Page "Zawiya (institution)" Paragraph 6

Often, the Zawiya tended to be descended from Sanhadja Berbers, while the Hassane claimed lineage from the Beni Hassan Arabs.

Even if intermarriage and tribal alliances made the distinction difficult to maintain from a scientific perspective, it was culturally important ; however, from about the 19th century, most or all Sahrawi-Moorish tribes had adopted the Hassaniyya Arabic dialect and come to regard themselves as Arabs.

Sometimes, the Zawiya and Hassane roles changed with this: military and economic strength would often lead to a gradual redefinition of the tribe's role, and, simultaneously, to its self-perception of religious and ethnic background.

Especially in the northern Hassane areas, i. e. today's Western Sahara, the Zawiya tribes were more or less synonymous with the Chorfa, tribes who claimed descent from the Prophet Muhammad.

In the areas corresponding broadly to today's Mauritania, this was not necessarily so ; there, the name " Marabout " is also used synonymously with " Zawiya " in its tribal meaning.
