Al-Bayān wa’l-iʿrāb ʿammā fī arḍ Miṣr min al-aʿrāb 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-Maqrīzī’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.
