Aïcha al-Horra, generally known under her Spanish name Aixa (fl. 1493), was the spouse of Muhammed XI and of Abu l-Hasan Ali, and the mother of Muhammad XII. Aixa was also known by the Muslims as Aisha al-Horra (meaning the honored), due to the fact that she was one of the living descendants of the Prophet Muhammed. She was politically active and exerted influence upon the policy of state during the last years of the Emirate of Granada. Aixa is one of the best known women of the history of the Emirate of Granada.
Aixa was born a member of the ruling Nasrid dynasty of Granada, likely the daughter of Muhammed IX. She personally owned several palaces and properties. Aixa was first married to Muhammed XI; after his death in 1455, she was married by his successor Said to his heir, Abu l-Hasan Ali. Her second marriage was likely an attempt to make peace between the rival factions of the dynasty. Aixa was exiled to another palace with her sons after her spouse fell in love with his Christian slave Isabel de Solís and married her.
In 1482, Aixa allied herself with the opposition party Abencerrages and had her husband deposed in favour of her son. Aixa was politically active during the reign of her son Muhammed XII, also known as Boabdil. She is said to have prevented harassment of the Christians in Granada. In 1483, she handled the negotiations for the release of her son, who had been taken captive by the Castile. Aixa was known to be an extreme patriot, since she wanted to continue to fight to the death using women, children, and old men, even though the army of Granada was defeated by Ferdinand and Isabella of Castile and Aragon. She blamed the defeat on traitors in the kingdom who allowed themselves to betray their country for large sums of money and property if they would convince their king to surrender the Kingdom of Granada.
