Historical

The late King Bhumibol holds the modern record for longevity on the throne with a reign of 70 years. 

Before King Bhumibol, the modern record for longevity was held by Japanese Emperor Hirohito, who died in January 1989 at the age of 87 after reigning for 62 years.

In Europe, the longest verified reign is that of French King Louis XIV (72 years between 1643 and 1715). Austrian emperor Franz Joseph I reigned for nearly 68 years between 1848 and 1916.
