A peerage is a system of titles of nobility in certain countries, particularly in the United Kingdom. It includes ranks such as duke, marquess, earl, viscount, and baron. Individuals who hold these titles are known as peers and often have historical ties to the monarchy or land ownership. Peerages can be hereditary, passed down through generations, or life peerages, which are granted for the lifetime of the individual. In the UK, the peerage system is part of the British aristocracy and plays a role in the House of Lords, the upper chamber of Parliament. Peers may have the right to sit in the House of Lords, participate in debates, and influence legislation. The peerage system reflects the historical social hierarchy and continues to be a significant aspect of British culture and governance.
