There was not a large and unified Hindu nations, but instead there were multiple smaller ones that were constantly wasting their resources on fighting with one another. The Mughals used this situation and managed to conquer the northern part of India without any particular problem. This led to the establishment of the first Muslim Empire on Indian soil, and that led to Islamization of lot of people in that area over the course of several centuries.
