A peerage system is a hierarchical structure of nobility within a society, often associated with titles and privileges. In many countries, such as England and France, the peerage includes ranks like duke, marquess, earl, viscount, and baron. These titles can be hereditary, passed down through generations, or granted by a monarch or government. Peerage systems often play a role in governance and social status. Nobles may have specific rights, such as land ownership or participation in legislative bodies, like the House of Lords in England. The system reflects historical power dynamics and social organization within a culture.
