Hoca Sadeddin Efendi

Hoca Sadeddin Efendi (; 1536/1537 – October 2, 1599) was an Ottoman Islamic scholar, theologian, official, and historian, a teacher of the future Ottoman sultan Murad III. His name may be transcribed variously, e.g. Sa'd ad-Din, Sa'd al-Din, Sa'düddin, or others. He was also called by the title of "Câmi'-ür Riyâseteyn". When Murad became Sultan, Sadeddin became his advisor. Later he fell out of favor, but was appointed Shaykh al-Islām, a superior authority in the issues of Islam. Sadeddin is the author of Tâc üt-Tevârîh (Tadj ut-Tewarikh, “Crown of Histories”), a history of the Ottoman Empire in prose and verse. He had at least five sons: Mehmed Efendi (died 1615), Esad Efendi (died 1625), Mesud Efendi (died 1597), Abdülaziz Efendi (died 1618), and Salih Efendi.
