[1] After the Battle of Poitiers (732), Yusuf ibn Abd al-Rahman was appointed governor of Narbonne according to the Chronicle of Moissac, where he was in command of military operations.
However, after taking over and completing his term, he refused to give up the reins of power, ruling unchallenged for nine years, while in Damascus the Umayyads were definitively overthrown in 750.
On Abd al-Rahman's arrival, Andalusian forces were divided, with both commanders claiming the allegiance of both Berbers and the Syrian junds.
Generally, Yemeni units within the latter joined the Umayyad contender, while their Mudar and Qays rivals remained loyal to Yusuf.
Still Yusuf managed to flee the battlefield north and make his way towards Toledo, possibly first attempting to recapture Seville, but failing.
