, she is commonly known as Eleanor of Viseu (after her father's title) or Eleanor of Lancaster (Lancaster, a name used by some Portuguese royals after her great-grandmother Queen Philippa of Lancaster). In Portugal, she is known universally as Rainha Dona Leonor. Family Eleanor was a daughter of Infante Fernando, Duke of Viseu, and his wife and cousin Beatrice of Portugal. Her maternal grandparents were Infante João of Portugal and his wife and niece Isabel of Barcelos. Eleanor's sister Isabel of Viseu married Fernando II of Braganza, who was later accused and executed of treason by Eleanor's husband King John II. Eleanor's older brother Diogo, Duke of Viseu, was also involved in activities that John II considered treasonous and was executed by the king himself. Her younger brother succeeded John II as King Manuel I of Portugal. Marriage
