In present day India the ruling party has started to rename the cities by claiming to take them to their origins. It has been discussed here, here and here. Primarily the cities with Muslim Names for instance Allahabad was changed to Prayagraj saying that it was it's original name and the Akbar changed it during his conquest. There have been cases when things were named after Muslims as well for instance an Island was named after APJ Abdul Kalam India's Former President and regarded as the Missile Man of India.
Also India's curriculum is being rapidly rewritten as mentioned here, here, here and here. This also includes historically incorrect facts and data such as that the Indian Kings defeated the Mughals when they clearly lost and had to run away which are in accordance to claims of members of Ruling Party but are historically wrong.
I was searching for previous historical precedent in other countries in both modern and ancient times for a project where actions were taken due to similar reasons but was unable to find any such incident. Has there never been such a mass renaming, rewriting of history and changing of facts earlier? If yes please comment on how did people react to losing their heritage and identity. Also please share some specific examples also.
