longestruling

Longestruling is a term used to describe the longest reigning monarch in history. This designation is typically awarded based on the duration of a sovereign's rule, from their accession to the throne until their death or abdication. The criteria for determining the longest ruling monarch can sometimes be a subject of debate, particularly when considering periods of regency or disputed claims to the throne.

The most commonly cited individual for the longest reign is Louis XIV of France, whose rule spanned 72 years and 110 days. He ascended to the throne in 1643 at the age of four and reigned until his death in 1715. Other notable long-reigning monarchs include Bhumibol Adulyadej of Thailand and Elizabeth II of the United Kingdom, both of whom also had reigns exceeding 70 years. The longevity of these rulers often reflects periods of stability, significant historical events, and the personal endurance of the monarchs themselves. Tracking longest reigns provides a unique perspective on the history of various monarchies and the individuals who have held such power for extended periods.
