[3] The founding inscription at the Kirazli mosque dated 1436–37, commonly identified as the foundation of Şehabeddin, names his father "Abdullah".
Being hadim meant that he had access to the sultan's family which included his son known as Mehmed the Conqueror, in whom he might have planted the seed of thirst for expansion of the empire.
[7] Against the orders of Şehabeddin the Ottoman forces captured and garrisoned medieval fortress Žrnov, located on the highest top of Avala (in Serbia), and enforced its fortifications under the Pasha's direct supervision.
On 27 June 1441[10] forces under the command of Şehabeddin captured the mining district of Novo Brdo,[11] after having looted and burnt the town itself.
[15] In 1444 Şehabeddin appeared as commander of the forces that fought against Orhan, the challenger of the sultan's throne and again as beylerbey of Rumelia, in Varna.
[7] He died in 1453 in Bursa[16] after he had witnessed the success of the expansionist policy he has always been advocating when Ottomans captured Constantinople and executed his main rival Çandarlı Halil Pasha.
