Madragana Ben Aloandro, later Maior or Mór Afonso (Faro, Algarve, Portugal, born c. 1230), was a woman from the Algarve known as a mistress to king Afonso III of Portugal, in the 13th century, when he ended the Reconquista in Portugal by taking Faro in 1249. Faro was at that time the last part of the Kingdom of the Algarve still in Muslim hands, and there her father was the Qadi.
She was christened in time, receiving her new name as Maior Afonso, or Mor Afonso, Mor being short for Maior, a common female name in medieval Portuguese. Afonso was given her in baptism as her new patronymic, meaning "the daughter of" Afonso - and that suggests that her elderly royal lover was also her godfather, that she took his spiritual "fatherhood" when christened. Her father's name was Aloandro Ben Bekar (also known in Portuguese as Aloandro or Aldroando Gil after his christening).
In ancient Portuguese chronicles, Madragana was also referred to as Mouroana,Mouroana Gil, and Madraganil - all of which are Christian names.
There is some controversy regarding her ethnicity. , a Portuguese royal chronicler of the 16th century, said that Madragana was a Moor. That was denied in the 18th century by , in which he is followed by many modern authors. She was likely Mozarab. Nonetheless, this supposed Moorish connection gave rise to a claim that the royal family of England had African ancestry via the 15-generation descent of Queen Charlotte of Mecklenburg-Strelitz, wife of George III of the United Kingdom, from Madragana, giving the Queen what the proponent described as the appearance of a 'mulatto'. However, it is far from clear that Madragana's family was of negroid origin, nor is it likely that were she African, Madragana's negligible contibution to Charlotte's genetic makeup would have caused the Queen alone, among all of Madgarana's descendants at this distant time including her husband and most of the royalty of Europe, to display distinctive African features.
