Some scholars state that the Bhakti movement's rapid spread in India in the 2nd millennium, was in part a response to the arrival of Islam and subsequent Islamic rule in India and Hindu-Muslim conflicts. This view is contested by some scholars, with Rekha Pande stating that singing ecstatic bhakti hymns in local language was a tradition in south India before Muhammad was born. According to Pande, the psychological impact of Muslim conquest may have initially contributed to community-style bhakti by Hindus. Yet other scholars state that Muslim invasions, their conquering of Hindu Bhakti temples in south India and seizure/melting of musical instruments such as cymbals from local people, was in part responsible for the later relocation or demise of singing Bhakti traditions in the 18th century.
