Book of Clear Arabic Expression regarding the Arab Tribes of Egypt

Al-Bay?n wa'l-i?r?b ?amm? f? ar? Mi?r min al-a?r?b is an influential treatise on the Arab and Berber groups that inhabited the Egyptian countryside in the late medieval period. The work brings together al-Maqr?z?'s life-long preoccupation with the history of Egypt and his parallel interest in the history of the Arabs, pitting the lineage-based ideology of Arab rebels against the Mamluk elite of manumitted slaves.
