After her death, the rule of Granada continued under Yusuf I, who was later succeeded by his son Muhammad V. Under their stewardship, Granada would experience its peak.[37] Historian Brian A. Catlos attributed the dynasty's eventual success partly due to Fatima's "vision and constancy", especially during the turbulent reign of her brothers, son, and grandsons, which were marred by assassinations and the reigns of young monarchs.[37] Thanks to her lineage, Ismail and his descendants gained legitimacy even though they were not male-line descendants of Muhammad I.[13] Ismail's accession was the first instance of the throne passing to a ruler through the maternal line, which would happen again in 1432 with the accession of Yusuf IV. The rule of Fatima's descendants also started what historians call al-dawla al-isma'iliyya al-nasriyya, "the Nasrid dynasty of Ismail", a distinct branch of the dynasty from that of the previous Sultans.[25] Historian María Jesús Rubiera Mata compared her guardianship and tutelage of her grandsons to those of the contemporary María de Molina, who also played a central political role as regent of her son Ferdinand IV (1295–c. 1301) and grandson Alfonso XI of Castile (1312–1321).[28]
