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 the present-day India contributed roughly 30% of the world's population and GDP.
India experienced per-capita GDP growth in the high medieval era, coinciding with the Delhi Sultanate. By the late 17th century, most of the Indian subcontinent had been united under the Mughal Emperor Aurangzeb, which for a time Maddison estimates became the largest economy and manufacturing power in the world, producing about a quarter of global GDP, before fragmenting and being conquered over the next century.
