Yusuf IV (Arabic: يوسف الرابع) (died 1432) was the sixteenth Nasrid ruler of Granada in Al-Andalus on the Iberian Peninsula in 1432.
A maternal grandson of Muhammad VI,[1] Yusuf IV was placed on the throne of Granada on 1 January 1432 with the support of the Catholic King John II of Castille, in return for tribute and vassal status.
However, the Castilian Catholic King John II did not decisively support either, instead playing them against each other to obtain greater tribute and the concession of Granada as a vassal of Castile.
John II continued to demand greater concessions, and would not offer a permanent peace.
[2] His son Aben Celim was the father of Cidi Hiaya Alnayar, later renamed Pedro de Granada, who married Cetimerien Venegas, later renamed María de Venegas, and had issue, including the Marquesses of Campotéjar[3] (including Alessandro Grimaldi, Doge of Genoa) and the Marquesses of Casablanca and the Lords of the Majorat of la Torre Marquesses of Torre Alta.
