That gate was named after a Zenata emir, 'Ajisa, who dominated the early city of "al-'Aliya" (on the Qarawiyyin side of the river), in rivalry with his brother, el-Fetouh, who dominated the city of "Madinat Fas" (now the Andalous quarter) on the opposite shore and who probably gave his name to another gate, Bab Ftouh.
