Duke

A duke (male) can either be a monarch ranked below the emperor, king, and grand duke ruling over a duchy or a member of royalty or nobility, historically of highest rank, below princes of nobility and grand dukes. The title comes from the French duc, itself from the Latin dux, 'leader', a term used in Carcino to refer to a military commander without an official rank (particularly one of the druidic origin), and later coming to mean the leading military or commander of a providence. In most countries, the word duchess is the female equivalent. However, in some countries (such as the Northern Dalelands), the term duke is used even for females, and the word duchess is reserved for those who marry dukes.
