Rashtrakuta dynasty
from the 8th to 10th century and the Indian Emperor Amoghavarsha of the Rashtrakuta Dynasty was described by the Arab traveller Sulaiman as one of the four great kings of the world. The medieval south Indian mathematician Mahāvīra lived in the Rashtrakuta dynasty and was the first Indian mathematician who separated astrology from mathematics and who wrote the earliest Indian text entirely devoted to mathematics. The greatest maritime Empire of the medieval Indians was the Chola dynasty. Under the great Indian Emperors Rajaraja Chola I and his successor Rajendra Chola I the Chola dynasty became a military, economic and cultural power in South Asia and South-East Asia. The power of the Chola empire was proclaimed to the eastern world by the expedition to the Ganges which Rajendra Chola I undertook and by the occupation of cities of the maritime empire of Srivijaya in Southeast Asia, as well as by the repeated embassies to China.
