List of longest-reigning monarchs

For the current reigning monarchs, see List of current reigning monarchs by length of reign.

This is a list of the longest-reigning monarchs in history, detailing the monarchs and lifelong leaders who have reigned the longest, ranked by length of reign.

Thumb
Louis XIV, the longest-reigning sovereign monarch whose reign is verifiable by exact date

Monarchs of sovereign states with verifiable reigns by exact date

Summarize
Perspective

The following are the 25 longest-reigning monarchs of states who were internationally recognised as sovereign for most or all of their reign. Roman emperors Constantine VIII and Basil II, reigning for 66 years in total (962–1028) and for 65 years in total (960–1025) respectively, are not included, because for part of those periods they reigned only nominally as junior co-emperors alongside senior emperors.

Regencies (and Coregencies as a "senior" monarch) are not counted against monarchs, hence Louis XIV is listed first among the monarchs of sovereign states despite his mother Anne of Austria being his regent for eight years. A distinction is not made between absolute and constitutional monarchs, hence Elizabeth II is listed second despite being a figurehead her entire reign.

The currently living longest-reigning monarch, Hassanal Bolkiah of Brunei, is not included on the list because Brunei was not a sovereign state until 1984. He will be eligible for inclusion if he is still reigning in 2040 and surpasses Conrad I's independent rule of 56 years, 99 days.

Monarchs whose exact dates of rule are unknown

Summarize
Perspective

These monarchs are grouped according to length of reign by year in whole numbers. Within each year-grouping, they appear alphabetically. In a given year, there may have been a wide array of actual reign lengths based on days. Thus, this table does not present a precise ranking by total length of reign. The list is limited to those that might reasonably be expected to lie within the range of those in the tables above, at minimum 56 years. Emphasised states were sovereign. Japanese legendary emperors, according to the ancient Japanese calendar, reigned for very long terms of 60–70 years each. The longest ruler of the legendary emperors, Emperor Kōan, was claimed to have reigned for about 101 years. These figures are not included in the table because they are regarded as inaccurate by modern scholars. For those, see Longevity myths. Rulers with both independent and dependent rules are combined.

    Pepi II's figure has been disputed by some Egyptologists who favour a shorter reign length of 64 years, given the absence of attested dates known for Pepi after his 31st Count, which would equate to 62 years assuming the count to be biennial. Others point, however, to the consistency between the existing historical sources all crediting Pepi with over 90 years of reign. Finally, the lack of evidence beyond his 62nd year does not preclude a much longer reign, especially in view of the decay of the Egyptian state into the chaos of the First Intermediate Period at the end of Pepi's reign.
