Hoca Sadeddin Efendi

Hoca Sadeddin (or Sa'düddin) Efendi (1536 or 1537 – October 2, 1599) was an Ottoman scholar, official, and historian, a teacher of Ottoman sultan Murad III (when Murad was prince). His name is transcribed differently: Sa'd ad-Din, Sa'd al-Din, Sa’adeddin, Sadeddin, etc. He was also called "Hoca Efendi", "Koca Hoca Efendi" and with the title of "Câmi'-ür Riyâseteyn".

When Murad became Sultan, Sadeddin became his advisor. Later he fell out of favor, but was appointed Sheikh ul-islam, 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.
