Çandarlı Halil Pasha Çandarlı Halil Pasha ( died 1 June 1453 ) , also known as Çandarlı Halil Pasha the Younger ( to differentiate from his grandfather Çandarlı Kara Halil Hayreddin Pasha ) , was a highly influential Ottoman grand vizier under the sultans Murat II and , for the first few years of his reign , Mehmet II ( from 1439 to 1 June 1453 precisely ) . He was a member of the Çandarlı family , a highly influential political family in the Ottoman Empire . He is not to be confused with his grandfather , Çandarlı Kara Halil Hayreddin Pasha , whom he was named after and who had also served as grand vizier , under Murat I . Biography . Halil Pasha was the fourth and penultimate member of the Çandarlı family to hold the position of grand vizier in the Ottoman Empire . His father , Çandarlı Ibrahim Pasha the Elder , his uncle , Çandarlı Ali Pasha , and his grandfather Çandarlı Halil Pasha the Elder had also held the position in the past . His own son , Çandarlı Ibrahim Pasha the Younger , would also become grand vizier in the future . Twice during his reign , sultan Murat II , a man more interested in religion and the arts than politics , retired to the city of Manisa and Halil Pasha held effective control of the empire in the capital Edirne with Mehmet II , then still a child , as the nominal sultan . On both occasions , with the dangers presented by allied European armies attacking Ottoman territories , Çandarlı called back Murat II and deposed the young Mehmet II to replace him with his more capable father . These two incidents led to lasting resentment by Mehmet II towards Çandarlı . The fact that the Çandarlı family , which had become extremely wealthy from their influence in the empire for over a century , possibly more so than even the ruling Ottoman family itself , further strained tensions between Mehmet II and Halil Pasha , the scion of the Çandarlı family . When Mehmed II became sultan , the Byzantine emperor Constantine XI sent a messenger to the Ottomans , asking for an increase of the annuity of Orhan or otherwise to release him . Orhan was an distant Ottoman family member and could claim himself as pretender for the throne and potentially start a civil war . This strategy of disruption was used by the Byzantines several times before . Halil Pasha became infuriated at the message and replied to the messengers : In 1453 , one of the first acts committed by the ( then fully reigning ) Mehmed II immediately after the conquest of Constantinople was to execute Çandarlı Halil Pasha and confiscate his property . It is interesting to note that the city had been taken on 29 May 1453 and Halil Pasha ' s execution took place on 1 June 1453 , suggesting that this design had been premeditated by the sultan long ago . Mehmet II thus ended the Çandarlı era in the Ottoman Empire , and the later members of the family , whose descendants survive to the present day , became no more than provincial notables based in İznik , although they were to give yet another , short - term , grand vizier to the Ottoman Empire at the end of the 15th century ( Halil ' s son Çandarlı Ibrahim Pasha the Younger ) . Çandarlı Halil Pasha was , as such , the first Ottoman grand vizier to be executed by the sultan .
