What were the results of the invasion of the Huns over India during the 5th century?

The following were the impacts of the invasion of the Huns over India during 5th century:

1. End of the Gupta Empire: The successors of Samudragupta were so weak, the entire empire were dashed to the ground by the Huns.

2. End of political unity: India’s political solidarity came to an end on account of the rise of petty states.

3. Destruction of historical sources: The Huns burnt  important books on history and the splendid buildings to ashes.

4. Mixing with the Indian Society: Many Huns got settled into India itself after the invasion. They got merged into Indian society by marrying the Indian women. So many castes and sub-castes emerged after that.
