El Zaher ibn El Hakim was the only son of El-Hakim . He was about 16 years old when his father was killed; therefore , he was put under the regency of his aunt , Sayyedat El-Mulk .
After the death of his aunt , the government fell in the hands of some very bad high officials , who encouraged the young Caliph to be lazy and careless .
The level of the Nile decreased; the prices of the products became very high , and the common meat came unavailable; thus , many people died because of the lack of food . The treasury became empty and the royal palace itself suffered from the lack of food and , therefore , a famine happened during his reign . But , this famine decreased by the increasing of the Nile level .
