Prince. Duke. Earl. Baron. There are a variety of titles men in the monarchy can be given these days. And, if we’re being completely honest, it can be difficult to keep track of the differences between them. We know Prince William also holds the title of Duke of Cambridge, Prince Harry is the Duke of Sussex, Prince Charles is the Prince of Wales and Prince Edward is the Earl of Wessex. But what makes William, Harry and Charles dukes? And what is a duke? 

First, it’s important to know that there are five possible titles for males in the peerage system (a legal system conferring titles of realms in the United Kingdom). Ranked from highest to lowest, they include duke, marquess, earl, viscount and baron.

So, what is a duke? 

A duke is the member of nobility that ranks directly below the monarch. It means the individual is a ruler of the “duchy” (a county, territory or domain).

How does someone become a duke? 

The title can either be passed down by a parent (aka inherited) or given as a title by a king or queen. It's also a tradition for men of the royal family to get a new title when they marry. For example, Prince William became the Duke of Cambridge when he married Kate Middleton in 2011, granting her the title of Duchess of Cambridge. Prince Harry became the Duke of Sussex after tying the knot with Meghan Markle, also making her his duchess. 

However, Prince Charles became the Duke of Cornwall at just 4 years old when the title was bestowed on him by the queen. 

How do you address a duke? 

Formally, a duke should be addressed as “Your Grace.”

Are all Princes also Dukes? 

Nope. In short, princes are born and dukes are made. Take Prince Edward for instance. Queen Elizabeth’s youngest son was not given a duke title when he got married. Instead, he became the Earl of Wessex. However, he will inherit the title and be named the Duke of Edinburgh, upon the death of his father.
