The Battle of Oujda occurred when the Almohad Caliph, supported by the Marinids, directed an offensive against the Zayyanids.

[1][2] The Almohad Caliph Abu al-Hasan as-Said al-Mutadid had set up camp and invited Yaghmurasen to submit to him and recognise him as his overlord.

The death of Caliph Abu al-Hasan as-Said al-Mutadid caused the dispersal of the Almohad besiegers.

In an alternative version, Yaghmurasen out of respect for the caliphal dignity dismounts and expresses his regrets.

[1][2][3][4] The victory enhanced the prestige of Yaghmurasen who then only held the title of amir al muslimin.
