Seraglio in the context of "Belmont und Constanze, oder Die Entführung aus dem Serail"

The Topkapı Palace or the Seraglio, is a large museum and library in the east of the Fatih district of Istanbul in Turkey. From the 1460s to the completion of Dolmabahçe Palace in 1856, it served as the administrative center of the Ottoman Empire, and was the main residence of its sultans.

Construction, ordered by the Sultan Mehmed the Conqueror, began in 1459, six years after the conquest of Constantinople. Topkapı was originally called the "New Palace" (Yeni Saray or Saray-ı Cedîd-i Âmire) to distinguish it from the Old Palace (Eski Saray or Sarây-ı Atîk-i Âmire) in Beyazıt Square. It was given the name Topkapı, meaning Cannon Gate, in the 19th century. The complex expanded over the centuries, with major renovations after the 1509 earthquake and the 1665 fire. The palace complex consists of four main courtyards and many smaller buildings. Female members of the Sultan's family lived in the harem, and leading state officials, including the Grand Vizier, held meetings in the Imperial Council building.

The Ottoman Imperial Harem (Ottoman Turkish: حرم همايون, romanized: Harem-i Hümâyûn, lit. 'Imperial Harem') of the Ottoman Empire was the Ottoman sultan's harem – composed of the wives, servants (both female slaves and eunuchs), female relatives and the sultan's concubines – occupying a secluded portion (seraglio) of the Ottoman imperial household. This institution played an important social function within the Ottoman court, and wielded considerable political authority in Ottoman affairs, especially during the long period known as the Sultanate of Women (approximately 1534 to 1683).

Historians claim that the sultan was frequently lobbied by harem members of different ethnic or religious backgrounds to influence the geography of the Ottoman wars of conquest. The utmost authority in the imperial harem, the valide sultan, ruled over the other women in the household. The consorts of the sultan were normally of slave origin, including the valide sultan.

Die Entführung aus dem Serail (German: [diː ʔɛntˈfyːʁʊŋ ʔaʊs dɛm zeˈʁaɪ]) (K. 384; The Abduction from the Seraglio; also known as Il Seraglio) is a singspiel in three acts by Wolfgang Amadeus Mozart. The German libretto is by Gottlieb Stephanie, based on Christoph Friedrich Bretzner's Belmont und Constanze, oder Die Entführung aus dem Serail. The plot concerns the attempt of the hero Belmonte, assisted by his servant Pedrillo, to rescue his beloved Constanze from the seraglio of Pasha Selim. The work premiered on 16 July 1782 at the Vienna Burgtheater, with the composer conducting.

The Kapi Agha (Turkish: Kapı ağası, "Agha of the Gate"), formally called the Agha of the Gate of Felicity (Bâbüssaâde ağası), was the head of the eunuch servants of the Ottoman Seraglio until the late 16th century, when this post was taken over by the Kizlar Agha. In juxtaposition with the latter office, also known as the Chief Black Eunuch as its holders were drawn from Black African slaves, the Kapi Agha is also known as the Chief White Eunuch.
