Demolition of the Babri Masjid
The Babri Masjid, a 16th-century mosque in the Indian city of Ayodhya, was destroyed on 6 December 1992 by a large group of activists of the Vishva Hindu Parishad and allied organisations. The mosque had been the subject of a lengthy socio-political dispute, and was targeted after a political rally organised by Hindu nationalist organisations turned violent.
