Dukes typically hold significant social status and may govern a specific region or territory, known as a duchy. In historical contexts, ducal titles have been associated with royal families and the ruling class in various countries, including England, France, and Italy. The role of dukes has evolved over time, but they often played important parts in politics, military leadership, and local governance.
