Throughout European history, the nobility formed a powerful and privileged class, deeply entwined with monarchy, land ownership, and military service. Titles such as duke, count, and baron varied by region but often signified hereditary status and influence. Nobles held legal and social privileges, including tax exemptions and political authority, especially before the rise of modern nation-states. While their power waned after revolutions and reforms, aristocratic families continued to shape culture, diplomacy, and tradition across the continent.
