The Saving Intervention: Hadım Ali Pasha

Although the Church of Chora managed to survive the conquest of Constantinople in 1453 without major damage, the passage of time and the lack of use as a primary temple threatened its structure.

It was the Vizier Hadım Ali Pasha (also known as Atik Ali Pasha), Grand Vizier to Sultan Bayezid II, who ensured its historical permanence.

· The Act of Preservation: In 1511, Hadım Ali Pasha decided to convert the church into a mosque, giving it the name Kariye Camii. In the Ottoman tradition, the conversion of a large building into a mosque was an act of piety and a means of structural and functional preservation.

· The Paradox of Conservation: Ironically, the act of converting it into a mosque required covering the mosaics and frescoes with plaster or wooden shutters, as the depiction of human figures is prohibited in Islamic prayer spaces. However, this covering functioned as a protective layer, shielding the delicate murals from humidity, vandalism, and environmental deterioration for nearly four centuries.

· Additional Legacy: In addition to the conversion, Hadım Ali Pasha founded a külliye complex (a service complex) around the new mosque, adding a madrasa (theological school) and a charity kitchen, thus solidifying the site’s status as a vital social and religious center in the area.

Thanks to Hadım Ali Pasha’s decision, what could have fallen into neglect and ruin, as happened with other minor temples, was preserved as a structural jewel that, centuries later, could reveal its Byzantine treasures intact.

Who Was Hadım Ali Pasha? A Statesman and Preserver

Ali Pasha was one of the most influential political figures in the Ottoman Empire during the late 15th and early 16th centuries. Of Bosnian origin, he was trained in the rigorous Devşirme system and rose through the ranks due to his skill and loyalty.

· Power and Rank: The epithet “Hadım” (meaning “eunuch”) denotes his key position as a high-ranking official with immense authority within the Imperial Palace. He held positions of great responsibility, including Kapudan Pasha (Admiral of the Fleet) and, crucially, served as Grand Vizier (the Sultan’s chief executive minister) of the Ottoman Empire on two occasions during the reign of Bayezid II.

· Patronage and Piety: As was customary among elite Ottoman statesmen, Ali Pasha used his considerable wealth for pious and public charity works, known as waqf (endowment foundations). His decision regarding Chora was part of his waqf and one of his most lasting contributions to Istanbul.

The Act of Conversion and Legacy

The fact that a man with the power of a Grand Vizier focused on the Church of Chora in 1511 ensured that the building received the necessary funding and attention for its survival.

· Conversion to Kariye Camii: Ali Pasha decided to convert the church into a mosque. This act not only fulfilled a religious duty but, in the Ottoman tradition, was the most effective means for the structural and functional preservation of a large building, ensuring its continuous maintenance.

· The Protective Paradox: Ironically, the conversion required the mosaics and frescoes to be covered. This covering functioned as a vital protective layer, shielding the delicate murals from humidity, vandalism, and environmental deterioration for nearly four centuries.

· Social Foundation: Ali Pasha cemented the site’s importance by founding a külliye complex (a service complex) around the new mosque, adding a madrasa (theological school) and a charity kitchen (imaret), consolidating the building as a vital social and religious center.

Thanks to this intervention, what could have succumbed to ruin was preserved as a structural jewel that, centuries later, could reveal its intact Palaiologan Renaissance treasures.

Hadım Ali Pasha passed away on July 5, 1511, during the Battle of Küpe. At that time, he was serving as the Grand Vizier and was leading the forces of Sultan Bayezid II against the Safavid rebels (supporters of Shah Ismail I) in Anatolia.

During the engagement, Hadım Ali Pasha was severely wounded and died of his injuries on the battlefield. His death occurred shortly after he secured the conversion and preservation of the Church of Chora (Kariye Camii) earlier that same year, which underscores his importance and activity until the end of his life.
