Specific to the US in examples but it a universal question: How would a regime “erase history”

So if you’re at all plugged into the news you’ll recognize this phrase. People will say your “erasing history” by taking down a confederate statue or removing someone’s name from a building. Obviously this isn’t erasing squat but it got me thinking about actual attempts to erase the history of a people by a dominating force, be they a ruling class or a invader.

All I could think of was genocides or ancient empires using forced integration/slavery and razing cities (which I think we could use as a pretty good stand in for genocide).

I do know of a Egyptian attempt to erase a Pharaoh from their records ... but I know about that so I guess it didn’t really work. Native American history was deeply impacted by the genocide they suffered in because much of their history was oral. So in this way it truly does “erase history” to exterminate a village. The knowledge quite literally dies with them.

Wondering if any other history junkies have an opinion.
