Amoghavarsha

Amoghavarsha I (also known as Amoghavarsha Nrupatunga I) (r. 814 – 878 CE) was the greatest emperor of the Rashtrakuta dynasty, and one of the most notable monarchs of Early Medieval India. His reign of 64 years is one of the longest precisely dated monarchical reigns on record. Many Kannada and Sanskrit scholars prospered during his rule, including the great Indian mathematician Mahaviracharya who wrote Ganita-sara-samgraha, Jinasena, Virasena, Shakatayan and Sri Vijaya (a Kannada language theorist).^[1]
