A Duke is the highest-ranking hereditary title in most countries, below the Prince. There are both Royal Dukes and non-royal Dukes. Royal Dukes are part of the ruling royal family of the country. These Royal Dukes hold both their royal title and up to multiple dukedoms elsewhere in their country or others. 

Each of the children of the present monarch, hold their own title besides their royal one. As they move up in rank, the title goes to their children. Dukedoms are a hereditary title, if a female inherits, they are called a Duchess. Some dukedoms can only be held by the firstborn of the respective Sovereign. 

A duke outranks all other holders of titles of nobility (marquess, earl, viscount, and baron; not all countries have these other titles). The wife of a duke is a duchess, as well as a woman who holds the same title. Although the husband of this type of duchess, doesn't hold the title of duke. Non-royal dukes without state offices or positions take precedence before other nobility, date of creation, but after royalty and officers of state.

A duke is a royal commander within his dukedom. They are the rulers of provinces and the superiors of counts in the cities. In some countries, dukes are the rulers and are called Grand Dukes.
