Moulay Ismail Ibn Sharif, born around 1645 in Sijilmassa and died on 22 March 1727 at Meknes, was a Sultan of Morocco from 1672 to 1727, as the second ruler of the 'Alawi dynasty. He was the seventh son of Moulay Sharif and was governor of the province of Fez and the north of Morocco from 1667 until the death of his half-brother, Sultan Moulay Rashid in 1672. He was proclaimed sultan at Fez, but spent several years in conflict with his nephew Moulay Ahmed ben Mehrez, who also claimed the throne, until the latter's death in 1687. Moulay Ismail's 55-year reign is the longest of any sultan of Morocco. During his lifetime, Isma’il amassed a harem of over 500 women with more than 800 confirmed biological children, making him one of the most prodigious fathers in recorded history.

Sijilmasa was a medieval Moroccan city and trade entrepôt at the northern edge of the Sahara in Morocco. The ruins of the town extend for five miles along the River Ziz in the Tafilalt oasis near the town of Rissani. The town's history was marked by several successive invasions by Berber dynasties. Up until the 14th century, as the northern terminus for the western trans-Sahara trade route, it was one of the most important trade centres in the Maghreb during the Middle Ages.
