Karl Thopia (Albanian: Karl Topia; c. 1339 – January 1388) sometimes written as Charles Thopia, was an Albanian feudal prince and warlord who ruled Albanian domains from 1358 until the first Ottoman conquest of Albania in 1388.
According to the tag definition for m:gender change: For parodies (e.g. female ranma saotome) the change itself does not have to be shown.
Karl Thopia was a dude in real life, and unlike with Fate/'s genderbends this seems to be entirely based on IRL history rather than an alternate version, so I'd argue gender change still applies.
