Leonor Teles de Menezes

Leonor Teles was queen consort of Portugal by marriage to King Ferdinand I, and one of the protagonists, along with her brothers and her daughter Beatrice, of the events that led to the succession crisis of 1383–1385, which culminated in the defeat of her son-in-law King John I of Castile and his armies in the Battle of Aljubarrota. Called "the Treacherous" by her subjects, who execrated her on account of her adultery and treason to her native country, she was dubbed by the historian Alexandre Herculano as "the Portuguese Lucrezia Borgia".
