In the Middle Ages, the Indians were all tribes until a man named SkandaGupta came and started uniting all the tribes and kingdoms and started the Gupta Dynasty.
This was during Golden Age of India when everyone was doing great things like math, writing, medicine, astronomy.
After the fall of Rome the Byzantine Empire and the Indian Empire were strong against the barbarians. Then the Huns attacked the Gupta empire and SkandaGupta led his people against them and beat them but just barely.
They lost so many people fighting the Huns that the Indian people became poorer and the empire fell apart and the Golden age ended.
