The appointments have proved less than fruitful. Not only were they tyrants, but quasi-incompetent ones.
Assad and sons (Syria)
Hafez-al-Assad, president of Syria 1971-2000 made his son, the future president Bashar al-Assad his heir, and also propelled him through the army to the rank of Colonel in order to establish a power base. Bashar was also given responsibility for the 'Lebanon file', which managed the Syrian occupation of Lebanon.
Hussein and sons (Iraq)
Similarly Saddam Hussein gave first his son Uday, and then his son Qusay positions within the Iraqi hierarchy, specifically as commanders of the Fedayeen Saddam (the Ba'athist paramilitary force).
Mubarak and sons (Egypt)
Gamal Mubarak (above, left), son of former Egyptian president Hosni Mubarak, was also groomed to succeed his father, and was given a leading position within the structure of the ruling National Democratic Party.
Erdogan and son-in-law (Turkey)
In 2015 President Erdogan of Turkey also successfully pushed his prime minister to appointment of his son-in-law Berat Albayrak as energy minister.
When he was prime minister, Erdogan even brought Albayrak onto the pitch for an exhibition match at Basaksehir stadium.
