For thousands of years, India stood as a flourishing civilisation, rich in knowledge, trade and culture. It was the golden sparrow that sent Columbus sailing west in 1492 in search of its fabled wealth. Economic historian Angus Maddison estimated that until the early 18th century, India contributed nearly a quarter of the world’s GDP. Its weavers clothed empires, its thinkers shaped mathematics and its merchants carried spices and silk across continents. Then, far away in England, something happened that changed the order of the world.
