In the earliest period Telugu literature existed in the form of inscriptions, precisely from 575 CE onward.
Prabandha Ratnavali (1918) & Pre-Nannayya Chandassu (Raja Raja Narendra Pattabhisekha Sanchika) by Veturi Prabhakara Sastry talk about the existence of Jain Telugu literature during 850-1000 CE. A verse from Telugu Jinendra Puranam by Pampa, a couple of verses from Telugu Adi Puranam by Sarvadeva and Kavijanasrayam by Malliya Rechana were all authored by Jain poet's and are the examples for Jain contribution to Telugu Literature.
Historically, Vemulawada was a Jain knowledge hub and played a significant role in patronizing Jain literature and poets. Excavations in the 1980s around Vemulawada revealed and affirmed the existence of Telugu Jain literature.
Malliya Rechana is considered to be the first Telugu Author. P.V.Parabrahma Sastry, Nidadavolu Venkata Rao, P.V.P Sastry also pointed out that many Jain works could have been destroyed. Historical rivalry among Hinduism, Jainism and Buddhism is well known.
