Peerage titles are ranks of nobility in the United Kingdom, traditionally associated with land ownership and social status. The main titles include Duke, Marquess, Earl, Viscount, and Baron. Each title can be hereditary, passed down through generations, or life peerages, which are granted for an individual's lifetime. These titles often come with specific privileges and responsibilities, such as the right to sit in the House of Lords. The peerage system has historical roots, dating back to the medieval period, and continues to play a role in British society and governance today.
