Hemachandra, one of Jainism's greatest scholars, was patronized by Jayasimha Siddharaja of the Chalukya dynasty. The Chalukya ruler supported Hemachandra's scholarly works including the Siddha-Hema-Shabdanushasana (grammar treatise) and various philosophical texts. This patronage enabled Hemachandra to make lasting contributions to Sanskrit literature, grammar, and Jain philosophy during the 12th century.
