What is "manasir"

The Manasir people constitute one of many Sunni Arab riverine tribes of Northern Sudan. They are not to be confused with the Al Manaseer of the Gulf region in the Arabian Peninsula-based mainly in the United Arab Emirates. They inhabit the region of the Fourth Cataract of the Nile and call their homeland Dar al-Manasir. Similar to their neighbouring tribes, the upstream Rubatab (الرباطاب) and the downstream Shaiqiyah (الشايقيّة), the Manasir are an indigenous Nile culture who adapted Islam and became Arabic speakers. Unlike other riverine tribes of the Sudan, a considerable part of their population lives as Bedouins in the adjacent Bayudah Desert. The nomadic life of herding their stock of goats, sheep and camels in desert valleys is however limited for many to the rainy season, coinciding with the annual inundation of the Nile.
