Harsha, who was a successor of the Guptas, quickly moved to reestablish an Indian empire. From 606-647, he ruled over an empire in northern India. Harsha was perhaps one of the greatest conquerors of Indian history, and unlike all of his conquering predecessors, he was a brilliant administrator. He was also a great patron of culture. His capital city, Kanauj, extended for four or five miles along the Ganges River and was filled with magnificent buildings. Only one-fourth of the taxes he collected went to administration of the government. The remainder went to charity, rewards, and especially to culture: art, literature, music, and religion
