What is titled nobleman and peer?

A titled nobleman is an individual who holds a hereditary or granted title of nobility, such as duke, marquis, earl, viscount, or baron. A peer is a member of the aristocracy, typically one who has been granted a title and holds a rank within the peerage system, often with certain privileges and responsibilities. In many countries, peers may have historical roles in governance, such as sitting in a legislative body. Both concepts are integral to the social hierarchy in noble traditions, particularly in countries like the United Kingdom.
