Well, the Jacobite conflict wasn‘t the only one in the 18th Century bearing traces of what‘s to come. The 7 Years War was also a propaganda war, with Prussia very much styling itself as a) defender of Protestants against evil oppressive Catholics (never mind that of the four opposing monarchies, one was Sweden and one was Russia), and b) defender of Germans against invading foreigners whereas the Austrians were teaming up with them. This, btw, makes for a crossover of the preceding century where the 30 Years War of course started as a gigantic war of religion and the upcoming one with its rise of nationalism. It also was pretty successful with the majority of German speaking writers at least, who are the ones leaving behind pamphlets, articles and poetry.

(Not to mention, of course, that in the 19th Century once Prussia had completed its rise to the top the Prussian pov became the official German pov of history, and it took eons until this changed again.)

And then, near the end of 18th century, you get the French Revolution, and subsequently Napoleon, at which point it‘s both ideology and rising nationalism time everywhere. The war against revolutionary France after the executions of their royals was very much the antithesis to all those succession wars that dominated the first half of said century, and if you look at the text of the Marsaillaise, written during this time, you get the wish for the blood of the invaders to drench the acres of France and la patrie and what not. Which fits - here, you had to motivate and mobilize a great number of underequipped people, and then they actually won, to the great surprise of the monarchies allied against them. And then, of course, once Napoleon makes it to the top, he explicitly frames his territorial go getting in terms of France „liberating“ other countries via exporting the revolution‘s gains to them, while the fight against him gets increasingly framed in modern national and ideological terms in Spain, Russia and Germany, and the connection of having to motivate an ever greater number of less and less illiterate people is most definitely there!
