An earl is a noble title in the British peerage system, ranking just below a marquess and above a viscount. The title has historical roots, dating back to the Anglo-Saxon period, where earls were local leaders or governors of regions. Today, earls often play ceremonial roles and may have estates or land associated with their title. Earls are usually addressed as "Lord" and their wives as "Lady." The title can be inherited or granted by the monarch. Many earls have rich family histories and are associated with grand estates, such as castles or manors, that reflect their noble heritage.
