The Nobility of Europe refers to a social class that historically held privileges and power, often linked to land ownership and titles. This class emerged during the Middle Ages and played a significant role in the political and economic structures of various European countries. Nobles often served as advisors to monarchs and were responsible for local governance. Noble titles varied across regions, including dukes, counts, and barons. The influence of the nobility began to decline with the rise of democracy and capitalism in the 18th and 19th centuries, leading to significant social changes across Europe.
