After the death of Ibn Tulun , the army held a conference and appointed the son of Ibn Tulun , called Khumarawaih , ruler of
Egypt
.
Khumarawaih followed the same policy of his father and continued to attack El-Muwaffak in his orations and decided to invade Syria to defeat him . He sent a large army to Syria , while El Muwaffak went to Baghdad with his army , where some governors supported and provided him with equipment .
The two armies met near the Orontes River . After a short battle , Khumarawaih was defeated and returned to Egypt , leaving his army to finish the battle . Then , the remains of the Egyptian army succeeded in defeating the enemy . When the news reached Khumarawaih , he went to Syria again and entered Damascus . Then all of Khumarawaih , the Caliph , the son of the Caliph and the Caliph's brother , El-Muwaffak signed an agreement , according to which Khumarawaih became the governor of Egypt and Syria for about 30 years . After the victory of Khumarawaih and his agreement with the Caliph , he became the chief of Mosul and Barqa , Armenia , Tarsus and other cities .
Then , after a short time , the Caliph and
El-Muwaffak died and a new Caliph , called El Mo'tadid , ascended the throne . Khumarawaih sent him rich gifts and money . Therefore , the new Caliph extended the authority of Khumarawaih between Barqa and Euphrates , conditioning that "Khumarawaih should pay 300 , 000 dinars to the Caliph every year" .
The Caliph , El Mo'tadid , married the daughter of Khumarawaih who was called Qatr En-Nada . Khumarawaih spent 400 , 000 dinars on this marriage , paying a huge dowry and securing the way of his daughter to Baghdad .
After his death , the
Tulunid
Dynasty became very weak and the Caliph sent his army to enter Egypt .
