 This body of work included the early epics such as renditions of the "Dhola Maru" in the Marwari of Marwar, the "Prithviraj Raso" in the Braj Bhasha of Braj, and the works of Amir Khusrow in the dialect of Delhi.Modern Standard Hindi is based on the Delhi dialect, the vernacular of Delhi and the surrounding region, which came to replace earlier prestige dialects such as Awadhi, Maithili (sometimes regarded as separate from the Hindi dialect continuum) and Braj.
