Nobody's conquered the US yet, mind you. And recent history's going to be felt more intensely than ancient. All well and good talking about the Mayans and Aztecs and whomever, but there are people still living who've suffered as a result of US policy.
FYI: There are still non-hispanic Aztecs and Mayans alive today that even still speak the language
The bigger picture is called natural history and every poet should know it
They won't have direct experience of being conquered during those societies' heyday in the way people still living in Chile will have experienced living through a US-backed coup in the 70s though.
but they're still being persecuted and going through genocides.
