Duchys
A duchy is a territorial division historically governed by a duke or duchess. Duchies were significant political entities in many European feudal systems, often ranking in importance below kingdoms and principalities. The title of duke or duchess was typically a high noble rank, frequently hereditary and associated with substantial landholdings and political influence. The specific powers and responsibilities of a duke varied depending on the historical period and the sovereign under whom they served. In some cases, duchies were virtually independent states, while in others, they were subordinate administrative regions within a larger kingdom. The concept of a duchy has its roots in the late Roman Empire and evolved significantly throughout the Middle Ages and into the early modern period. Many modern countries have historical territories that were once duchies, and the term still appears in some ceremonial titles and geographical names.
