Some of these tombs became the focus of entire religious complexes built around them, known as a "zawiya" (also spelled "zaouia"; ). They typically included a mosque, school, and other charitable facilities. Such religious establishments were major centers of Moroccan Sufism and grew in power and influence over the centuries, often associated with specific Sufi Brotherhoods or schools of thought. The Saadian dynasty, for example, began as a military force associated with the zawiya and followers of Muhammad al-Jazuli, a major 15th-century Sufi scholar. The Alaouites after them also sponsored many zawiyas across the country. Some of the most important examples of zawiyas in Morocco include the Zawiya of Moulay Idris I near Meknes, the Zawiya of his son Moulay Idris II in Fes, and the tombs of the Seven Saints in Marrakesh.
