 Nasr on the other hand, in addition to his other qualities, was a Mudari and married to a Tamimi wife. He would therefore be acceptable to the numerous Mudari element of the Khurasani army, which outnumbered the Yemenis, but could also, as a local, help to reduce the Khurasani Arabs'discontent towards the Syria-centric Umayyad government. Nasr's own relatively obscure tribal background — from a non-noble family of the Layth tribe from Kinanah — also suited the Caliph's purposes, as it meant that he lacked any local power base of his own. Indeed, Nasr's rule throughout his tenure was not fully accepted by many Arab tribesmen: aside from the Yemenis, who favoured their "own" candidate al-Kirmani and resented the shift in power back towards the Mudaris, the Qays around Nishapur refused to support him, and even the Syrian contingent sided with his opponents. Nasr was hence mostly reliant on the support of his wife's powerful Tamim tribe living around Marv. As long as he was supported by a strong central government in Damascus, Nasr was able to keep his internal enemies in check, but in the troubles that followed Hisham's death in 743, that support vanished. In the event, Nasr would succeed in retaining his office for a decade, despite the turmoil that swept the Caliphate after 743. When Yazid III came to power in early 744, he initially ordered Nasr replaced. Nasr refused to accept this, and held on to the post, being eventually confirmed to it a few months later. After Marwan II's rise to power in December 744, he likewise affirmed Nasr's position.
