There are many movies about certain nations . But basically, make up a movie(s) or show(s) for the nations (Pre-1900), as if they survived in the modern day to make these movies and shows, while keeping a cultural setting (Like if making a Aztec movie, set in the Aztec Empire). It can range from fictional superhero movies set in the nation, to romanticized retelling of the past, to an cutesy animated flick. Examples include:
Aztec Empire
Holy Roman Empire
Mughal Empire
Confederate states of America
Republic of Venice
Ming dynasty
