Since Russia annexed Crimea there have been a number of videos such as the one below about how European and Eastern Asia borders have changed over time, but this is one of the very best of them ( at tip of the hat to Marc to Market).
Of course, what’s interesting about this is that Crimea has been part of Russia for the vast majority of the last 300 years. That’s pretty much the case for Ukraine as well, but aside from Russia, there are few (if any) other regions that are quite as Russian as Crimea.
