Medieval India refers to a long phase of Indian history that roughly spans from the 8th century to the early 18th century. This period began after the decline of ancient regional kingdoms and ended with the gradual expansion of European influence. It is generally divided into early medieval and late medieval phases. During this era, political power shifted among regional kingdoms, the Delhi Sultanate, and later the Mughal Empire. Medieval India is known for cultural exchange, administrative developments, architectural growth, and evolving social structures.
