Sultan declares Jihad

The fall of Tripoli prompted Sultan Muhammad Tapar to appoint the atabeg of Mosul, Mawdud, to wage jihad against the Franks. Between 1110 and 1113, Mawdud mounted four campaigns in Mesopotamia and Syria, but rivalry among his heterogeneous armies' commanders forced him to abandon the offensive on each occasion. As Edessa was Mosul's chief rival, Mawdud directed two campaigns against the city. They caused havoc, and the county's eastern region could never recover. The Syrian Muslim rulers saw the Sultan's intervention as a threat to their autonomy and collaborated with the Franks. After an assassin, likely a Nizari, murdered Mawdud, Muhammad Tapar dispatched two armies to Syria, but both campaigns failed.
