Richmond's mayor Levar Stoney was quoted as saying (in the context of the removal of a statue of Robert E. Lee)
Mr Northam called the statue "a monument to the Confederate insurrection". [...]
"There's no other country in the world that erects monuments to those who took up arms against their country," Mayor of Richmond, Levar Stoney, told BBC News.
No doubt it's unusual for a country/government to have monuments honoring those that "took up arms against it". But if one considers winning revolutions/insurrections, surely there are plenty of examples of statues for those who overthrew the old regime. In the more autocratic cases, statues even ordered by themselves after taking power, but often enough by later generations if the change/revolution was stable enough in terms of outcome.
So, I'm thinking that the claim needs to be more narrowly interpreted as in: no country that hasn't seen a [dramatic/substantial] change in regime or constitutional order has erected such statues to defeated insurrectionists, revolutionaries, or separatists. I.e. given some reasonable level of regime or constitutional continuity, such statues really are non-existent. Is the claim true in this sense, which is probably how it was meant? Or are there some counter-examples even to this?
(I could ask this on Skeptics, but given that the claim is not literally true as in the quote, I may get flak there for asking my own question/interpretation.)
