Kapi Agha

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.

As his title implies, the Kapi Agha was in charge of the Gate of Felicity that separated the Outer Court (Birûn), where state affairs were conducted, from the Inner Court (Enderûn) and the Sultan's private apartments in the Topkapi Palace. The Agha occupied an office to the right of the gate and was responsible for controlling entrance to the Inner Court and for transmitting the Sultan's orders to his officials, rendering him, in the words of the Ottomanist Halil İnalcık "the sole mediator between the Sultan and the world outside the Palace". Among the duties of the Kapi Agha and his white eunuchs was also the running of the Palace School for the pages of the palace, whose graduates then went on to provide the administrative elite of the Empire. The "Mosque of the Aghas" (Ağalar Camii) in the Topkapi Palace was built for use by the Kapi Agha and his eunuchs.

The Kapi Agha consequently was an influential post, a close adviser to the Sultan and able to play a decisive role in the imperial succession. Its holders bore the rank of vizier and came in precedence only after the Grand Vizier and the Shaykh al-Islam. At his heyday in the 15th and 16th centuries, the Kapi Agha rivalled the Grand Vizier for importance. Nevertheless, and in contrast to his analogues in other Islamic states, usually denoted by variants of the title hajib, the holders of the office never expanded their power to the extent that they could rival the Sultan's own. Unlike their counterparts, the Kapi Aghas controlled neither the administrative apparatus, which remained firmly in the hands of the Grand Vizier, nor the palace troops, which were commanded by another official, the Agha of the Janissaries, who notably also received about five times the Kapi Agha's daily salary of 100 akçes. Nevertheless, many Kapi Aghas went on to assume major provincial governorships (often distinguished by the epithet hadım, "eunuch", in their subsequent careers), and several are considered as among the greatest Ottoman statesmen of the period.
