Hoysala literature is the large body of literature in the Kannada and Sanskrit languages produced by the Hoysala Empire (1025–1343) in what is now southern India. Kannada literature during this period consisted of writings relating to the socio-religious developments of the Jain and Veerashaiva faiths, and to a lesser extent that of the Vaishnava faith. The earliest well-known brahmin writers in Kannada were from the Hoysala court. While most of the courtly textual production was in Kannada, an important corpus of monastic Vaishnava literature relating to Dvaita (dualistic) philosophy was written by the renowned philosopher Madhvacharya in Sanskrit. Writing Kannada literature in native metres was first popularised by the court poets. These metres were the sangatya, compositions sung to the accompaniment of a musical instrument; shatpadi, six-line verses; ragale, lyrical compositions in blank verse; and tripadi, three-line verses. However, Jain writers continued to use the traditional champu, composed of prose and verse. Important literary contributions in Kannada were made not only by court poets but also by noblemen, commanders, ministers, ascetics and saints associated with monasteries.
