From the 14th century onwards, an overwhelming number of stone inscriptions in the Kathmandu Valley, where they are an ubiquitous element at heritage sites, are in Nepal Bhasa. The earliest dated stone inscription in Nepal Bhasa is dated Nepal Sambat 293 (1173 AD). The earliest known document in Newar is called "The Palmleaf from Uku Bahal" which dates from 1114 during the Thakuri period. The Newar language of Nepal has the fourth oldest literature tradition among the Sino-Tibetan languages (after Chinese, Tibetan and Burmese).

King Mahindra Malla (reigned 1560–1574) is regarded as the first Nepal Bhasa poet.
