Besides that, multiple ways to read this. "Monarchies" could've been a reference to pre modern monarchies of which many made it through at least 3 successions. Or as a correction to the upper comment, saying that the Kim's are more monarchy than plain dictatorship.
The British Crown had to concede some rights centuries ago, or there would have been civil wars and probably no more crown. Dear Leaders are the ones that don't have to concede anything, yet.
Not only have there been multiple civil wars, there has also been “no more crown” after the beheading of King Charles I (1649) until the restoration in 1660.
