Hadim Ibrahim Pasha

In 1551 he commissioned Court Architect (Turkish: Mimar) Sinan to erect his funerary mosque in Constantinople, in the neighborhood of the Gate of Silivri (Turkish: Silivrikapı).^[2] On January 21, 1562, he established an endowment (Turkish: Waqf), which was entitled to administer several institutions in the western part of Constantinople. These were: his Friday mosque with an elementary school in the Silivrikapı neighborhood ; another school near Silivrikapı; a Byzantine church which he had converted into a mosque, with an attached medrese and an elementary school (also erected by Sinan) near the Isakapı Gate;^[3] another elementary school near the Column of Arcadius and a water well for travellers outside Yenikapı Gate.^[2] The endowment was to be financed through villages donated by the Sultan, fields, shops and mills in Rumelia, and buildings in Edirne and Constantinople.^[2] The Waqf was administered by the Chief white eunuch of Topkapi.^[2] The location of these establishments in sparsely settled neighborhoods along the Walls, where the population was predominantly Christian, shows his desire of pursuing a policy of Islamization of the city.^[2]
