Most people interested in royalty find a comfort area and choose to stay there.
It is interesting to note that in Anglocentric royal history, the one and only focus is on the English Channel. Anglo-French alliances are paramount. Compare this with how the Baltic, with all its important history of Viking and German eastward expansion, the dominance of the Hanseatic League, the rise and fall of Poland and Sweden and the Russian westwards expansion, is a "mare incognitum" to the Anglocentric readers of history.
How many of them have any idea of how much the succession disputes of the Kalmar Union resemble the Wars of the Roses and the Hundred Years War, so much in fact that Henry IV obtained some legal counsel from his "fellow usurper" Queen Margrethe when his daughter Philippa married Erik of Pomerania.
