 There he sent a delegation to the Aghlabid court, which pleaded with the Aghlabid emir Ziyadat Allah for an army to help Euphemius conquer Sicily, after which he would pay the Aghlabids an annual tribute.This offer came as a great opportunity for the Aghlabids, who faced long-simmering ethnic tensions between Arab settlers and Berbers, dissension and rebellions within the Arab ruling elite (the "jund"), and criticism for their preoccupation with worldly concerns, their "un-Islamic" system of taxation and their luxurious lifestyle from the jurists of the Malikite school.Indeed, at the time of Euphemius' arrival, Ziyadat Allah had just suppressed a dangerous three-year revolt of the "jund" under Mansur al-Tunbudhi.
