Pallava dynasty
Vijayalaya was the founder of the Imperial Chola dynasty which was the beginning of one of the most splendid empires in Indian history. Vijayalaya, possibly a feudatory of the Pallava dynasty, took an opportunity arising out of a conflict between the Pandya dynasty and Pallava dynasty in c. 850, captured Thanjavur from Muttarayar, and established the imperial line of the medieval Chola Dynasty. Thanjavur became the capital of the Imperial Chola Dynasty.
