👉 The term "archduke" is primarily associated with the royal family of Austria in Europe. Archdukes are members of the House of Habsburg-Lorraine, and they are typically appointed by the Holy Roman Emperor to serve as regents or advisors during times of crisis, such as when their father's reign is overthrown. The term "archduke" can also be used metaphorically to describe someone who holds a high position in society, especially within a political or military context.
