A golden jubilee is a celebration held to mark a 50th anniversary.
The golden jubilee is a royal ceremony to celebrate the 50th anniversary of the accession of the king. The Thai word is kanchanaphisek (กาญจนาภิเษก). The first Golden Jubilee of Thailand was the celebration of King Bhumibol Adulyadej.
King Rama IX celebrated his golden jubilee on 9 June 1996, having acceded to the throne in 1946 which makes him Thailand's longest-reigning monarch and the longest-living monarch today.
The largest faceted diamond in the world, known as the Golden Jubilee Diamond, was purchased as a gift for the King on the 50th anniversary of his coronation by Thai businessmen. Currently, the diamond is located in the Royal Thai Palace as part of the crown jewels.
The symbol of the golden jubilee
The symbol of the golden jubilee of King Bhumibol Adulyadej was designed by Wiyada Charoensuk, who won the contest for the design.
There are three parts to the design:
- The King’s throne (in center) is a sign of the Jakkree dynasty (the dynasty of King Bhumibhol)
- The white tiered umbrellas of kingship, which represent the constitution of Thailand
- The two Elephants, which represent the Thai people
The Fine Arts Department wanted this design to:
- Celebrate the King
- Help Thai people remember Thailand's tradition
- Show that Thais are proud to be people of their King
- Show that Thais have a long history as a Thai nation

For Queen Victoria
In 1887 the United Kingdom and the British Empire celebrated Queen Victoria's golden jubilee. Victoria marked 20 June 1887—the fiftieth anniversary of her accession—with a banquet, to which fifty European kings and princes were invited. Although she could not have been aware of it, there was a plan by Irish Republicans to blow up Westminster Abbey while the Queen attended a service of thanksgiving. This assassination attempt, when it was discovered, became known as the Jubilee Plot. At the time, Victoria was an extremely popular monarch.
