Exactly what I first thought but I searched it up and it actually differs from country to country. Sometimes it may be lower to that of a prince, sometimes higher or sometimes equal.
"In England, a prince or princess are often children of the monarch, and therefore royalty, as opposed to nobility. But, those holding the title can vary in rank. In France, a duke, or "duc" outranks a prince. In Russia and Austria, the title archduke is an indication of royal blood, and is used instead of prince. In the UK, the eldest son of the monarch is given the title Prince of Wales, as is currently held by Prince Charles. A prince or princess would typically be referred to as "your royal highness."
"A duke, from the Latin dux (another word for a military leader), is the ruler of a dukedom or duchy. If the dukedom is an independent country, its leader may be called a grand duke. Originally allEnglish dukeswere of royal blood. When sons of kings came of age they were typically given the title duke. Now a duke is the highest rank of English nobility. Ducal status is conferred by marriage, as in the case of Kate Middleton, the Duchess of Cambridge, or Meghan Markle, the Duchess of Sussex. A prince, as such, is typically a prince and a duke; Prince William and Prince Harry are Princes of the UK, while also being called the Duke of Cambridge and the Duke of Sussex respectively. A duke would typically be addressed as "your grace," as would an archbishop."

Ahh, I guess that would make sense! Thanks for taking the time to copy and paste this lol
Aw, this is cute. Anyways, I’m kinda confused about how can the Archduke attack his own prince..? Like yeah, I know that archdukes have the highest position in nobility but, of course the prince has a higher position. Just asking how is he allowed to do that?? I’m still kinda new to stories with nobility and royalty stuff so I’m just curious (=・ω・=)
