Moussem of Moulay Idriss al-Akbar (Zerhoun)

The Moussem of Moulay Idriss al-Akbar is the largest saint's festival in Morocco. It takes place at the mausoleum of Idris I in the town of Moulay Idriss Zerhoun, which is situated on two hills at the foot of Jbel Zerhoun and overlooks the Roman ruins of Volubilis (Walili), approximately 30 km north of Meknes. Idris I, a descendant of the Prophet Muhammad, fled west after the Battle of Fakhkh in 786 and was welcomed by the Awraba nation-group at Walili. He established the Idrisid dynasty, the first Muslim state in Morocco, and is buried in the town that bears his name. The town itself is small, with about 11,600 residents, but the festival transforms it completely.

Every year, tens of thousands of pilgrims flock to the town, significantly outnumbering its residents and revitalising the local economy. Sufi brotherhoods and trade organisations also come to seek the saint's blessing (baraka). For many Moroccans who cannot travel to Mecca, this visit serves as a spiritual alternative, and the moussem is often referred to as the "pilgrimage of the poor" (in scholarship, Hajj al-Miskin).

The term "moussem" comes from the Arabic word "mawsim," meaning "season," and this gathering occurs in the post-harvest late summer, lasting for over a month.

A parallel moussem honours Idris II, the son of Idris I and the patron saint of Fez, at his zawiya in the heart of Fes el-Bali. Idris II established Fez as his capital in 808-809, on the opposite bank of an earlier settlement his father had begun around 789.

The Fez moussem occurs later in the year, in late September or early October, and lasts about a week. Both events maintain a similar devotional character, featuring processions of guilds through the medina, prayers at the tomb, Sufi music, and nightly vigils.

After the Battle of Fakhkh in 786, Idris ibn Abdallah fled to the Maghreb and married Kenza al-Awrabiya in Walili, where he was recognised as imam. He died in 791, allegedly poisoned by the Abbasid caliph Harun al-Rashid. His son, Idris II, was born posthumously and took leadership around 803, establishing Fez as his capital in 808-809.

The cult of the Idrisid founders faded after the 10th century, was suppressed by the Almoravids, and later revived by the Marinids from the 14th century. The rediscovery of Idris I's remains in Zerhoun is dated to 1318, while Idris II's tomb in Fez was rediscovered in 1437. The Saadian and Alaouite dynasties, claiming descent from the Prophet, elevated both figures for legitimacy, with Alaouite sultan Moulay Ismail rebuilding the Zerhoun mausoleum between 1719 and 1721.

Pilgrims visit Moulay Idriss's tomb, participate in processions, and enjoy music and dance.
