A duke is a high-ranking noble title in many countries, often associated with royalty. Dukes typically oversee large areas of land and have significant influence and power. In the past, they were important figures in the feudal system, serving kings and queens while managing their territories. The title of duke is often passed down through generations, making it a hereditary position. In modern times, dukes may not hold the same political power, but they still carry prestige and are often involved in charitable activities. Famous dukes, like the Duke of Edinburgh, have played important roles in their countries, representing tradition and history.
