Abu Abdallah Muhammad IV al-Thabiti

Abu Abdallah Muhammad IV, known as Al-Thabiti, ruled the Kingdom of Tlemcen for thirty-six years from 1468 until 1504. His reign represented one of the most culturally luminous chapters in late medieval Algerian history, coinciding with the tragic fall of the Emirate of Granada in 1492.

Al-Thabiti opened the gates of Tlemcen, Oran, and Mostaganem to thousands of exiled Andalusian artisans, jurists, musicians, and Jewish traders, assimilating their sophisticated urban traditions into Algerian culture. He commissioned the court chronicler Muhammad ibn Abdallah al-Tanasi to write 'Nazm al-Durr', preserving the official history of the Zayyanid dynasty.
