Al-Mawardi — Abbasid Chief Justice, Author of al-Ahkam al-Sultaniyya (the First Systematic Theory of the Islamic State), and the Scholar Who Defined the Conditions for a Valid Imam-Caliph at the Very Moment the Abbasid Caliphate Was Becoming a Purely Ceremonial Office

Al-Mawardi (المَاوَرْدِيّ; full name: Abu al-Hasan Ali ibn Muhammad ibn Habib al-Mawardi al-Basri; born 364 AH / 974 CE in Basra; died 450 AH / 1058 CE in Baghdad; grew up in Basra; studied fiqh under Abu al-Qasim al-Saymari [a student of Abu Hamid al-Isfara'ini] and traveled to Baghdad; the Shafi'i school: al-Mawardi was a leading Shafi'i jurist of his era; the Abbasid appointment: the Abbasid caliph al-Qadir Billah and later al-Qa'im bi-Amr Allah appointed al-Mawardi to the position of Qadi al-Qudat [Chief Justice]; he was also used as a diplomatic envoy by the Abbasids in negotiations with the Buyid sultans — who effectively held real political power while the Abbasid caliphs maintained ceremonial authority; the irony of his life: al-Mawardi wrote the most comprehensive theory of legitimate Islamic governance at precisely the moment when the Abbasid caliphate had been stripped of real power; his theoretical framework was responding to — or perhaps attempting to restore — a reality that had already dissolved; major works: [1] al-Ahkam al-Sultaniyya [The Ordinances of Government]: the first systematic treatise on Islamic public law; covers: the conditions for a valid caliph [7 conditions including Qurayshi lineage, justice, knowledge, physical/mental capacity, military competence, administrative judgment]; the appointment procedure [election by ahl al-hall wal-'aqd or designation by the previous caliph]; the offices of state [wazarat, amirat, qada', shurta, hisba]; taxation; public administration; [2] Adab al-Dunya wal-Din [The Conduct of Worldly and Religious Affairs]: a popular manual on personal ethics and social conduct, his most widely read work in subsequent centuries; [3] Al-Hawi al-Kabir [The Grand Compendium]: an enormous fiqh encyclopedia in the Shafi'i tradition, reportedly 20 volumes; the theory of necessity [darura]: al-Mawardi's discussion of what happens when a caliph falls short of the conditions [e.g., loses physical capacity or becomes politically dominated] laid the groundwork for later 'theory of necessity' doctrines that accepted sub-ideal leaders as valid; the Qurayshi lineage requirement: al-Mawardi required the caliph to be from Quraysh [the Prophet's tribe]; this would increasingly become a theoretical requirement ignored in practice; modern relevance: al-Ahkam al-Sultaniyya is still taught in Islamic law curricula and cited in debates about Islamic governance, constitutionalism, and the caliphate's legitimacy) is the Islamic political theorist par excellence.
