Medieval India was a long period of post-classical history in the Indian subcontinent between the ancient and modern periods. It is usually regarded as running approximately from the break-up of the Gupta Empire in the 6th century to the start of the early modern period in 1526 with the start of the Mughal Empire, although some historians regard it as both starting and finishing later than these points. The medieval period is itself subdivided into the early medieval and late medieval eras.
In the early medieval period, there were more than 40 different states on the Indian subcontinent, which hosted a variety of cultures, languages, writing systems, and religions. At the beginning of the time period, Buddhism was predominant throughout the area, with the Pala Empire on the Indo Gangetic Plain sponsoring the Buddhist faith's institutions. One such institution was the Buddhist Nalanda mahavihara in modern-day Bihar, a centre of scholarship which brought a divided South Asia onto the global intellectual stage. Another accomplishment was the invention of Chaturanga, which later was exported to Europe and became chess.In Southern India, the Tamil Hindu Cholas gained prominence with an overseas empire that controlled parts of modern-day Sri Lanka, Malaysia, and Indonesia as overseas territories, and helped spread Hinduism and Buddhism into the historic cultural area of Southeast Asia. In this time period, neighbouring regions such as Afghanistan, Tibet, and Southeast Asia were under South Asian influence.
