Uma-maheshvara (IAST: Umāmaheśvara), also known as Abhinava-Kālidāsa ("the new Kalidasa"), was a Sanskrit-language philosopher and grammarian from present-day southern India.
Uma-maheshvara was born in a family belonging to the Vellala social group.
[2][3] According to the Rajashekhara-charita (or Shabharanjana-shataka) of his disciple Kavi-kunjara, Uma-maheshvara "put an end to the machinations" of Durjaya, the court poet of the Vijayanagara king Raja-shekhara.
P. Sriramamurti of Andhra University tentatively identifies the ruler as prince Raja-shekhara (the son of Deva Raya III), and on this basis, dates Uma-maheshvara to c. 1465 CE.
Ramanuja's followers Rangacharya (Ku-drishti-dhvanta-martanda) and Shrinivasa-dikshita (Virodha-varuthini-pramathini) wrote refutations of Uma-maheshvara's criticisms.
