This period encompasses two eras: Classical India, from the Maurya Empire up until the end of the Gupta Empire in the 6th century CE, and early Medieval India from the 6th century onwards. It also encompasses the era of classical Hinduism, which is dated from 200 BCE to 1100 CE. From 1 CE until 1000 CE, India's economy is estimated to have been the largest in the world, having between one-third and one-quarter of the world's wealth. It is followed by the late Medieval period in the 13th century.
