  Exploration in thE World of thE MiddlE agEs
inDia in the early miDDle ages
Another ancient and sophisticated Asian civilization was that of India. 
India, too, has many natural resources. Bordered to the north by the 
Himalayas, it has an extremely long coastline. By a.d. 500, Indian sailors 
were making good use of their access to the seas. e monsoon winds 
and currents of the Indian Ocean made for easy sailing.
India had a long tradition of science and advanced learning based 
on the Vedas, the ancient founding texts of Hinduism. Indian scholars 
led the world in astronomy and mathematics. Aryabhata the Elder was 
using  the  decimal  system  in  about  a.d.  500.  By  550,  Varahamihira 
had discovered zero. By the sixth century, Indian mathematicians had 
also created the symbols that are misleadingly called “Arabic” numer-
als. ese advances gave Indian sailors the tools to navigate in open 
seas 1,000 years before European sailors. By the early medieval period, 
India had long-established trade links throughout the Indian Ocean 
region. Sea routes connected India to Arabia, the Persian Gulf, Java, 
and Sumatra.
India also had overland routes to central Asia and the Middle East. 
ese routes were slower than the sea-lanes, but they were still popu-
lar. Buddhist missionaries from India reached China in the fourth cen-
tury. ey converted many Chinese from Daoism and Confucianism. 
e Chinese emperor banned Buddhism in the ninth century. By then, 
Buddhism had spread to the East Indies. A shared religion strengthened 
the trade links of this region with India.
Like China, India in the sixth century seemed ready to explore the 
wider world. But India, too, was subject to restraining factors. South 
Asia was divided into many kingdoms engaged in constant warfare. No 
single  kingdom  controlled  politics,  communications,  or  trade.  None 
were interested in conquering distant territories.
India’s people were not interested in exploration. Buddhism was a 
quiet, contemplative faith. Another native belief system, Hinduism, had 
intellectual traditions. Its reach never extended much beyond India. e 
ancient texts of  India  were written in Sanskrit, a  language  unknown 
outside of South Asia. Fortunately, the knowledge of Indian scholars, 
shipbuilders, and sailors was passed on to Arabs. e Arab traders were 
eager to  learn from Indian sailors and master the Indian  Ocean and 
reach the East Indies themselves.
