محمد الثاني المهدي

فتنة قرطبة وخروج ابن عبد الجبار

The Cordoba fitna of 399–400: the Umayyad Muhammad ibn Hisham rose as 'al-Mahdi', hid the caliph Hisham al-Mu'ayyad and buried a Christian lookalike in his name; his uncle Hisham's counter-revolt failed, then Sulayman al-Musta'in marched in with Christian allies, won the great battle (35,000 dead), and took the bay'a while Berbers and Christians sacked the city.
