This document provides an overview of the Indian economy through history and to the present day. It discusses:
1) India's economy through ancient civilizations like the Indus Valley and periods under the Mughal Empire when it accounted for 25% of global GDP.
2) The impact of British colonial rule from 1793-1947, which caused India's economy to decline and left it poorly industrialized.
3) Post-independence policies from 1947-1991 that focused on import substitution, a large public sector, and business regulation.
