The "language of Braj" is a medieval Hindi dialect spoken mainly in the Braj area, south of modern-day Delhi.
Braj is the region of Krishna, and the devotion that thrived there between the fifteenth and eighteenth centuries helped to establish Braj Bhasha as a significant literary language.
Apart from being the language of Krishna followers, it also served as a lingua franca—a common language spoken by a wide range of people—for religious adherents (bhakta) throughout a much wider region of northern India, but dialects differed at the boundaries.
