Nobility refers to a social class that is often associated with hereditary titles and privileges. Members of the nobility, known as nobles, typically hold significant power and influence within a society. Historically, they have played important roles in governance, military leadership, and land ownership, often serving as advisors to monarchs or ruling over specific regions. The concept of nobility varies across cultures and time periods. In many societies, such as medieval Europe, nobility was linked to feudal systems, where land was granted in exchange for loyalty and service. Today, while the political power of nobility has diminished in many places, titles and traditions still exist in some countries, such as the United Kingdom.
