List of current reigning monarchs by length of reign
This is a list of currently enthroned monarchs sorted by length of service. It includes monarchs who do not reign over entire nations, such as Muhammad V of Kelantan, but does not include former monarchs and pretenders, such as Simeon II of Bulgaria, ex officio monarchs such as Emmanuel Macron who in his capacity as President of France is also Co-Prince of Andorra, monarchs without physical territories such as the Prince and Grand Master of the Sovereign Military Order of Malta, constituent monarchs such as the traditional African rulers, or monarchs whose position is unofficial, such as Tenzin Gyatso, 14th Dalai Lama.
Elizabeth II is currently the longest-reigning monarch, having been Queen of the United Kingdom, Canada, Australia and New Zealand since 6 February 1952. She is also the monarch of 12 other Commonwealth realms which have become independent states since 1952; she is therefore listed multiple times in the table below.List
