With this victory, the Almoravid Emir was bestowed with unrivalled prestige and authority. Consequently, the battle of al-Zallāka is celebrated by all Arab authors as an epic and redeeming event. Its hero, Yūsuf ibn Tāshfin, exalted and transcendent, is seen as a providential man, come to return power, moral and military splendour to an offended Islam. But shortly afterwards, he had to return in haste to Africa, leaving a large part of his troops in Seville. On his return to Morocco, he tried to consolidate his control over the trans-Saharan trade networks. He established a new army, reinforced with black troops and European mercenaries. Once his hegemony was assured across the kingdoms of Maghreb and Ghana, he once again took the road to Al -Andalus, first in $481 \mathrm{AH} / 1088$ CE, then in $483 \mathrm{AH} / 1090$ CE. After seizing Grenada, Malaga, Seville, Cordoba, Badajoz, Almeria and Valencia, he established himself as the absolute monarch of a vast Euro-African empire extending from the Senegal River to Andalusia (Ibn Khaldūn, op. cit., vol. VII, pp. 127-8).
