1360 CE to 1371 CE
The seeds of some of the basic Ottoman imperial institutions are sown under Murad.
The administrative military offices of kaziasker (military judge), beylerbeyi (commander in chief), and grand vizier (chief minister) crystallize and are granted to persons outside the family of Osman, founder of the dynasty.
The origins of the Janissary (Yeniçeri; “New Force”) corps and the devshirme (child-levy) system through which the Janissaries are recruited are also traceable to Murad's reign.
The Kapikulu Corps, founded by Grand Vizier Chandarli Kara Halil and Kara Rüstem of Karaman during Murad's reign, are the Ottoman version of the Seljuq Ghulam Guards, founded by the Abbasids and in use since the eighth century.
“Kapi”, originally used as Kapu, means “The Gate” in Turkish but represents the Palace, while “Kapikulu” means “Palace Guard”.
