Nobility refers to a social class that is often associated with hereditary titles and privileges. Members of the nobility, known as nobles, typically hold a higher status in society compared to common people. This class has historically been linked to land ownership, governance, and military leadership, often serving as advisors to monarchs or ruling over regions. In many cultures, the concept of nobility includes a code of conduct that emphasizes virtues such as honor, loyalty, and service. Nobles may be granted titles like duke, count, or baron, which can vary by country. The role and influence of nobility have changed over time, especially with the rise of democratic systems.
