Excluding the old Soviet states and not including instances where countries have split, and more than one changed their name, for example 'Serbia and Montenegro' -> 'Serbia' and 'Montenegro'
Excluding name changes that have happened slowly over time, for example 'Czhech Republic' -> 'Czechia'
Only counting the latest name change if a country has changed name muntiple times
