Harun ibn Khumarawayh

Harun ibn Khumarawayh (; died 30 December 904) was the fourth Tulunid vassal Emir of Egypt (896–904). He succeeded his elder brother Abu 'l-Asakir Jaysh, who had been murdered by army chiefs. He left state affairs to the vizier, Abu Ja'far ibn Ali, preferring to live a life of dissolute luxury. This led to a growing crisis in the country, since state finances could not be regulated and the army leaders gradually accrued more power to themselves
