The Banu Mazyad first acquired titles and subsidies from the Buyid emir Mu'izz al-Dawla in return for military services between 956 and 963.

At the establishment of the Seljuk Empire, Dubays threw his support behind the Shia Fatimid Caliphate and the general al-Basasiri.

[2] The reign of the weak Seljuk sultan Barkiyaruq (1092–1105) corresponds to the height of Sadaqa I's power.

After Malik-Shah II succeeded Barkiyaruq, he moved against Sadaqa, who was defeated and killed in battle in 1108.

His successor, Dubays II, was equally famous to the Latins and as an Arabic poet.
