[3][4] Mamdouh Abbas graduated from the Faculty of Economics and Political Science, Cairo University in 1967, began his career as an employee of the Nasr Company for Export and Import, then turned to free work and established his first company in 1980, through which he worked in the field of trade, before developing his activities to include the fields of petroleum and information technology.

[7] Mamdouh Abbas founded the Kemet Boutros Boutros-Ghali Foundation for Peace and Knowledge with others and assumed the presidency of the board of trustees in 2018.

The decision included appointing Mamdouh Abbas as president of the Zamalek club, Hazem Abdel-Rahman Fawzi as vice-president, and Yahya Mustafa Kamal Helmy as treasurer.

[11] The Zamalek club presidency elections were held, during which Mortada Mansour and Mamdouh Abbas competed, and ended with Abbas winning the presidency of Zamalek Club, but Mansour insisted that the elections were rigged and rejected their results.

[10] On 20 December 2011, the Supreme Administrative Court decided to return Mamdouh Abbas to head the Zamalek club again after the end of his rivalry with Mortada Mansour, and in May 2013, Abbas's term ended, which prompted the Ministry of Sports to issue a decision to extend the council's work until the next elections in order to preserve the club's stability.
