An Iranian-origin, Arabicized Muslim dynasty (Banu Saj) that governed Azerbaijan and parts of Armenia as a virtually independent Abbasid appanage, founded by Muhammad ibn Abi'l-Saj.
Dynasty ended with the death of Abu'l-Musafir al-Fath in 929; territory was absorbed into the successor Salarid/Musafirid sphere.
The atlas holds 2 border frames for Sajid dynasty — the shape you scrub through changes in 889 · 919.
Standard chronological/genealogical reference that carries a dedicated entry on the Sajids; no dedicated English-language monograph on the Sajids was found on Open Library, so this canonical manual is used as a well-justified fallback.
