Economic history of India
Indus Valley Civilisation, the early civilisation of India and Pakistan, developed the economy of agriculture and craft which later spread into central India. Angus Maddison estimates that from 1-1000 AD, the regions making up present-day India contributed roughly 30% of the world's population and GDP. India experienced per-capita GDP growth in the high medieval era.
