Why cardinal Richelieu though?? The story seems to take place at the starting of the German Empire, in the last third of the 18th century, based off the names and the current fashion. Cardinal Richelieu "served" Louis XIII, ROI de France et de Navarre (king of France and Navarre), in the first half of the 17th century.
Also, this "stupid a$s religion" y'all are talking about is Christianity, and yes, that is how they perceived women until not long ago. Now they're very "egalitarian".
On a much brighter note, it seems the Crown Prince has taken a liking to Shuli. 😏 Just don't go running at her feet too soon.
