As far as I'm aware national parks in the US were created on land that didn't really have anyone living in it (maybe Indians in some of them), you'd have to go back to the early middle ages to find similar areas in Europe (I'm guessing but at least in places like Italy I'm fairly sure of that)

I really really wish we had similar expanses of untouched nature here in Europe but unfortunately it was all gone by the time people started seeing untouched nature as something to preserve
