Kizlar agha
The Kizlar Agha (Ottoman Turkish: قيزلر اغاسی, Turkish: kızlar ağası, lit. '"agha of the girls"'), formally the Agha of the House of Felicity (Ottoman Turkish: دار السعاده اغاسي, Turkish: Darüssaade Ağası), was the head of the eunuchs who guarded the Ottoman Imperial Harem in Constantinople. Established in 1574, the post ranked among the most important in the Ottoman Empire until the early 19th century, especially after the stewardship of the two holy cities of Mecca and Medina and the supervision of all waqfs (charitable foundations) in the Empire came under his purview.
