The Sajid dynasty is an Islamic dynasty that rules Azerbaijan from 889-890 until 929.

Sajids rule Azerbaijan and Armenia first from Maragha and Barda and then from Ardabil.

The Sajids originate from the Central Asian province of Ushrusana and are of Iranian (Sogdian) descent.

Muhammad ibn Abi'l-Saj Diwdad the son of Diwdad, the first Sajid ruler of Azerbaijan, is appointed as its ruler in 889 or 890.

Muhammad's father Abi'l-Saj Devdad had fought under the Ushrusanan prince Afshin Khaydar during the latter's final campaign against the rebel Babak Khorramdin in Azerbaijan, and later served the caliphs.

Toward the end of the 9th century, as the central authority of the Abbasid Caliphate weakened, Muhammad is able to form a virtually independent state.

Much of the Sajids' energies are spent in attempting to take control of neighboring Armenia.

The dynasty ends with the death of Abu'l-Musafir al-Fath in 929.
