The conversion of the Hagia Sophia into a mosque is one of the most critical points where the political and religious aims of Islamists and conservative nationalists intersect in Turkey.For both of them, Sultan Mehmet’s conquering Constantinople in 1453, renaming the city Istanbul, and converting of the Hagia Sophia—a symbolic house of worship for the Christian world—into a mosque marked the date when Islam and Turkishness began to collectively experience a golden age. It was during the aggressive secularisation of Turkey by Mustafa Kamal Pasha (Ataturk), that Hagia Sophia was converted into a museum. In our times, under the leadership of President Erdogan, a populist sentimental wave has been rising to convert the Hagia Sophia into a mosque. This is seen as an ascendency of Islam. It is unfortunate that such an act is not giving glory to Islam which strongly forbids Muslims from such a sacrilegious act. The conversion of Hagia Sophia will reopen the wounds of the Greek Orthodox Christians, Russian Orthodox Christians, and Christian communities across sectarian bounds around the world.
