A Marquessate is a noble title in the hierarchy of the British peerage, ranking above an Earl and below a Duke. The title is typically granted to a noble who governs a specific area known as a march, which historically served as a border region. The holder of a marquessate is referred to as a Marquess (or Marchioness for females) and often has significant social and political influence. Marquessates are hereditary, meaning they can be passed down through generations, usually to the eldest son. The title often comes with a seat in the House of Lords, allowing the marquess to participate in the legislative process. Notable examples of marquessates include the Marquess of Bath and the Marquess of Salisbury.
