It was built by the Mughal emperor Shah Jahan between 1644 and 1656, and inaugurated by its first Imam, Syed Abdul Ghafoor Shah Bukhari. Situated in the Mughal capital of Shahjahanabad (today Old Delhi), it served as the imperial mosque of the Mughal emperors until the demise of the empire in 1857. The Jama Masjid was regarded as a symbolic gesture of Islamic power across India, well into the colonial era. It was also a site of political significance during several key periods of British rule. It remains in active use, and is one of Delhi's most iconic sites, closely identified with the ethos of Old Delhi.
